This species is evidently closely allied to Burmannia lutescens, Becc., and B. tridentata, 
Becc. It differs, however, from the former in the shape of the flower, which is obovate, and 
in the anthers, which are broader than long; from the latter by the presence of distinct 
though very small inner perianth-lobes and the exceedingly short spur of the anthers. 
BURMANNIA LONGIFOLIA, Beccari, Mal. i. 244, t. xiii. f. 1-5. 
North-west face of Mount Kinabalu at 5000 feet (Low).
