Huernia
Huernia thuretii
The plant genus Huernia belongs to the subfamily of milkweed plants ( Asclepiadoideae ) within the family of the dogbane family ( Apocynaceae ). For the Huernia types of German trivial name is used as carrion flowers in species of many other genera of the subtribes Stapeliinae.
Description
Huernia species are succulent plants; usually they make stocks. The stems are low or but rarely more than 10 cm high, by reason of, rare highly branched, four -to six- edged, mostly with large edge and usually with big teeth, more or less gray-green, often flushed, always bare. Are formed only rudimentary leaves, but no stipules.
Inflorescences and flowers
Short -stalked, doldige inflorescences form with lanceolate bracts and the unfolding one after the flowers at the base of the stems. The flower stems are relatively short.
The hermaphrodite flowers are radial symmetry and fünfzählig. The five ovate - lanceolate sepals are fused and end with five pointed lobes. The five petals are fused bell-shaped at the base and end with a zehnzipfeligen hem, ie, each with a smaller tip in the bays of the five larger. The tip of the bud are klappig that Mittelzipfelchen form projecting corners. There is a double row Corona, each provided with five lobes and is usually inside papillose or warty, rarely smooth. The outer corona is absent in one species and is the Blütengrund or is even slightly grown and attached to the base of the Gynostegiums; the sections ( ligules ) are more or less free or fused, more or less rectangular, incised or toothed, usually very dark in color. Portions of the inner corona, the Staminalsäule and the anthers grown, just as long or longer than the anthers. The club-shaped pollinia possess at Klemmkörperchen two lateral appendages.
Fruit and seeds
The upright follicles are bald. The seeds have a tuft of hair on their head.
Dissemination
The natural distribution of the genus Huernia extends over South Africa and Namibia, the species are so Flore elements of the capensis; Ethiopia and the Arabian Peninsula.
System
The first description of the genus Huernia was made in 1810 by Robert Brown. The genus name Huernia based on a clerical error and refers to the Dutch missionary Justus Heurnius (1587-1652), who collected the first Europeans at the Cape of Good Hope plants.
