Pterygodium flanaganii, previously scientifically known as Corycium flanaganii, is a tuberous perennial that annually reaches heights from 20 cm to 30 cm.
The stem-clasping leaves are numerous, overlapping up the stem. The leaves taper and attenuate to acutely pointed tips, in picture mostly damaged. They are borne close to the stem around which they ascend. The leaves (and floral bracts) are covered in conspicuous brown vein lines running parallel and longitudinally up the yellowish green surfaces.
The species distribution is inland in the Eastern Cape, the southwest of the KwaZulu-Natal Drakensberg and the south of Lesotho. This plant was found flowering in the southeast of Lesotho during January.
The habitat is montane grassland at elevations above 2000 m, often near streams. The habitat population is deemed of least concern, being stable early in the twenty first century (iNaturalist; iSpot; http://www.africanorchids.dk; www.pacificbulbsociety.org; http://redlist.sanbi.org).
