Leopoldia tenuiflora

Description

Leopoldia is a genus of bulbous perennial plants in the family Asparagaceae, subfamily Scilloideae. The genus is widespread around the Mediterranean region and neighboring lands, from the Canary Islands to Iran. Leopoldia species were formerly included in the genus Muscari (as the Leopoldia group or subgenus), and like muscari are often called grape hyacinths. Their flowers are arranged in a spike or raceme with those at the top more brightly coloured than those lower down. Leopoldia can be distinguished from Muscari by being generally taller plants and having more open spikes or racemes of flowers, caused by the individual flowers being spaced further apart. The lower fertile flowers are relatively long, often urn-shaped or tubular and are white, yellow, green or brown but never blue; they have distinct 'shoulders' close to the mouth of the flower, which is smaller than the general diameter of the flower and surrounded by small lobes or "teeth" formed by the ends of the fused tepals. The colour of the lobes is a diagnostic feature in identifying species. At the top of the raceme there is usually a tuft of bright violet, blue or pink sterile flowers. In 1819, William Herbert was the first to use Leopoldia as the name of a genus; it was proposed as a provisional name (nomen provisorium) for the genus he later (in 1821) called Hippeastrum. Although Leopoldia was subsequently validated (i.e. it became the correct name for Hippeastrum), this was overlooked, and Hippeastrum rather than Leopoldia was used for the genus of New World amaryllids. In 1845, Filippo Parlatore independently proposed Leopoldia for a group of species he separated from Muscari. In 1970, Fabio Garbari and Werner Greuter proposed that Parlatore's Leopoldia should be conserved and Herbert's Leopoldia rejected. This was accepted and Leopoldia Parl. is now a conserved name (nomen conservandum), and so the correct name for the genus described here.
