NEW OR NOTEWORTHY PHILIPPINE PLANTS, VII. 249 



Pattioum nodosum Kuntli. which is closely allied, differs mainly in being much 

 smaller, with shorter, narrower leaves, and much smaller panicles. The type of 

 Knnth's species was from the Philippines, P. nodosum being based on /'. multinodc 

 Presl, non Lam. Balansa. apparently assuming the Indian form to be typical 

 Panicum nodosum Kunth, has distinguished the smaller form, apparently typical 

 P. nodosum Kunth, as P. ouonbiensc. 



I am disposed to refer to Panicum malabaricum (Linn.) Merr., two specimens 

 from the Philippines, Palmas Island, Merrill 5367, and For. Bur. 5349 Merritt, 

 from Mindoro. The former was previously referred by me to /'. nodosum Kunth. 



In a broad sense Panicum malabaricum might include P. nodosum Kunth, but 

 I am disposed to consider the small form described by Kunth as worthy of specific 

 rank.

This species was previously determined by me as Panicum luxurious Wilhl., 

 but is apparently not that species. I have examined the material in the Will- 

 denow Herbarium so named, there being two specimens, one marked "Klein Ind. 

 1799" which is apparently a form of Panicum prostration Lam.=7'. reptans Linn., 

 the other from St. Vincent, collected by Bory, which may be the same as P. 

 cacspitosum Sw. Willdeiiow, Enum. 1 (1833) 109, gives as the only locality for 

 the species 'Luzonia," an apparent error on his part. 



The specimens cited above closely resemble Panicum montanum Roxb.. but can 

 be readily distinguished from that species by the first glume being as long as the 

 spikelet. The Philippine material differs from Javan cordatum in its relatively 

 narrower and less prominently cordate leaves, but does not seem to be specifically 

 distinct from that species.

The oldest name for this common and widely distributed species is Panicum 

 reptans Linn., as shown by A. S. Hitchcock 1. c, who has examined the type in 

 the Linnean herbarium.

Mr. A. S. Hitchcock has examined the type of Lamarck's Panicum proliferum 

 in the Paris Herbarium, and finds it to be identical with Panicum miliars Lam., 3 

 and has accepted P. dichotomiflorum Michx. as the earliest valid name for the 

 species, commonly identified by American authors as /'. prostratum Lam. 1 am 

 now of the opinion that the species of tropical Asia and Malaya is distinct from 

 the American form, and have here adopted Roxburgh's specific name for the 

 oriental form, as it seems to be the earliest valid one.
