Very slender, up to 46 cm. high; the lower 1 — 2 leaves sheath-like, cauline 
5 — 8, gradually passing off into the bracts, linear, acute or acuminate, in dried 
specimens setaceously apiculate, inconspicuously nerved, with the sheath up 
to 15 cm. long, usually 9 — 12 cm. long, 0-4 — 1 cm., very rarely up to 1-5 cm., 
broad; raceme laxly 10 — 22-fl., rarely up to 30-fl., flowers ascending, among 
the very small ones in the genus, green, the flowering-axis almost straight; 
bracts foliaceous, long and setaceously acuminate, 1-8 — 0-5 cm. long; pedicels 
finally up to 1-2 cm. long; lateral sepals reflexed, broadly half-moon-shaped, 
slightly narrowed towards the apex, obtuse, up to 0-5 cm. long; odd sepal 
erect galeate, scarcely up to 0-4 cm. long; petals entire ovate-oblong, some- 
what falcate (the anterior margin convex, posterior concave), as long as the 
odd sepal; lip furnished at the base (at the mouth of the spur) with an erect 
process, 3-partite, lobes subfiliform, the lateral 0-5 cm. long or a little more, 
the intermediate almost 0-7 cm. long, spur at first curved, then hanging 
straight down, up to 2-2 cm. long; rostellum, when flattened out, broadly 
elliptical in outline, with a linear-oblong process on the middle of the face, 
the middle lobe erect linear elongate, longer than the erect gland-bearing side- 
lobes; anther, viewed laterally, subquadrate; pollinia obliquely globose; stig- 
matic arms ascending; ovary about 0-8 cm. long. 
The drawing was made from living specimens collected by Mr A. G. 
McLoughlin near Pretoria.
