AFRICAN ORCHIDS. XII

OwiINnG To the war situation it has not been found 
possible to publish this paper in the Kew Bulletin, in 
which the earlier numbers of this series have appeared. * 
Professor Oakes Ames, however, has kindly allowed me 
to continue the series in the Botanical Museum Leaflets. 
The present paper deals with the genera Habenaria and 
Polystachya, both of which I have been studying mono- 
graphically for some years. It includes several new spe- 
cies from the very fine collection made by my colleague, 
Mr. EK. Milne-Redhead, in Northern Rhodesia and Ang- 
ola. The type specimens of all the new species are in the 
Kew Herbarium. 
Habenaria (§. Chlorinae) Eggelingii Swmmerhayes 
sp. nov.; species H. tenuispicae Rendle valde affinis, sed 
spica crassiore, floribus fere duplo majoribus, sepalis later- 
alibus et petalis angustioribus, calcari antice (in parte 
apicali) magis dilatato distinguitur. 
Herba perennis, erecta; tubera anguste ovoidea, 1-2 
cm. longa, ut radices laxe tomentosa. Caulis erectus, + 
robustus, spica inclusa usque ad 2 m. altus et 1 em. diam- 
etro, fere glaber, e basi usque ad basin spicae + foliatus.
