218 MR. HENRY RIDLEY ON ORCHIDEZ AND 
Rhaphidophora and Epipremnum. They seldom confuse other 
epiphytic plants with orchids; and distinguish them from 
epiphytic ferns, &c., with considerable accuracy. The terrestrial 
orchids with large plicate leaves, such as Calanthe and Spatho- 
glottis, are usually called “ Lwmbah,” or the reduplicative 
“ Tulumbah” for “ Lumbah-Lumbah.” Properly speaking, this 
name belongs to Curculigo swmatrana, Roxb., and the similarity 
of the leaves is the cause of the transference of the name.

This species belongs to the group with broad petals, and a 
three-lobed lip (the median lobe nearly bifid). It is allied to 
O. insectifera, Hook.f. The flowers appear to have been yellow.
