[Lindley merely places in the genus Bulbophyllum the Diphyes 
odorata, Blume (Bijdr. 312), adding nothing to the meagre 
description of Blume. The plant, which from the description 
I conclude to be Blume’s Diphyes odorata, occurs in the Malay

This species has’a long slender raceme of innumerable 
flowers, orange-coloured in the bud and when first open, and
