3. Dendrocalamus parviflorus Hack, in Philip. Journ. Sci. 3 (1908) Bot. 168. 
Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens, March, 1907. Leyte, 
Palo, Elmer 7 283, January, 1906. Cebu, Cogon, Barrow, June, 1904. 
This seems to be a good species. The Leyte plant has apparently been described 
as Gigcmtochloa Merrilliana Elmer, but I find no difference between it and the 
specimens of Dendrocalamus parviflorus Hack. Barrow gives the vernacular name 
cauayan. 
5. CEPHALOSTACHYUM Munro.

I have been rather puzzled about the genus of this beautiful species, but I 
believe I am correct in considering it to be a Cephalostachyum, very similar to the 
Burmese C. pergracile Munro, and G. flavescens Kurz. The only important dif- 
ference is that instead of a terminal slender rachilla with only a very small rudi- 
ment of glumes, this species has two terminal imperfect flowers. It required long 
search among the spilcelets of the specimens available to find one in flower showing 
perfect stamens, and another in nearly ripe fruit. Merritt gives the vernacular 
name bacto.
