New Malay Orchids. 
BY HIN. RIDLEY: 
The following new orchids mostly from the peninsula have 
been obtained since the publication of the Orchids of the Malay 
Peninsula in the Journal of the Linnean Society Vol. XXXII, 
. 2138. 
: In working up the group for the Flora of the Malay Pen- 
insula I find we have as at present known 530 species belonging 
to 87 genera, and doubtless there are many more to be dis- 
covered especially in the northern districts, and on the hills of the 
east of the Peninsula. I have added a few descriptions of new 
species also from Sumatra, the orchid flora of which is really 
very little known, though the more showy kinds have been 
exported thence for many years.
