Disa purpurascens is a species of orchid found in South Africa (SW. Cape Prov.).

About 10 narrow, rigid leaves, about half as tall as the plant, grow from a basal rosette.

The base of the plant is often surrounded by a sheath of old leaf fibers.

Each flower has a blue hood and side wings, with a dark purple lip below.

[2] While the flowers look similar to those of Disa graminifolia, they differ in having an upcurved lip margin and a conical spur.
