Dendrochilum Weberi is the first representative of § Eudendrochilum 
which has been reported from the Philippine Islands. In general habit 
it resembles Z>. aurantiacum Bl. very closely, but in the details of the flower 
it is quite distinct. According to notes made by Mr. Weber the flowers 
are cream-colored. In dried specimens they are brownish. By the addition 
of D. Weberi to the genus every section of Dendrochilum is now represented 
in the Philippines, the sections Acoridium and Platyclinis by numerous 
species, § Pseudacoridium by D. Woodianum and § Eudendrochilum by P. 
Weberi,

The labellum is quite distinctive, the auricles being strongly curved and 
in conjunction with the terminal portion resembling a ram's head. In dried

plant bears two or three leaves.
