Many species previously classified in Androcymbium, Bulbocodium and Merendera were moved to Colchicum based on molecular genetic evidence. The following are the species included in the genus Colchicum. The species known to contain the most lethal amount of colchicine is C. Murderer Catherine Wilson is thought to have used it to poison a number of victims in the 19th century. Its leaves, corm and seeds are poisonous. The use of the roots and seeds in traditional medicine is thought to have arisen due to the presence of this drug. Plants in this genus contain toxic amounts of the alkaloid colchicine which is used pharmaceutically to treat gout and Familial Mediterranean fever. In the United Kingdom, the National Collection of colchicums is maintained at Felbrigg Hall, Norfolk. Those marked agm have gained the Royal Horticultural Society's Award of Garden Merit (confirmed 2017). 'Dick Trotter' (violet with white centre) Temperate colchicums are commonly grown in gardens as ornamental flowers. Close relatives such as Colchicum scabromarginatum ( Androcymbium scabromarginatum) and Colchicum coloratum ( Androcymbium burchellii) have flowers with very short stalks and may be pollinated by rodents. In contrast to most temperate colchicums, the flower and leaves are produced at the same time, the white flowers usually in a small corymb that is enclosed by white bracts. Relationships Ĭolchicum melanthioides, also known as Androcymbium melanthioides, is probably the best known species from the tropical regions. The Greek toponym Colchis is thought by scholars to derive from the Urartian Qulḫa, pronounced "Kolcha" (guttural "ch" - as in Scots loch). Colchis features in Greek mythology as the land to which the Argonauts journeyed in quest of the golden fleece and where Jason encountered Medea. The name of the genus derives from Κολχίς ( Colchis), the Ancient Greek name for the region of კოლხეთი ( Kolkhida) in modern Georgia ( Caucasus). In addition, the corm structures are quite different-in Colchicum, the corm is irregular, while in crocuses, the corm is like a flattened ball. ![]() However, colchicums have 3 styles and 6 stamens, while crocuses have 1 style and 3 stamens. To add to the confusion, there are autumn-flowering species of crocus. The common names autumn crocus, meadow saffron and naked lady may be applied to the whole genus or to many of its species they refer to the "naked" crocus-like flowers that appear in late summer or autumn, long before the strap-like foliage which appears in spring.Ĭolchicum and Crocus look alike and can be confused by the casual observer. As a consequence, the styles are extremely long in proportion, often more than 10 cm (4 in). In this genus, the ovary of the flower is underground. It is a member of the botanical family Colchicaceae, and is native to West Asia, Europe, parts of the Mediterranean coast, down the East African coast to South Africa and the Western Cape. inval.Ĭolchicum ( / ˈ k ɒ l tʃ ɪ k əm/ KOL-chik-əm or / ˈ k ɒ l k ɪ k əm/ KOL-kik-əm) is a genus of perennial flowering plants containing around 160 species which grow from bulb-like corms. For the daffodil, see Narcissus bulbocodium. ![]()
