Names
POLYSTACHYA gracilenta Kränzl. [family ORCHIDACEAE], in Engl. Jahrb. xix. 251. —Kränzl. in Engl. Pfl. Ost-Afr. C. 155.
Information
Plant 16–20 in. high. Stem very slender, shining, 1-leaved. Leaves linear, longer than the raceme. Scapes slender, with a few sheaths; panicles short and congested, 1 1/2–2 1/2 in. high; branches ancipitous; inflorescence entirely glabrous. Bracts minute, triangular, acute, much longer than the ovary. Dorsal sepal ligulate, obtuse; lateral triangular, obtuse. Petals linear-spathulate, obtuse, about as long as the sepals. Lip much curved, complicate; side lobes semiobovate, roundish, very small; front lobe oblong, short, obtuse; callus rugulose, on upper third of lip to the apex. Chin conical, obtuse, lightly curved.
Distribution
British East Africa Nile Land Ruwenzori, 8200 ft., Stuhlmann, 2334.
Notes
Allied to P. cultrata, Lindl. The author describes the material as deficient, and seems doubtful whether this species is distinct from the preceding one, though the flowers are described as twice as large. I have not seen it. A specimen from Butagu, Ruwenzori, 8000 ft., Scott-Elliot, 8050! is apparently allied to this species.
