322 DIAGNOSES SPECIERUM NOVARUM. 
This species comes from the same locality and from approxi- 
mately the same altitude as Dendrochilum grandiflorum, Pfitz. 
It differs in the larger flowers which have a labellum of quite a 
different shape from that of the species named. The general 
outline of the labellum approximates to that of Dendrochilum 
longifolium, Reichb. f., except that the apex is rounded and not 
pointed; cf. fig. in Engl. Pflanzenr..—Kranz. Coelogyninae, 
p. 101. Among the species monographed in the above work by 
Kranzlin it seems to belong to the section Délaiata, Pfitz., in the 
neighbourhood of Dendrochilum latifolium, Lindl., and in 
company with D. grandiflorum, Pfitz. 
The colour is said by the native collector to be white; in 
the dried state it is yellowish in tinge. This orchid is dedicated 
to the Ranee of Sarawak.
