Hab. Terminal moraine of sheet-glaciation, 10,400 ft., Mt. 
Kenya, July 3, 1893: J. W. Gregory. 
A robust plant 14-16 inches high, the thick soft reddish stem 
almost completely hidden by the sheathing leaves and bracts. 
The basal leaves are lanceolate and subpatent from a sheathing 
membranous base, more or less acute, folded at the midrib with 
about eight darker dorsally conspicuous veins on each side, 
5-6 inches long by about Linch broad. The stem-b:acts are 
ovately lanceolate acute, or almost acuminate and closely ad- 
pressed, and torm a transition from the basal leaves to the 
narrower oval-lanceolate, lanceolate, or almost oblanceolate acu- 
minate bracts, 12-14 lines long and 2}—4 lines broad, slightly 
exceeding the flowers in length. The broad, somewhat oblique 
lateral sepals are a little over 4 lives long and half as broad, and 
5-nerved ; the dorsal hood is 33 lines high, and posteriorly pro- 
duced at the base into a Jong gracefully curving cylindrical spur 
slightly pointed at the tip, 10 lines long by § line wide. It 
shelters the erect narrow slightly falcate lateral petals, which are 
3-nerved, obliquely inserted at the base, and 3} lines long by } line 
broad. The obtuse lip is 34 lines long by 4 line wide in the upper, 
broader portion. The rounded anther-cells are { line long. 
Approaches Disa Welwitschii, Reichb. f., from Angola; but is 
a larger, coarser plant, more resembling the southern D. Coopers, 
Reichb. f., in habit. The flowers are about the same size as in 
D. Welwitschii; but are at once distinguished by the larger spur, 
the broader labellum, and narrower lateral petals.
