178. CERATOSTYLIS BI. 
Ceratostylis philippinensis Rolfe ex Ames Orch, 1: 79, with fig. 
Among the orchids collected on Mount Mariveles by Elmer D. Merrill and 
sent alive in 1905 to North Easton was this interesting species which has grown 
luxuriantly in my collection, forming dense tuffs of semiterete leaves from the 
axils of which the sweet-scented, snow-white flowers emerge in August and 
September. The margin of the lip is slightly revolute near the middle and on 
the disk beyond the middle are two inconspicuous papillose calli. 
This species has also been collected recently by R. C. McGregor, Bur. Sci. 8447, 
near Pauai, Benguet Subprovince, Luzon, at an altitude of 2,100 m. 
218. PHAIUS Lour. 
Phaius flavus Lindl. Gen. Sp. Orch. Pl. 128. 
The material which I refer here may be conspecific with P. philippinensis N. 
FE. Brown, a species which I have not seen. There are several details, however, 
in Mr. Brown’s description which do not agree with my specimens. The entire 
lip of my plant suggests P. philippinensis, also the thin keels on the disk. On 
the other hand P. flavus is a very variable species and P. philippinensis may be 
one of its variants. Mr. Brown’s description refers to the fugaceous floral bracts. 
In my material the bracts are persistent.
