as it lengthens, eventually becoming attached to it.

Abundant by streams, and in wet spots in dense jungle on 
Bukit Timah. The leaves, which are very variable in size, are 
much narrower in proportion to their length than in other 
species, often narrowly lanceolate and acute at both ends. The 
two lateral nerves and the keel are prominent. Usually the 
leaves are tufted at the top of the stem; but sometimes the 
stem is leafy throughout. The raceme is often nearly sessile 
when young, but the peduncle continues to grow as the raceme 
lengthens. The flowers are white, but the tips of the sepals 
are commonly tinted with pink.
