IX, C, 1 Merrill: Plants of Guam 53 
R. C. McGregor 502, Cabras Island, October, 1911. 
A species apparently belonging in the same group with Ischaemum 
murinum Forster, but apparently undescribed. Its rather stout, fulvous- 
villous spikes and its very long awns are characteristic.

non Linn. 
I have seen no Guam specimens of this grass, but from Safford’s notes 
there is no doubt but that the plant determined as Andropogon nardus is 
A. citratus DC. It is widely cultivated in the Indo-Malayan region.
