Dioscorea strydomiana is a critically endangered species of yam from South Africa with fewer than 250 mature individuals known to exist.
Dioscorea strydomiana is shrub-like, grows up to 1m (03feet) tall with an above ground tuber that is large and rough-textured,. It has herbaceous stems from the upper part of the tuber each year, and then die back over the course of the dry season. Its ovate or elliptical leaves are found on short stalks and arranged alternately along the stems.[1]
It is dioecious and has very small flowers that are less than in diameter with six cream-coloured or white tepals which appear in late spring to early summer. The fruits resemble dry capsules that split at the ends to release seeds.
It is a recently discovered species, an extremely slow growing plant, but it has great horticultural potential.
The specific epithet honors the late Gerhard Strydom, a conservationist with the Mpumalanga Tourism and Parks Agency, who noticed the plant for sale at a market and tracked it down to its habitat.
D. strydomianas range is only limited to the Oshoek area in Mpumalanga, South Africa, near the border with Eswatini where it is found at 1100m-1150mm (3,600feet-3,770feetm) above sea level.
The plant is used in traditional medicine (like other Dioscorea species).
