[Kunth’s Chinese locality is taken from Roxburgh ; but Roxburgh’s Panicum filiforme is obviously a true 
Panicum, allied to his P. lineare {P. pseudodurva, N. ab E.) and P. commutatum, N. ab E., but differing 
by the upper glume being only half the length of the neuter floret, and both three-nerved and slightly villous 
on the margin.]
