[Five feet high, in flower during March at Karagué, with a single unbranched erect stem, and now no 
leaves on its lower part. Тһе three linear portions of the flower are green, spotted with brown, and the 
rest of the flower is yellow. Peduncle twisted. Two stamina.—J. A. G.] 
4. ANSELLIA AFRICANA (Lindl. Bot. Reg. 1846, tab. 30), var. NILOTICA, Baker. Differs 
only from the Guinea plant by the labellum being as long as the segments of the 
perianth, with narrower and longer lateral lobes, and the column longer as compared 
with the typical form in the same proportion. 
Hab. In thick clusters on tall-stemmed trees, Mbwiga, 7° 30' 8. lat., alt. 1200 feet, Oct. 
1860 (App. Speke's Journ. 648), Col. Grant ! 
[Three feet high. Roots strung on like beads on a thread. Found 30th October, 1860, at 7? 30' S. 
lat., 37? 10' E. long., altitude 1200 feet, living in thick masses on the lofty -stemmed trees about the valleys. 
It has so wild an appearance from its spots and its yellow flowers, which are barred inside and outside 
like a zebra’s skin, that I named it the “Giraffe parasite." Тһе Wahiao use its jointed roots medi- 
cinally, and call the plant * mitool’o.”—J. А. G.] 
5. POLYSTACHYA, sp. In fruit only. Habit of the small forms of P. luteola, with 
narrow leaves, and an oblong instead of а eylindrical capsule. 
Hab. With Angræcum Grantii, at Madi, Dec. 1862 (App. Speke's Journ. 648), Col. Grant ! 
[This orchid was observed stuck to an Angrecum which grew in the moss-covered boughs of a Kigelia. 
The bulb is onion-shape, and cuts solid. The seed-vessels, with six outer ribs, ripe in December, are 
clongated, and not so large as а currant. One side is split open, emitting the seeds, which resemble a 
white fibrous dust. This is used by the natives as explained under Angrecum.—J. A. G.]
