Tongariro National Park is situated in the southern part of the North Island of New Zealand, centered around three active volcanoes, Ruapehu (2797 m), Ngauruhoe (2291 m), and Tongariro (1978 m). This park, which covers 786 km2, was established as early as 1887, thus being among the oldest national parks in the world. For the major part of the year, the higher areas of the park are covered in snow.

In fact, Ruapehu is a name that includes a number of peaks, of which the tallest is Tahurangi (2797 m), whereas a striking pointed peak is Girdlestone (2658 m). Initially, this mountain was named Little Matterhorn Peak by Hubert Earle Girdlestone (1879-1918), a New Zealand explorer and war hero, who was killed in France in 1918. His friends installed a plaque on the mountain in 1922, renaming it Girdlestone Peak.

The giant taro, or giant elephant’s ear (Alocasia macrorrhizos), which grows to a height of 5 m, is native from Malaysia south through Indonesia to northern Australia, but has been introduced to many other tropical and subtropical areas as an ornamental, food crop, or animal feed. It is listed as an invasive species in Cuba, New Zealand, and several Pacific islands.

The gigantic leaves of this plant are often used as umbrellas. Its rhizome is edible when cooked for a long time, but the sap irritates the skin in your mouth, as it contains needle-like calcium oxalate crystals. In Hawaii, this plant is called ʻape, and they have a saying, Ai no i ka ʻape he maneʻo no ka nuku. (’The one who eats ʻape, will have an itchy mouth’), meaning ’There will be consequences for partaking of something bad.’ (Sources: S. Scott & T. Craig, 2009. Poisonous Plants of Paradise: First Aid and Medical Treatment of Injuries from Hawaii’s Plants. University of Hawaii Press; and M.K. Pukui, 1986. ‘Ōlelo No’eau, Hawaiian Proverbs and Sayings. Bishop Museum Press, Honolulu.)

In many areas around the Earth, cone-shaped pillars are formed in volcanic layers, or in moraine clay or gravel, which was deposited during the last Ice Age. In dry weather, these layers are hard as stone, but when it rains, it becomes softer and begins to erode away. However, larger rocks were also deposited by the volcanoes and the glaciers, and under such stones the soil is protected from the rain. Over the years, the surrounding soil is eroded away, and beneath the rocks majestic pillars are formed, often rising steeply out of the soil. Such structures are called earth pyramids.

The genus Artocarpus, popularly called breadfruit, of the fig family (Moraceae), contains about 60 species of trees and shrubs, most of which are indigenous to Southeast Asia, a few to the Pacific. The numerous flowers grow into a so-called syncarpous fruit, i.e. a fruit with numerous carpels, packed closely together. In many species, the fruit can grow to a very large size.

The generic name is derived from the Greek artos (‘bread’) and karpos (‘fruit’), a name given by Scottish-German botanist Johann Reinhold Forster (1729-1798) and his son Johann Georg Forster (1754-1794), who participated as botanists during the second voyage of James Cook (1728-1779), which took place 1772-1775.

Breadfruit (Artocarpus altilis) is thought to be a domesticated form of A. camansi, which is native to New Guinea, the Maluku Islands, and the Philippines. At an early stage, this cultivar was introduced to islands in the Pacific, where British botanist Sir Joseph Banks (1743-1820), who participated as a botanist in James Cook’s first expedition (1768-1771), first encountered it in Tahiti and quickly realized its value as food. British plantation owners in the Caribbean now saw a possibility of getting access to a highly productive and nutritious food for their slaves, and they eagerly supported Banks in his endeavour to persuade the British Government to send a ship to Tahiti with the aim of bringing live breadfruit plants to the Caribbean. In 1787, HMS Bounty left England with William Bligh as captain.

In Tahiti, breadfruit plants were collected with success, but shortly after leaving the islands, the crew carried out the later so famous mutiny, put Blight and a few loyal crew members in a launch, and then sailed towards the east, where they founded a village on the island of Pitcairn. Against all odds, Bligh and his crew managed to reach the Dutch East Indies (today Indonesia), and in 1791, Bligh led a new expedition to Tahiti, from where breadfruit plants were transported to the Caribbean. However, all efforts were in vain, as the large majority of the slaves refused to eat the new food.

The native range of snowball sand verbena (Abronia fragrans) is the American prairie states, from Montana and North Dakota southwards to Arizona, Texas, and Chihuahua, northern Mexico. Despite its name, it is not related to the common vervain (Verbena officinalis), but is a member of the four-o’clock family (Nyctaginaceae).

This species was first collected by Thomas Nuttall (1786-1859) near the Platte River, Nebraska. He was a British printer, who came to the U.S. in 1808. Shortly after his arrival, he met botanist Benjamin Barton (1766-1815), who induced a strong interest in natural history in him. During the following years, until 1841, Nuttall undertook several expeditions in America, and numerous plants and animals are named after him.

The greater plantain (Plantago major) is native to Europe and Temperate Asia, but has been introduced to many parts of the world, often becoming naturalized. When the Europeans emigrated to North America, this species was inadvertently brought along. Its sticky seeds would often stick to wagon wheels of the settlers, who thus spread it wherever they went. This was noticed by the indigenous peoples, who called it ‘white man’s footprint’.

The vast Thar Desert stretches across the state of Rajasthan, north-western India, and further west into Pakistan. The main part of this desert is level sand or gravel plains with scattered bushes and trees, such as dzal (Salvadora procera), thor (Euphorbia caduca), which is a cactus-like species of spurge, and Sodom apple (Calotropis procera), locally called akaro.

The fruit of Sodom apple was first described by Roman historian Titus Flavius Josephus, born Yosef ben Matityahu (c. 37-100 A.D.), who found it growing near the city of Sodom: “which fruits have a color as if they were fit to be eaten, but if you pluck them with your hands, they dissolve into smoke and ashes.” (W. Whiston, 1737. The War of the Jews, Book IV, Chapter 8, Sec. 4). Titus is referring to the fact that the ripe fruit easily dissolves, releasing hundreds of downy seeds, which are scattered to the four winds.

The city of Jaisalmer is situated in the heart of the Thar Desert, near the Pakistani border. It was founded in 1155 by Rajput prince Roa Rawal Jaisal, who ordered construction of a huge fort, Sonar Qila – testimony of a time, when unrest reigned in this area. Originally, this fort was surrounded by an outer wall, 4.5 km long, but today the city stretches far beyond the remains of this wall.

This interesting area is described in depth on the pages Travel episodes – India 1986: “Sir, would you like to see this peacock?” and India 2003: Camel safari in the Thar Desert.

The marram grass (Ammophila arenaria) is native to coastal sand dunes of Europe and North Africa. It is very proliferous, as its rhizomes can grow 2 m in about six months, and one clone can produce a hundred new shoots annually. This grass was introduced to western North America in the mid-1800s to stabilize shifting sand dunes. However, it soon spread beyond control, and today it is one of the worst invasive weeds of coastal California, which has spread northwards to British Columbia. (Source:

The sacred, or Indian, lotus (Nelumbo nucifera) is distributed from Iran and the entire Indian Subcontinent, eastwards to southern China, Taiwan, and Japan, thence south through Southeast Asia, Malaysia, and Indonesia to New Guinea and northern Australia. All parts of this plant are edible, in particular the rhizome and seeds. Rhizome, leaves, and seeds are also widely used in traditional Indian and Oriental medicine for treatment of numerous ailments. The plant is sacred to Hindus, Buddhists, Sikhs, and Jains, who call it padma.

The important role of the lotus in Buddhism and Hinduism is described on the page Plants: Plants in folklore and poetry, whereas the various Indian religions are dealt with on the page Religion.

Humayun, whose real name was Nasir-ud-Din Muḥammad, was the second emperor of the Moghul Empire, comprising what is today north-western India, Pakistan, and Afghanistan. Humayun ruled in two periods, 1531-1540 and 1555-1556. He died in 1556, when he stumbled on the staircase, leading up to his library, hitting his head on the rough stone steps.

Popular names of the genus Heliconia include lobster-claw, toucan beak, wild plantain, and false bird-of-paradise. Formerly, this genus, comprising about 200 species, was included in the banana family (Musaceae), but is now forming a family of its own, Heliconiaceae. These plants are found mainly in Central and South America, with a few species in some Pacific Islands and Indonesia.

The origin of peacock-plume grass (Chloris barbata), also called purple top or swollen fingergrass, is uncertain. Some authorities maintain that it is native to Tropical America, others claim that it is indigenous in Tropical Africa. Whatever its origin may be, it has been accidentally introduced to most warmer parts of the world and is regarded as an invasive in a number of countries, including Australia, Korea, Thailand, Cambodia, and India.

This species is a common weed in sugarcane and rice fields, which is a serious problem, as it is a host of a number of rice insect pests, including white-backed planthoppers (Sogatella furcifera and Sogatodes pusanus), rice bug (Leptocorisa oratorius), rice ear-cutting caterpillar (Mythimna separata), cereal thrips (Haplothrips ganglbaurei and Chirothrips mexicanus), and others.

Udaipur is a delightful city in southern Rajasthan, India, situated around the gorgeous Pichola Lake. As early as the 10th Century, the Hindu Mewar Rajputs established a town here, named Ayad, which became a thriving trading centre.

During the 1550s, Maharana Udai Singh II was the ruler of Chittorgarh, a city situated a little further north in a flat tableland, which, however, was vulnerable to attacks from the Maharana’s enemies, notably Muslims, who had conquered parts of northern India. Following the emergence of artillery warfare, Udai Singh, in 1559, decided to move his capital to a more secure location, choosing Ayad. However, as Ayad was prone to flooding, he chose to establish his new capital on a ridge east of the Pichola Lake. To protect the new city from attacks, Udai Singh ordered a 6-km-long wall, with seven gates, to be erected around the city.

The belligerent Rajputs are described in detail on the page Travel episodes – India 1986: “His name is Muhammed!”

The scientific family name of squirrels, Sciuridae, is derived from Sciurus, the name given in 1758 to the Eurasian red squirrel by Swedish naturalist Carolus Linnaeus (1707-1778), also called Carl von Linné. Sciurus is a Latinized form of the Greek word skiouros, meaning ‘shadow-tailed’, from skia (‘shadow’) and oura (‘tail’).

Many species of squirrel are presented on the page Animals: Squirrels of North America.

The Jelling Stones near Jelling Church, Jutland, Denmark, are runic stones, dating back to c. 965 A.D. The larger stone was erected by King Harald ‘Bluetooth’ to commemorate his parents, King Gorm and Queen Thyra. On one side of the stone is a carving of Christ – the oldest Norse image of Christ – and on the other an animal, entwined by a serpent. The text translates as follows: “King Harald ordered these runes carved to commemorate Gorm, his father, and Thyra, his mother – the very Harald who conquered all of Denmark and Norway, and Christened the Danes.”

The smaller stone, which was erected by King Gorm, says: “King Gorm made these runes to commemorate Thyre, his wife, Denmark’s pride.”

Today, unfortunately, the stones are behind armoured plastic, partly because they had been subject to vandalism, partly because they were beginning to show signs of erosion from acid rain.

The fragrant taro, or lesser elephant-ear (Alocasia odora) is native from north-eastern India eastwards to Japan, and thence southwards to Borneo. In Vietnam, this herb is used for treatment of colds. The plant is inedible when raw because of needle-sharp calcium oxalate crystals in its cells. In Japan, several cases of food poisoning by consumption of this plant have been reported.

Creosote (Larrea tridentata) is a shrub, which can grow in the most extreme desert conditions. Today, it is distributed over hundreds of thousands of km2 in the Mohave, Sonora and Chihuahua Deserts in south-western United States and Mexico. This species is protected against extreme heat and drought by a layer of insulating resin, which has a foul smell, hence the Mexican folk name hediondilla (’the little stinker’). It also tastes horribly, containing chemical substances like flavin, lignin, and saponin.

Creosote is an extremely hardy plant. Following nuclear tests in the Nevadan desert in 1962, all living things, naturally, had been split to atoms. Ten years later, however, 20 of the original 21 creosote bushes had sprouted again!

The oldest living organism in the world is thought to be a creosote clone in the Mohave Desert, estimated to be c. 9,400 years old.

Field bindweed (Convolvulus arvensis) is a Eurasian species, which twines around other plants to compete for sunlight and nutrients.

In America, popular names of this species include Creeping Jenny and many others, alluding to its invasive nature. In his delightful book All about Weeds, American botanist Edwin Spencer (1881-1964) writes: “Creeping Jenny is one of the meanest of weeds. That name aptly describes it. A whispering little hussy that creeps in and spoils everything. The weed needs no other name than this, but it has several others (…) hedge bells, corn-lily, withwind, bellbine, lap-love, sheep-bine, corn-bind, bear-bind, and green vine.”

Many other members of the morning-glory family are presented on the page Plants: Morning-glories and bindweeds.
