Holothrix incurva

Holothrix incurva, previously H. rupicola, is a slender ground orchid growing from tuberous roots.

The plants produce tiny flowers in unbranched spikes during spring and summer. The lower petal or lip is spurred at the back and divided into thread-like, narrow lobes at its tip. 

The species distribution is in or near Lesotho, in the far east of the Free State, the far west of KwaZulu-Natal and the far north of the Eastern Cape.

The habitat is summer rainfall, cold winter grassland of the Drakensberg. The habitat population is deemed of least concern early in the twenty first century.

The leaves of Holothrix species are often few in number, small and short-stalked, or prostrate. Plants of this genus are rarely cultivated, probably due to the insignificant size of the flowers (Wikipedia; www.plantzafrica.com; http://redlist.sanbi.org).
