The foliage of this plant resembles closely that of Rigiolepis 
borneensis, Hook. fil., being thickly coriaceous, with nerves and 
reticulations sunk above and raised beneath, but the racemes 
are elongate, the bracts small and the corolla large, as in some 
species of Vaccinium notably V. acuminatissimum, Miq. 
V: monanthum, Ridley, sp. nov.; V. unifloro, J. J. 
Sm., affinis, re virgatum, floribus glabris 
Frutec ramis gracilibus virgatis, partibus juvenibus minute 
hirtis. Folia lanceolata, longe acuminata, basi rotundata vel 
in basin breviter angustata, 4-5.5 cm. longa, 1-1.5 em. lata, 
coriacea; nervi intramarginales tenues sed conspicul, fere a

This species is allied to V. uniflorum, J. J. Smith in Ic. Bogor. 
t. 320. It differs in the shape of the foliage, and the completely 
glabrous flowers. V. wniflorum is a slender epiphyte but 
V. monanthum is a longer branched, twiggy plant, apparently 
not epiphytic. 
ese two species with their peculiar reduction of inflorescence 
to a single very small flower emitted from an axillary tuft of 
narrow perulae are so utterly unlike any other species of the 
genus Vaccinium, that it may eventually be necessary to propose 
a new genus for their reception.
