It is common and widespread in forest and thicket, throughout the summer rainfall areas of East and Southern Africa. DescriptionIt produces a distinctively flattened caudex, often with lobes that spread out. The creeping shoots grow throughout most of the year, though each will periodically die back and be replaced from the central caudex root stock. In dryer conditions it can become deciduous. The green creeping foliage can reach 4 meters or more in height. It is an extremely widespread and variable species, with several extremely distinct varieties.[1] Threats and conservationIt is threatened from illegal collecting for traditional medicine, as well as for the horticultural trade. As a consequence it is listed as Vulnerable.[2] References1. ^Plant encyclopedia article 2. ^Dioscorea sylvatica - Redlist article External links{{Commons category}}{{wikispecies}}{{Taxonbar|from=Q15604548}}{{Monocot-stub}} 1 : Dioscorea |
