Holothrix incurva is a slender ground orchid producing its 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.
H. incurva occurs in the Drakensberg region in summer rainfall grassland, as well as in Lesotho.
The leaves of Holothrix species are often few in number, small and short-stemmed or even prostrate. Plants of this genus are rarely cultivated, due to the insignificant size of the flowers (www.plantzafrica.com).
