BULBOPHYLLUM Tlioiiurs. 
Bulbophyllum adenopetalum Liiull. Bot. Rog. 1842, Miso. p. 85. 
Epiphyte at 3,550 ft. alt. on Mount lliilcou, Howcvs (Kloilt-ss, lu-iwly wlnlf, 
slightly straw-colored, Nov. 10, 190C, Merrill (No. 5084). 
Thu petals of the specimens collected by Mr. Merrill are rather lanceolate ami 
acute than spathuhite as in Lindley's colored sketcli of the Sinfjapore plants on 
which is based the description of B. adei^opeiaJwn. The Mount Tlalcon specimens 
agree verj' well in habit with Cunnni/^s I'hilippine specimen^ in L'mdh'i/'s Her- 
barium deterjnined as B. adenopetalum by Lindlvy. Unfortunately I Iiave no 
record of the shape of tlie petals of Lindley's specimens aside from a c<>py of his 
drawinj^ of the Singapore plant which he received fnmi Messrs. fjoddifjefi in 1842. 
This drawing shows a ilowor very similar to thai <>f tiie .specimens in (piestion, 
if the petals are excepted. Notwithstanding the discrepancy that exists between 
the petals of JAndley^s drawing and tlic Mount llalcon i)hiiit 1 refer the material 
collected by Mr. Merrill to B. adenopeialnm. 
B. adenopetalum belongs to a section of BulbopJiylhnn which appears to !« 
very well represented in the Philippines, mainly cliaracterized by the absence 
of \\eIl-de\'cloped pseudobulbs. This section is in great need of careful study 
and revision. To it belongs B, ditsy pet alum Rolfc. 
Singajiore and the Philippines.
