 Monostachya Merrill gen. nov. in Philippine Journ. of Sei. V (1910). p. 330. 



This proposed genus is readily recognizable by its solitary, erect 

 spikelet, a character most unusual in Gramineae- It was originally 

 placed by me near the genus Festuca, differing in a number of characters. 

 The floral structure of Monostachya is near Festuca and Bromus- In 

 habit it closel}'^ approximates that of Centrolepis phiUppinensis Merr.
