Holothrix longicornu G.J.Lewis, J. S. African Bot. 4: 53 (1938).
Plants erect, scape without bracts, with dense short retrorse hairs, 65-154 mm high; leaves with dense, soft, short, sinous hairs. Flowers'. Sepals connate at base, glabrous, 1.5-2.5 x c. 0.5 mm. Lip camose, divided into 3-5 short, broadly linear lobes, 2.5-3 x 1-1.5 mm; spur narrowly conical, straight, longer than lip, 3-4 mm long.
Once collected near Port Elizabeth (Eastern Cape), and habitat and flowering time are unknown.
Only the type specimen has been seen but as there are a number of plants in the type gathering and they consistently show these characters the species can be regarded as separate. This species is closely related to Holothrix cernua and Holothrix brevipetala as shown by the retrorse, hispid hairs on the scape.
