A typical member of sect. Pentaceras, differing from 
the other species in the way in which the various charac- 
ters are combined. The specific epithet is given because 
of the resemblance of the flowers to a number of tiny men 
bowed in prayer. The description is drawn up from dried 
and spirit material of both gatherings. 
Habenaria tenuifolia Swmmerhayes nom. nov. 
Habenaria hymenophylla Schlechter in Engler Bot. 
Jahrb. 58 (1915) 498, non Schlechter (1911). 
In view of the earlier use of the epithet hymenophylla 
for an Australian species, [ propose the above new name 
for the African plant described by Schlechter. I have 
now seen material of this species from southern ‘Tangan- 
yika Territory, the Katanga district of the Belgian Congo, 
Northern Rhodesia and eastern Angola. 
Habenaria njamnjamica Araenzlin in Engler Bot. 
Jahrb. 16 (1898) 106. 
Hatbenaria foliolosa Kraenzlin |.c. 51 (1914) 872. 
On examination of the type gatherings of these two 
species I can find no significant differences. The species 
has been collected in the Sudan, Kenya Colony, Belgian 
Congo and Northern Rhodesia. 
‘The members of the group of species within sect. Pen- 
taceras, to which this species belongs, resemble strongly 
certain species in sect. Ceratopetalae, particularly H. 
stenorhynchus Schlechter. From these they may be dis- 
tinguished by the thin, not horn-like, front lobe of the 
petals and the gradually clavate, not capitate, stigmas, 
as well as by other less obvious features.
