IXTliODUCTIOX, 



In the prcrii'iit paper an atteiiipt has been made to summarize our 

 present knowledge of Philippine Graminea', 72 genera and 226 species 

 and varieties being recognized, all, with the exception of a few species 

 indicated in the text, Inised on specimens actually examined by the 

 author and deposited in the herl)arium of the Bureau of Science. The 

 material on which this article is l)ased has been received within the 

 past four and one-half years, and collected within that time, with the 

 excejition of 53 specimens of Cuuiing's Philipi)ine collection (1836-1840) 

 received from the British Museum. Jn addition to the above 2'liS 

 species and varieties admitted, .">(; others are considered in my attempt 

 to account for all the species that have l)eeii credited to the Philippines 

 by various authors. These are enumerated under doubtful and excluded 

 species following the genera or tribes to which they belong, and for the 

 most part have been credited to the Philippines through errors in locali- 

 zation or identification hy Cavanilles, Lagasca, Presl, and F.-Villar. 



The descriptions of Philippine grasses are widely scattered in botan- 

 ical literature, but from the fact that the present list will undoubtedly 

 be considerably augmented in tlie near future, it has not been thought 

 advisable to include descriptions of the s})ecies in the present paper, 

 although short descriptions of the tribes and genera, and keys to the
