Strumaria bidentata is a rare plant, an autumn flowering geophyte. The plant is one of 24 species in a less known genus of the Amaryllidaceae family. Strumaria flowers drop off when withered, unlike those of Hessea species, another genus of the family with similar flowers.
Distribution of Strumaria bidentata is limited to a small and remote area, in the Richtersveld and on the Namibian side of the Gariep River, near the river bank and close to its mouth. What grows in the Namib Desert surely qualifies as a true desert flower. The plant grows in sandy desert soil among plentiful loose pebbles.
Two rounded or tongue-shaped leaves with red margins stand erect from the ground in winter after the autumn flower has disappeared (Williamson, 2010; iSpot; www.rareplants.co.uk).
