Curiously enough Kassner 3127, which is cited on page 
119 of Kraenzlin’s monograph as the basis of his new spe- 
cies, P. Schinziana, is also cited on page 82 under P. 
Doggettii Rendle & Rolfe. Like P. galeata (Sw.) Reichb. 
f., the present species is placed correctly in sect. Cultri- 
formes, being closely allied to its West African congener. 
It differs in the smaller flowers, the shorter mentum and 
the differently shaped lip, the claw being short and broad, 
the lateral lobes rounded and not clearly separated from 
the middle lobe, while the middle lobe itself has a promi- 
nent recurved acute apex. The lip, as remarked by 
Kraenzlin, is very difficult to flatten out, assuming dif- 
ferent outlines according to the way it is flattened.

On examination it appears that the type specimens of 
the above possess no differences of specific importance, 
the main differences being those of size, both vegetatively 
and florally. The type of P. inconspicua seems to be a 
very small specimen bearing exceptionally large flowers. 
Mr. W. J. Eggeling, however, has collected many speci- 
mens in Uganda showing all intermediates between 
Bagshawe 425 and the Gold Coast material as regards 
vegetative characters; these specimens also help partially 
to bridge the differences in flower size. The species evi-
