work. Our plant differs from 2. crenulatum in its stouter 
habit, its larger flowers and in the entire in place of 
denticulate angles of the ovary. The plant is grown in 
a basket suspended from the roof of a tropical house at 
Kew, and thrives well under the treatment suitable for 
other tropical species of the genus. It flowered at Kew 
in May, 1917, when the figure now published was pre- 
pared.
