Buso River, above the mouth of Tosapik Creek, Morobe District, el- 
evation 5000-6000 ft., flowers wine red, March 14, 1941, Clemens 
12018 (Tyrer in Herb. Ames). 
Bulbophyllum schizopetalum belongs in the subgenus 
Hapalochilus, section Trachychilus of Schlechter’s treat- 
ment in Die Orchideen von Deutsch Neu-Guinea (Fedde 
Repert. 1 (1912) 698 et seq.). The species is apparently 
closely allied to B. xanthophaeum Schitr., but differs in 
the narrower sepals, in the more deeply lobed petals, in 
the smaller lip (which also differs in its muriculations and 
in not being suleate below) and in the larger leaves.
