Very local on tree trunks. It is a pretty species with sweetly- 
scented flowers. The peduncle and pedicels elongate in fruiting, 
and the large capsule splits up into its separate ribs when 
dehiscing. I should have taken this plant for D. breviflorum, 
Lindl., in Journ, Linn. Soc. (Bot.) iii. (1859) p. 14; but Sir 
J. D. Hooker refers this to D. bicameratum, Lindl. Lindley’s 
description is rather incomplete.
