Endemic? 
This species has the habit of Panicum sarmenlosum Roxb., but differs from 
tliat and from Panicum montanum Roxb., in the long first glume which equals 
the spikelet in length. Mez identified No. 654 Merrill as Panicum montanum, 
but the specimen does not agree with the descriptions of that s])ecies. I have 
based the above identification entirely on the short description of Panicum, luxu- 
rians given by Kunth in his Enumeratio. but the description does not apply in 
all particulars. Panicum cordalum Biise, from Java appears to be the sam(>
