The flowers of Agfostophyllum Mearnsii, especially the constricted 
labellum, recall those of A. javanicum Bl., but the foliage is quite distinct- 
ive. I have seen material from Sumatra (Schlechter 15967) named A. 
javanicum Bl. by Dr. R. Schlechter which resembles A. Meamsii, but 
which has longer, narrower leaves.

Agrostophyllum pelorioides is easily distinguishable from all other Phil- 
ippine species, of which we have any record, by the labellum and broad pe- 
tals. The labellum is similar to the petals in form and size and is scarcely 
saccate.
