Hooker f., reduces this to Panicum maximum Jacq., but Presl's description 

 does not closel}' apply to the latter species. I have seen no specimens of Panicum 

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

 be only as an introduced i:)lant.)

Endemic ? 



This species has the habit of Panicum sarmcntosum 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, luaeu- 

 rians given bj^ Kunth in his Enumeratio, but the description does not apply in 

 all particulars. Panicum cordatum Biise, from Java appears to be the same
