FLORA OF EASTERN TROPICAL AFRICA. 889 
transversely oblong lip is 18} lines broad and 131 long from the 
mouth of the spur to the tip of the short recurving apiculus in 
the centre of the broadly emarginate front; the posterior 
portion bears a longitudinal raised flat lamella } inch long and 
1; line broad in the middle, from which it tapers to a sharp point 
back and front. The gracefully recurving spur is 2 inches long 
by line in thickness. The short thick column is 2 lines long by 
2; thick, the broad and rounded lobes of the rostellum 1 line long. 
The pollinia are whitish, with a short caudicle } line long and a 
rather large gland (4 line across). The roundish, rather flat 
anther is 14 line long by 1? broad. 
An interesting species, falling between Angraecum eburneum, 
Thou. (Bourbon), and 4. superbum, Thou. (Madagascar) ; from 
the former it is at once distinguished by its larger, broadly oblong, 
emarginate lip, in which it resembles superbum ; it differs from the 
latter in having a smaller flower with shorter and proportionately 
broader sepals and petals and clavate leaves.

The only leaf present is 2} inches long by 11 lines in its 
broader upper part, with 17 longitudinal nerves. The longest 
raceme is 13 inches and bears 13 bracts; the few lower inter- 
nodes are thick but rapidly become slender above the third fiom 
the base ; the blunt sub-hooded bracts are j inch long. The open 
flowers measure 1? inch across ; the ovate-lanceolate dorsal sepal 
is 3 inch long by 4 lines broad, the narrower but otherwise 
similar lateral pair 10 by 3 lines. The broadly oblanceolate 
petals are 3 inch by 3} lines, and have 5 conspicuous nerves with 
two feebler marginal ones. The broad lip (7 lines long by 6 lines 
broad) has a crisped margin, especially towards the front, and 9
