Beiatan Conco: Katanga District, Elisabethville, 1440 m. alt., 
Nov. 22nd 1911, Rogers 10148. Same locality, in thick woods near 
water, Sept. 1923, Von Hirschberg 28. ‘‘ Sepals and petals pale green; 
lip snowy white shaded with orange to pale yellow, two mauve lines 
from base to edge.’”’ 
This is apparently not an uncommon plant in the 
fringing forests along the rivers and streams in a wide 
area from eastern Angola to the Abercorn district of 
Northern Rhodesia. As in its nearest ally, V. imperialis 
Kraenzl., the lip and column, which are united nearly 
to the top of the latter, form a trumpet-shaped tube 
which is very narrow at the base and widens gradually 
upwards. The sides of the lip are folded over the apex 
of the column, but the lip is not distinctly lobed though 
there may be a sinus of varying depth in the centre of 
the apex. The scales forming the central crest are very 
variable in character, the front ones being long and nar- 
row, entire or more or less toothed, and resembling those 
forming the crest of V’. imperialis. The central ones, 
however, are broad and transversely placed, usually long- 
pectinate or incised all around, but showing some ap- 
proach to the simpler scales in V. africana Lindl., V. 
ramosa Rolfe and similar species. Farther back the scales 
are shorter but still pectinate or with long irregular 
teeth, while in the lower part the outgrowths consist 
entirely of short papillae-like hairs. The specific epithet 
is given in allusion to this assemblage of scale-like out- 
growths.
