Genlisea subglabra
Flowering Genlisea subglabra
Genlisea subglabra is a carnivorous plant species of the genus Reuse traps in the family of water hose plants ( Lentibulariaceae ). It is native to central Africa.
Description
Genlisea subglabra is a perennial, herbaceous plant. The bare, spatulate and obtuse at the end leaves are in a dense basal rosette, are 1-5 inches long and 8-9 mm wide. Numerous cases reach lengths of up to 10 centimeters.
The upright, simple or weakly branched inflorescence axis is 10 to 30 (rarely to 70) cm high, in cross-section cylindrical, glabrous in the upper part, slightly to densely occupied in the lower part with nichtdrüsigen, standing in rows bristles, and also found a few scale leaves which are similar to the bracts. These are ovate - lanceolate to linear - lanceolate, tapering to a point and reach a length of 2 to 4 millimeters, the bracteoles are lanceolate and shorter.
At the inflorescence are rarely just one, usually three to ten, rarely up to fifteen flowers on erect, 5-15 (20 ) mm long, during flowering and fruit -growing and continue to bare bristly flower stems.
The calyx is five-lobed and divided to approximately the approach, the individual lobes are approximately the same shape, ovate - lanceolate to lanceolate, tapering to a point and 2 to 4 mm long and either bare or covered with short glandular hairs and bristles nichtdrüsigen. The crown is 10 to 15 millimeters long, their coloration is variable, the colors range from blue to purple and violet to pink, the spur, however, falls from greenish to yellowish. The up to 5 mm long and 4 mm wide upper lip is oblong - ovate round, is busy on the outer part with nichtdrüsigen bristles and tapers towards the top, trimmed end. The significantly dreigelappte lower lip is up to 9 millimeters long and 10 millimeters wide. The oblong- round, blunt spur is occupied up to 9 mm long and with nichtdrüsigen bristles and with short glandular hairs.
The crescent-shaped stamens are about one millimeter long, the ovary occupied bald or only weakly with nichtdrüsigen bristles. The stylus is short, the scar einlappig and semicircular. The round, hairless fruit capsule opens along elongated slots and has a diameter of 3 to 4 millimeters and are numerous, less than 1 mm long, ovate to nearly round seeds freely.
Distribution and location
Genlisea subglabra is native to Burundi, Tanzania, Zambia, Malawi and the Democratic Republic of Congo on iron crust soils and swamps, there associated with Cyperus species and Lobelia mildbraedii.
Systematics and Botanical History
The first description was in 1906 by Stapf basis from 1896 collected in Zambia material. As a diagnostic feature serve the dense nichtdrüsige pubescence of the calyx as well as the dense glandular pubescence of the ovary. Like all African species belongs within the genus Genlisea subglabra in the section Genlisea.
Peter Taylor classified along in its floristic treatments of the African water hose plants of the 1970s as a subspecies of Genlisea hispidula, this view is no longer being followed today.
