DENDROBIUM CRUMENATUM 
Dendrobium — tree-living, from its epiphytic habit, 
crumen at um — purse-sh aped. 
English name: Pigeon Orchid. 
Country oj origin : Burma to Malaysia and S. 
China. 
Colour : White, with some yellow on 
the lip. 
Garden use : A wild plant, very common as 
an epiphyte on trees and bushes 
in gardens, on rubber and fruit 
trees, and in similar situations. 
Well known because of the 
simultaneous flowering ol all 
plants in one locality nine days 
after a sudden drop in tempera- 
ture caused by rainstorms. This 
starts the development of 
flower buds which have already 
grown to a certain size and 
await the stimulus given by the 
temperature drop. The frag- 
rant flowers last only one day. 
Propagation : By division. 
A, base of stem showing the pseudobulb, part of 
a leafy stem and the inflorescence. 
B, vertical section of flower. 
C, seed pod.
