INTRODUCTION. 
In the present paper an attempt has been made to summarize our 
present knowledge of Philijipiue Grarninecp, 72 genera and 226 species 
and varieties being recognized, all, with the exception of a few species 
indicated in the text, based on specimens actually examined by the 
author and deposited in the herbarium of the Bureau of Science. The 
material on which this article is based has lieen received within the 
past four and one-half years, and collected within that time, with the 
exception of 53 specimens of Cuming’s Philippine collection (1836-1840) 
received from the British Mmseum. In addition to the above 226 
species and varieties admitted, 56 others are considered in my attempt 
to account for all the species that have been 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 Philipjiines through errors in locali- 
zation or identification by Cavanilles, Lagasca, Presl, and E.-^Tllar. 
The descriptions of Philippine grasses are widely scattered in liotan- 
ical literature, but from the fact that the present list will undoubtedly 
he considerably augmented in the near future, it has not been thought 
advisable to include descrijitions of the species in the present paper, 
although short descriptions of the tribes and genera, and keys to the
