ORCHID STUDIES, II 
BY 
Lovis O. WILLIAMS 
THE FOLLOWING SPECIES of Dendrobium have been 
found in a collection of about two hundred specimens 
awaiting determination. These species were collected in 
the Philippine Islands. 
The subgenera outlined by Kriinzlin in his monograph 
of Dendrobium are used here in preference to the more 
complicated system proposed by Schlechter in his ‘‘Die 
Orchideen von Deutsch-Neu-Guinea.’’ The latter sys- 
tem was followed by Ames in his first comprehensive 
account of the Philippine Orchidaceae (Orchidaceae 5 
(1915) 106-113). One of the species described below, 
which would belong to the genus Desmotrichum if Kriinz- 
lin’s treatment were followed, is referred to Dendrobium.
