I looker f., reduces tliis to Panicum maximum Jacq., hut I'resl's description 

 does not closely apply to the latter species. I have seen no specimens of Panicum 

 maximum from the Philippines, and if il docs occur in the Archipelago, it will 

 be only as an introduced plant.)

Endemic? 



This species has the habit of Panicum sarmentosum Roxb.. but differs from 

 that and from Panicum montanum Roxb., in the long first glume which equals 

 the spikelet in length. Mez identified No. 554 Merrill as Panicum montanum, 

 but the specimen does not agree with the descriptions of that species. I have 

 based the above identification entirely on the short description of Panicum luxu- 

 rians given by Kuntli in his Enumeratio, but the description does not apply in 

 all particulars. Panicum cor datum Buse, from Java appears to be the same
