In praise of the colour violet

 

 

 

 

 

 

 

 

 

 

 

 

 

Today, this plant is cultivated in temperate areas around the world. In the wild, it is found from central Europe and the Mediterranean eastwards to Kazakhstan and Iran. Its flower colour is usually bluish-violet, but a form with white flowers is also common.

The genus Viola contains no less than 550-600 species, and members are found almost worldwide, with the highest diversity in temperate regions of the Northern Hemisphere. The flowers have 5 very unequal petals, the lower one larger and spurred. The fruit is a capsule, splitting along 3 seams.

Flowers of most wild violets are various shades of violet or blue, but white and yellow flowers are also common (see pages In praise of the colour blue and In praise of the colour yellow). Many species are popular garden plants, often called pansies. This name is explained on the page Plants: Plants in folklore and poetry.

 

 

 

 

 

The specific name is derived from the Latin cucullus (‘hood’) and the suffix atus (‘having a beard’), presumably alluding to the white tuft of hairs in the mouth of the flower.

 

 

 

 

 

This plant is found in the Alps, from France eastwards to Slovenia, and also on the Balkan Peninsula, southwards to Macedonia. It grows in grassy areas at altitudes between 1,500 and 2,800 m.

The specific name is Latin, meaning ‘having a spur’, alluding to the long spur of this species.

 

 

 

 

 

 

 

 

 

 

This plant was named in honour of Danish physician and botanist Nathaniel Wallich (1786-1854), who studied the Indian and Himalayan flora in the early 1800s.

 

 

 

 

 

It grows at elevations between 3,000 and 5,000 m, from the Chinese provinces Gansu and Qinghai southwards across Tibet to Pakistan, and thence eastwards to south-western China.

 

 

 

 

 

The name is of Tupi-Guarani origin, meaning ‘fragrant’. This name was adopted by the Portuguese.

 

 

 

 

 

Members of this genus are usually called scabious, although, strictly speaking, that name is reserved for a closely related genus, Scabiosa. Species of scabious were once utilized to treat scabies and other skin problems, hence the name. The word is derived from the Latin scabere (‘to scratch’).

The generic name was applied by Swedish botanist Carl Linnaeus (1707-1778) in honour of two German brothers, Christoph Knaut (1638-1694) and Christian Knaut (1656-1716), both botanists and physicians. The latter published Compendium Botanicum sive Methodus Plantarum Genuina, in which he provided a classification system for flowering plants, based on petal number and arrangement.

Previously, these plants were placed in the scabious family (Dipsacaceae), but this family has been reduced to a subfamily, Dipsacoideae, within the honeysuckle family (Caprifoliaceae). The flowers are densely clustered in a terminal head, resembling composites of the family Asteraceae.

 

The specific name is Latin, meaning ‘growing in fields’, derived from arvus (‘cultivated land’).

 

 

 

 

 

The specific name is Latin, meaning ‘with leaves like Dipsacus‘ (teasel).

 

 

 

 

 

 

 

 

 

 

The specific name is Latin, meaning ‘ash-coloured’. What it refers to is not clear.

 

 

 

 

 

 

 

 

 

 

Young pods and seeds are edible and were formerly consumed by various North American indigenous peoples. In his book Cape Cod (1865), American author Henry David Thoreau (1817-1862) quotes that “in 1555, during a time of great scarcity, the people about Orford in Sussex, England, were preserved by eating the seeds of this plant, which grew there in great abundance on the sea-coast.”

However, the seeds contain a toxic amino-acid, which can cause lathyrism (muscle wasting), if consumed in large quantities. The leaves are used in Chinese traditional medicine.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Despite its name, the New England aster (Symphyotrichum novae-angliae) is widely distributed, found in south-eastern Canada and the major part of the United States, except the south-western states. It is a robust plant, which may grow to 1.2 m tall. The flowerheads have numerous ray florets, sometimes up to 100, which are normally deep purple, occasionally pink or white. The likewise numerous disc florets are yellow or orange, turning brownish with age.

 

 

 

 

 

 

 

 

 

 

The specific name is derived from the Latin uligo (‘dampness’), referring to the fact that the prime habitat of this species is swampy areas.

 

 

 

 

 

The tuberous vervain (Verbena rigida), also called slender vervain, is native to South America, from Bolivia and south-eastern Brazil southwards to northern Argentina. Elsewhere, it is a popular garden plant, which has become naturalized in numerous warmer areas around the world. The popular name alludes to its undergrond tuber.

 

 

 

 

 

The whole plant contains the alkaloid colchicine, with the highest concentrations in the leaves, which deters herbivores from eating them.

It is widespread in the Iberian Peninsula, northwards to the Pyrenees, where it may be found up to an elevation of about 2,600 m. It is abundant in pasture lands, flourishing along roads and trails, often in dry and stony places. The highest density is found in highly disturbed areas with large populations of a species of vole, Microtus duodecimcostatus. Research suggests a symbiotic relationship between the two: the voles feed on the much less toxic rhizomes, which activates asexual reproduction processes. This mechanism is not observed in undisturbed pastures. (Source: D. Gómez et al. 2003. Seasonal and spatial variations of alkaloids in Merendera montana in relation to chemical defense and phenology. J. Chemical Ecol. 29 (5): 1117-1126)

 

 

 

 

 

The stipules (leaf-like appendices at the base of leaves) are often distinct on these plants. After flowering, the style forms a long, straight or up-curved beak, which separates into 5 elastic spring-like coils, each containing a single seed that is expelled, usually when the style is touched.

The generic name is derived from the Greek geranos (‘crane’), alluding to the fruit, whose shape resembles a crane’s bill.

 

The specific name means ‘growing in woods’, derived from the Latin silva (‘forest’).

 

 

 

 

 

 

 

 

 

 

 

 

Stem, leaves, and flower stalks are covered with sticky hairs, and research has shown that the plant is able to absorb protein from insects that get stuck in these hairs.

Formerly, members of the Niitsitapi peoples (‘Blackfeet’) used an infusion from this plant to treat diarrhoea and other gastric problems, and also urinary trouble. The root was dried and powdered and then used to stop external bleeding. An infusion of the leaves was used to treat colds and sore throat.

 

 

 

 

 

 

 

 

 

 

The generic name is derived from the Greek melampyron, of melas (‘black’) and pyros (‘wheat’), referring to the black seeds, which somewhat resemble wheat grains. An ancient belief had it that the seeds, when mixed with wheat and ground into flour, tended to make the bread black. In the Middle Ages, it was also believed that the seeds were capable of being converted into wheat, supposedly because of the sudden appearance of these plants among wheat, planted on recently cleared land. Cows and sheep readily eat these plants, hence the name cow-wheat. (Source: M. Grieve, 1931. A Modern Herbal. Jonathan Cape, here from botanical.com)

In his Cruydeboeck (herb book), Flemish physician and botanist Rembert Dodoens (1517-1585) tells us that “the seeds of this herb taken in meate or drinke troubleth the braynes, causing headache and drunkennesse.”

Wood cow-wheat (M. nemorosum) mainly grows in eastern Europe, found from Denmark, Germany, and Italy eastwards to north-western Russia.

Popular names include the Swedish natt-och-dag (‘night-and-day’) and the Russian Ivan-da-Marya (‘Ivan-and-Maria’), both names referring to its striking inflorescences, with yellow flowers and bright purplish-violet bracts.

 

 

 

 

 

Botanically, the pineapple is an herb, which may grow to 1.5 m tall, sometimes taller. It has a short, stocky stem with tough, waxy, spiny leaves, growing to 1 m long. It produces up to 200 bluish-violet flowers, in cultivation sometimes more. In the wild state, it is pollinated primarily by hummingbirds, sometimes at night by bats. The individual fruits, which are berries, join together to create a multiple fruit, the ‘pineapple’.

The English name stems from 1568, from the book Les singularitez de la France antarctique (1557), written by French priest, explorer, and writer André Thevet (1516-1590), relating his experiences in France Antarctique, a French settlement near present-day Rio de Janeiro. In English, this book is titled The New Found World, or Antarctike. Thevet refers to a fruit, cultivated and eaten by the Tupinambá people, living in this area. He describes the fruit as nanas, a Tupi word meaning ‘excellent fruit’, and says that it was made in the manner of a ‘pine apple’ (pine cone). (Source: en.wikipedia.org/wiki/Pineapple)

The Tupi word was adopted by Scottish botanist Philip Miller (1691-1771) as the plant’s generic name in the form Ananas, whereas the specific name is Latin, derived from coma, which literally means ‘hair’, but is also used as a term for leaves, thus ‘with many leaves’.

 

 

 

 

 

 

 

 

 

 

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. The popular name is a corruption of an ancient Germanic name of these plants, Nachtschatten, of unknown meaning. As Schatten also means ‘shadow’ in German, the name nightshade was introduced, but apparently this is a misnomer.

 

The specific name is Latin, meaning ‘without tubers’.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It grows on calcareous soils in open forests, shrubberies, dry grasslands, and sometimes along roads and trails. It is native to northern temperate areas of Eurasia, from almost all of Europe eastwards to the Pacific, southwards to Spain, Turkey, Iran, the Himalaya, northern China, and Japan. It has also become naturalized in North America.

The specific name is Latin, meaning ‘gathered in a group’, referring to the dense inflorescence. An old folk name is Dane’s blood, alluding to the fancy belief that this plant sprouted in places, where Danes had been slain in battle.

Astragalus onobrychis is usually a prostrate plant, forming dense growths to 30 cm tall, occasionally to 60 cm. It is native from the western Alps eastwards to western Siberia and the Altai Mountains, southwards to the Mediterranean, the Caucasus, and northern Iran. It was originally a steppe plant, which has adapted to grassy areas in mountains.

The specific name alludes to the similarity of the flowers to those of the genus Onobrychis.

 

 

 

 

 

The common names allude to the leaves being almost all basal.

 

 

 

 

 

The generic name is derived from the Greek hormao (‘to hasten’), referring to the uasge of this herb as an aphrodisiac. The common name refers to the gaping corolla.

 

 

 

 

 

The generic name is from the Latin pulsare (’to beat’), referring to the flowers, which move back and forth in the wind. The word pasque is from the Latin pascha, a corruption of the Ancient Greek páskh, which was ultimately from the Hebrew pésakh (‘Passover’). This one-day feast begins on the 14th day of the first month, followed by the seven-day Feast of Unleavened Bread. In Christianity, pasque is an old expression for Easter. The name pasque flower refers to the early flowering of several species, often coinciding with Easter.

The role of these plants in traditional medicine and folklore is described on the page Plants: Anemones and pasque flowers.

 

 

 

 

 

 

This species is distributed from the western Alps eastwards to the Carpathians and mountains on the Balkan Peninsula, growing on dry calcareous soils, from the lower valleys up to altitudes of about 2,000 m.

 

 

 

 

 

It comes in two varieties, var. patens of Europe and western Siberia, and var. multifida of eastern Siberia and North America. The former is highly threatened in Finland due to former over-collecting, and the latter is declining in America due to increased cultivation of prairies.
