Chinese elder (Sambucus javanica), also called Javan elder, is a shrub, growing to 4 m tall, which is distributed from India eastwards to China, Taiwan, and Japan, and thence southwards through Southeast Asia to Indonesia and the Philippines.

This plant grows on mountain slopes, along rivers, and in forests and grasslands, from the lowlands up to an altitude of c. 2,600 m. Its berries, which may be black, red, or orange, are edible, as are the flowers, and other parts of the plant are widely used in herbal medicine.

Other species of elder are described elsewhere on this website, common elder (S. nigra) on the page Plants: Plants in folklore and poetry, blue elder (S. cerulea), sometimes called Mexican elder (S. mexicana), on the page Plants: Plants of Sierra Nevada, and red elder (S. racemosa) on the page In praise of the colour red.

Daoist festivals, and many other aspects of Daoism, are described in detail on the page Religion: Daoism in Taiwan.

 

In certain fishing communities in southern Taiwan, people still celebrate the so-called Boat Burning Festival, a Daoist festival, during which a complete wooden boat is built, only to be burned as an offering to the god of diseases, Wang-yeh, hoping that he will spare the people of the plague and other dreadful diseases.

In former times, the burning boat was pushed out to sea, ceremonially carrying the diseases away, but this practice has now been abandoned, and the boat is burned on land.

As its name implies, the desert globemallow (Sphaealcea ambigua) is partial to desert areas, found in all of the Mojave Desert, Great Basin Desert, and Sonoran Desert ecoregions, in the states California, Nevada, Utah, Arizona, and New Mexico in the United States, and Sonora and Baja California in north-western Mexico.

This shrub, which is a member of the mallow family (Malvaceae), thrives on alkaline soil, sandy as well as clayey, up to an altitude of about 2,500 m.

The orange (Citrus x sinensis) is a hybrid between pomelo (C. maxima) and mandarin (C. reticulata). It originated in China and was mentioned in Chinese literature as early as 314 B.C. (Source: Xu et al. 2013. The draft genome of sweet orange (Citrus sinensis). Nature Genetics 45: 59-66)

Incidentally, the name of the colour orange stems from the fruit – not the other way around. The word comes from the Old French orange, which, in turn, is from the Italian arancia, based on Arabic naranj, which is derived from the Sanskrit word for the fruit, naranga.

Nightshade (Solanum) is one of the largest plant genera in the world, counting more than 1,300 species, including a number of very important food plants, e.g. potato (S. tuberosum), tomato (S. lycopersicum), tomato tree (S. betaceum), and eggplant (S. melongena).

The generic name is of unknown origin, possibly derived from the Latin sol (’sun’) referring to the fact that plants of this genus prefer to grow in sunny places.

Fruits of these plants may be red, orange, yellow, or black. Two species with orange fruits are described below, whereas others are presented on the pages In praise of the colour red, and Plants: Plants in folklore and poetry.

 

Indian nightshade (Solanum indicum, also called S. violaceum) is native to the Indian Subcontinent and Southeast Asia. It is a shrubby herb to 3 m tall, with spiny stems and sometimes also spines along the veins of the large, wavy leaves. The rather small berries, to 2 cm diameter, are orange or yellow.

Jerusalem cherry (Solanum pseudocapsicum) is widely cultivated as a house plant. It is native to the northern Andes, but has escaped in many other areas. In South Africa, India, Australia, and New Zealand, it is regarded as an unwanted weed. All parts of the plant are poisonous, especially the unripe fruits.

The specific name, meaning ‘the false capsicum’, refers to the leaves, which resemble those of green pepper (Capsicum).

The common name Jerusalem cherry is a misnomer, as the plant does not bear cherries, and it is not native to the area around Jerusalem. The name may simply stem from some gardener, who brought back the plant from Jerusalem and attached the name to the plant without researching its true native area. (Source: m.wisegeek.com)

Another common name, Madeira winter cherry, stems from the time when Portuguese sailors brought the plant from South America to Madeira. From here, it was introduced to Europe, where it became a status symbol among the upper classes.

The silk-cotton tree (Bombax ceiba), also called Indian kapok tree or simal, is a large tree of the mallow family (Malvaceae), native to Tropical Asia, southern China, and northern Australia. It is widely cultivated elsewhere for its gorgeous flowers, which are bright red in wild populations. In Taiwan, however, where the pictures below were taken, a cultivated form with orange flowers is very popular.

This species has countless medical usages, and is also utilized for many other purposes, described on the page Plants: Plants in folklore and poetry.

Pansies (Junonia), in America called buckeyes, are a worldwide genus, comprising about 33 species of butterflies of the huge brushfoot family (Nymphalidae).

The peacock pansy (Junonia almana) was named due to its large, bluish ‘peacock eyes’ on the orange wings. This species is distributed from India and Sri Lanka eastwards to China, Taiwan, and Japan, and thence southwards to the Indonesian Archipelago and the Philippines. It is very common, living in a wide variety of habitats up to an altitude of about 500 m, occasionally up to 1,000 m.

Glorybower (Clerodendrum) is a large genus of the mint family (Lamiaceae), counting about 150 species, which are native to Africa and Asia.

The pagoda flower (C. paniculatum), by some authorities called Javan glorybower, is a stout herb, sometimes growing to 2 m tall. It was named for its spectacular, pyramidal clusters of orange-red or scarlet flowers.

This plant is native to subtropical and tropical Asia, from India eastwards to southern China and Taiwan, and thence through Southeast Asia to Indonesia, the Philippines, and New Guinea. It is widely cultivated and often escapes, making it difficult to determine whether a population is genuinely wild or not.

A close relative, C. infortunatum, is described on the page Plants: Himalayan flora.

Asiatic sweetleaf (Symplocos paniculata) is a small tree, sometimes to 12 m high, which was formerly placed in the tea family (Theaceae), but has now been moved to a separate family, Symplocaceae. It is also called sapphire-berry due to its bright blue fruits.

The native range of this species is from Pakistan eastwards across the Himalaya to Southeast Asia, southern China, Taiwan, and Japan. In the Himalaya, it grows between 1,000 and 2,700 metres altitude, but elsewhere it may be found down to sea level.

It is widely cultivated due to its pretty flowers and gorgeous blue berries, which are eagerly sought out by birds. It has become naturalized in some places, including the United States, where it has been declared an invasive species.

The tree sparrow (Passer montanus) has a huge distribution, from western Europe across Central Asia to Japan, and thence southwards through Southeast Asia to Indonesia and the Philippines.

 

 

The tree sparrow is very common in Taiwan, where it has taken over the role of the house sparrow (P. domesticus) as a city bird, as the latter is not found on the island. These birds are sitting on an orange metal sculpture in the city of Taichung. (Photo copyright © by Kaj Halberg)

 

 

 

 

The place of origin of the coconut palm (Cocos nucifera) is unknown, and today it is found everywhere along tropical coasts, in some areas also inland.

This species is utilized for countless purposes. Oil from the nuts, and also dried copra, is used for cooking and in lamps. Mats, weaved from the leaves, are used as walls and roofs in houses, and mats and rope are produced from the fibres in the husk. Charcoal is made from the shells, and the trunk is utilized as timber and firewood.

Golden dewdrop (Duranta erecta) is a small shrub of the vervain family (Verbenaceae), which is native from Mexico and the Caribbean southwards to Paraguay and Argentina. Elsewhere in warmer countries, it is widely cultivated as an ornamental and has become naturalized in many places. It is regarded as an invasive species in a number of countries, including Australia, China, and South Africa, and on several islands in the Pacific.

Other common names of this plant include pigeon berry and Brazilian skyflower, and in Tonga it is known as mavaetangi (‘tears of departure’), alluding to the fruit, which is a small, globose, yellow or orange berry, to 1 cm across. Unripe berries are toxic and are known to have killed children, dogs and cats. Birds, however, are not harmed by the berries.

The generic name was given in honour of Italian physician, botanist, and poet Gualdo Tadino (1529-1590), better known as Castore Durante da Gualdo.

A picture, depicting the flowers, is shown on the page In praise of the colour blue.

Scarlet milkweed (Asclepias curassavica) is a native of the West Indies, but is widely cultivated as an ornamental in tropical and subtropical areas and has become naturalized in many areas.

According to Kew Bulletin (1897), this species has insecticidal properties, being especially obnoxious to fleas. Infected rooms are thoroughly swept with brooms, made from this plant, and the pests are said to disappear. Its medicinal usage is described on the page Plants: Plants in folklore and poetry.

In his delightful book All about Weeds, American botanist Edwin Spencer (1881-1964) writes about pollination of milkweeds:

“(…) they have one of the most distinct flowers of the plant kingdom. It is made for the purpose of tricking insects in order that cross fertilization may be assured. (…) insects attempting to get nectar from the cups in the flower. There are five of these cups on each flower, and they usually are found hanging mouth downward. They are very smooth, and a foot of the insect that tries to alight on one of them invariably slips off and lands on the slit, which lies between two of the cups. This is exactly what should happen; the very purpose for which the flower was made. In that slit lies the male principle of the flower in such a position that it may never come in contact with the female organ, unless it is pulled out and pulled in again. So the foot of the insect goes into the slit and finds itself caught as if between two tough little wires. If the insect is strong enough, a jerk or two will bring out the foot, and along with it two little bags of pollen, which ride away on the insect’s leg to another flower, where the foot again slips into a slit, but this time carrying the pollen bags (…) right down upon the stigmatic surface of the female organ. There the bags stay, and the pollen in them develops as it should (…). Of course, that same insect leg may come out of the second flower slit with two more bags of pollinia hanging to it like two little saddle bags. (…) it takes a strong leg to do this work, and strong insects are sometimes seen with several bags of pollinia hanging to their legs. If the insect is not strong enough, he pays dearly for the sip of nectar he gets. (…) if he cannot pay for that nectar by carrying away to another flower those two little pollinia bags, he hangs there until he dies (…).”

Even though the Daurian redstart (Phoenicurus auroreus) is called redstart, it is more orange than red. The male has orange-red breast, belly, and tail, black face, throat, and back, greyish crown and nape, and a prominent white wing-patch.

Like most of the 14 species in this genus, the Daurian redstart is strongly sexually dimorphic, the female being pale brown with an orange-red tail. Like the male, however, it has a prominent white wing-patch.

It breeds in south-eastern Siberia, from Lake Baikal eastwards to Amurland, Ussuriland, and Sakhalin, and in Mongolia, Tibet, most of China, and northern Korea, wintering in southern China, Japan, Taiwan, north-eastern India, and Southeast Asia.

Plants of the genus Calochortus can be divided into three distinct groups: mariposa tulips, or mariposa lilies, which have open, wedge-shaped petals; globe lilies with globe-shaped flowers; and cat’s ears and star tulips, which have erect, pointed petals. These gorgeous lilies are almost exclusively found in the western United States. The generic name is from the Greek kalos (‘beautiful’) and chortos (‘grass’).

Other pictures, depicting these lilies, may be studied on the page Quotes on nature.

The oriental hard fern (Blechnum orientale) is a large fern, with fronds sometimes reaching a length of 2 m. This plant is distributed from the Indian Subcontinent eastwards to southern China, Taiwan, and southern Japan, and thence southwards through Southeast Asia to New Guinea, Australia, and islands in the western Pacific. Elsewhere, it is cultivated as an ornamental, and plants are sometimes harvested from the wild to be used for food or medicine.

Minivets (Pericrocotus) are about 15 species of passerines, belonging to the cuckoo-shrike family (Campephagidae). They are found in forests from eastern Iran and Afghanistan eastwards across the Indian Subcontinent and China to Russian Ussuriland, and thence southwards through Japan, Taiwan, Southeast Asia, and the Philippines to Indonesia.

Several of the species are very colourful, the males displaying a predominantly bright red plumage, the females predominantly a yellow plumage.

The brilliantly coloured orange minivet (P. flammeus) lives in dense forests, from western India and Sri Lanka eastwards to southern China, and thence southwards through Southeast Asia to Indonesia. Formerly, this species was regarded as a subspecies of the scarlet minivet, which is now called P. speciosus.

Other species of minivet are described on the pages Animals – Birds: Birds in Taiwan, and Birds: Birds in Bagan.

Orange hawkweed (Pilosella aurantiaca) is a beautiful composite of open grasslands and wastelands, which is native to the major part of Europe, as well as north-western and central parts of Asia.

Due to its pretty flowerheads, it has also been introduced to a number of other countries, including England, Ireland, the United States, Canada, Australia, and New Zealand. However, it easily escapes and often becomes invasive, and in the latter two countries, import of the plant is prohibited.

This species has a number of peculiar common names, including fox-and-cubs, Devil’s paintbrush, and Grim-the-Collier (another name for the Devil). The name fox-and-cubs refers to the fact that the flowerheads on a plant do not all open at the same time. An open flowerhead is likened to a fox, whereas the buds beside it are the cubs. The other names refer to the invasiveness of this species.

Flame-vine (Pyrostegia venusta), also called orange trumpetvine, is a climber of the family Bignoniaceae. It is a native of Brazil, but due to its brilliant flowers it was introduced to numerous other countries at an early stage.

The generic name is from the Greek pyro (‘fire’) and stegia (‘cover’), the former referring to the flower colour, the latter to its vigorous climbing habit, as it will often cover entire buildings. The specific name stems from Ancient Italian wenostos (‘beautiful’).

Orange lichens of the genus Xanthoria, belonging to the family Teloschistaceae, are distributed worldwide, growing commonly on tree bark, walls, or rocks. They may be identified by the distinctive sporocarps (fruiting bodies), popularly called ‘fairy cups’.

Common orange lichen (X. parietina), also known as yellow scale or shore lichen, has a very wide distribution, found in most of Europe, Africa, Asia, Australia, and North America. As it is one of the few lichens, which is favoured by eutrophication, it is very common on rocks, large trees, roofs, walls, etc.

The specific name parietina, from the Latin paries (‘wall’), was applied by Swedish naturalist Carolus Linnaeus (1707-1778), also called Carl von Linné, in 1753.

Orange milkwort (Polygala lutea) is found in eastern United States, from southern Maine southwards to Florida, and thence westwards to Louisiana. It is especially common in the Pine Barrens of New Jersey. The specific name is Latin for ‘yellow’, referring to the distinctive colour of the flowers when dried. When fresh, they are bright orange, differing from most other milkworts, which have blue, pinkish, or white flowers.

Common lantana (Lantana camara), also called a number of other names, including feston rose plant, Westindian lantana, and Spanish flag, is a small shrub of the vervain family (Verbenaceae), which can grow to a height of about 2 m. The inflorescences come in many different colours, including red, orange, yellow, pink, or white, often several colours in a single inflorescence.

This plant is native to the American tropics, but due to its pretty flowers it has been introduced almost worldwide. In warmer countries, it often escapes, and as it is toxic to grazing animals, it often forms large thickets, out-competing natural vegetation.

Two of the colour forms of this plant, red and yellow, has given rise to the popular name Spanish flag, due to the similarity of these colours to the ones in the Spanish national flag.

Lychee (Litchi chinensis) is a tropical tree, which is native to south-eastern China, where it has been cultivated as far back as the 11th Century. However, due to the sweet flesh of its fruit, it is cultivated in many other places, including Southeast Asia, India, and South Africa. It is the sole member of the genus Litchi, which belongs to the soapberry family (Sapindaceae).

The gorgeous white waterlily (Nymphaea alba) has a very wide distribution, found in Europe, North Africa, the Middle East, and parts of Temperate Asia, eastwards to Kashmir, northern India. In America, it is replaced by the very similar fragrant waterlily (N. odorata), which is also widely distributed, from northern Canada through the United States, Mexico, and Central America to northern South America.

A picture, depicting blue waterlily (N. caerulea) is shown on the page In praise of the colour blue.

Usually, the leaves of white waterlily are various shades of green, but for some reason this leaf in a pond on the island of Fanø, Denmark, has turned orange-yellow. The pond is filled with a yellowish species of alga. The green stems in the foreground are common spike-rush (Eleocharis palustris).

The orange weaver ant (Oecophylla smaragdina) has a wide distribution, found in India, Southeast Asia, the Philippines, Indonesia, and northern Australia.

The name weaver ant stems from their nest, which is made by ‘weaving’ together leaves, using larval silk. A colony of these ants may include several nests in a single tree, or the nests may be spread over several adjacent trees. In one instance, a colony occupied 151 nests, distributed among 12 trees. A colony may count up to half a million individuals. Each colony has a single queen in one nest, from which her progeny is carried to other nests. (Source: en.wikipedia.org/wiki/Oecophylla_smaragdina, with a list of references)

Popular names of Leonotis nepetifolia, a member of the mint family (Lamiaceae), include Christmas candlestick and lion’s ear. This plant is native to tropical Africa, the Indian Subcontinent, and parts of Indochina. It has been introduced elsewhere and has escaped in many places, especially Latin America and the West Indies.

The inflorescences are whorls of pretty, orange flowers, arranged up the stem, which may grow to 3 m tall. Occasionally, plants with red, white, or purple flowers may be encountered.

In Trinidad, the leaves are brewed as tea for treatment of fever, coughs, womb prolapse, and malaria.

The pictures below were taken in Bagan, Myanmar. A Buddhist pagoda is seen as a silhouette in one of the pictures, and the bird in the upper picture is a male purple sunbird (Cinnyris asiaticus), sucking nectar from the flowers. Other pictures, depicting this bird, are presented on the page Animals – Birds: Birds in Bagan.

Hawk’s-beard (Crepis) constitute a huge genus, comprising about 200 species, distributed in the Northern Hemisphere and Africa, with a core area around the Mediterranean. The generic name is derived from the Greek krepis (‘slipper’ or ‘sandal’), according to some authorities referring to the shape of the fruit.

In my opinion, the most beautiful member of this genus is golden hawk’s-beard (C. aurea), which is distributed in European mountains, in the Jura, the Alps, the Apennines, the Abruzzos, and on the Balkans, and it is also found in Asia Minor. In the Alps, it grows in meadows and pastures, preferably on acid soil, at altitudes between 1,000 and 2,900 m.

The picture below shows a sculpture in the Pashupatinath Temple, Kathmandu, Nepal, depicting the elephant-headed Hindu god Ganesh. The features of the image have become blurred due to a thick layer of orange sindur (red powder, mixed with mustard oil), applied by devout Hindus over the centuries.

Ganesh and other Hindu gods are presented in depth on the page Religion: Hinduism.

California sister (Adelpha californica) is a butterfly of the brushfoot family (Nymphalidae), distributed from Oregon and Nevada southwards through California to northern Baja California. It is easily identified by the orange or yellow patch near the wingtip.

Lotus is a huge genus of the pea family (Fabaceae), comprising at least 130 species. The popular name of these plants is bird’s-foot trefoil, the trefoil part referring to the tripartite leaves, whereas bird’s-foot refers to the often triple pods, which spread out from a common point, hereby resembling a bird’s foot.

Common bird’s-foot trefoil (Lotus corniculatus) is widely distributed in Temperate Eurasia, growing in drier habitats with low vegetation. In the Himalaya, it is found between 1,500 and 4,000 m altitude, from Pakistan east to central Nepal.

Following genetic studies, a group of thrushes, encompassing about 21 species, which were traditionally placed in the genus Zoothera, were moved to the genus Geokichla in 2008. This genus was established in 1836 by German naturalist Salomon Müller (1804-1864), who explored parts of Dutch East Indies (today Indonesia) between 1826 and 1835.

The generic name is from the Greek geo (‘ground’) and kikhle (‘thrush’), referring to the almost exclusively ground-feeding habit of these birds.

Altogether 11 subspecies of the pretty orange-headed ground-thrush (Geokichla citrina) are distributed along the Himalaya, in eastern and Southern India, on the Andaman and Nicobar Islands, in Indochina, southern and eastern China, and northern Borneo, and on Java and Bali. It is resident in the major part of this huge area, but some northern populations are migratory, spending the winter in north-eastern and southern India, Sri Lanka, Sumatra, and southern China.

Subspecies cyanota of southern India is very distinct, having a white face with two vertical black streaks below and behind the eye. It has been suggested that it forms a separate species, but intermediate forms occur where its range overlaps with that of nominate citrina.

Previously, it was assumed that slime mold (Mycetozoa) were a type of fungi. Today, however, most authorities regard them as partly plants, partly animals, as they are able to creep about in their young stage.

As its name implies, the coast hibiscus (Hibiscus tiliaceus) is mainly coastal, but it may be found up to an altitude of 300 m. It is native to islands in the Pacific and Indian Oceans, coastal Australia, Indonesia, Southeast Asia, the Indian Subcontinent, southern China, and Taiwan, but has also become naturalized elsewhere in tropical parts of the world.

The specific name was given in allusion to its leaves, which resemble leaves of linden species (Tilia). A picture, depicting the gorgeous yellow flowers, is shown on the page In praise of the colour yellow.

Horned poppies (Glaucium) are named for their horn-shaped fruits. The flower colour of the red horned poppy (G. corniculatum), which is distributed from southern Europe eastwards to Central Asia, varies from dark red to dark orange.

Many more poppy species are described on the pages In praise of the colour red and In praise of the colour yellow.

The orange-peel fungus (Aleuria aurantia), of the family Pyronemataceae, grows on bare soil. It is distributed throughout Europe, and in parts of Asia and North America, and has also been found in southern Chile.

The common name stems from its brilliantly orange, cup-shaped ascocarps, which often resemble orange peels, strewn on the ground. The specific name, from the Latin aurantia (‘orange’) was applied in 1800 by mycologist Christiaan Hendrik Persoon (1761-1836), who was born in South Africa, but moved to Europe in his twenties.
