NEW OR NOTEWORTHY PHILIPPINE PLANTS, VII.

Panicum nodosum Kimth, which is closely allied, differs mainly in being much 
smaller, with shorter, narrower leaves, and much smaller panicles. The type of 
Ivunth’s species was from the Philippines, P. nodosum being based on P. multinode 
Presl, non Lam. Balansa, apparently assuming the Indian form to be typical 
Panicum nodosum Ivunth, has distinguished the smaller form, apparently typical 
P. nodosum Ivunth, as P. ouonbiense. 
I am disposed to refer to Panicum 'malabaricum (Linn.) Merr., two specimens 
from the Philippines, Palmas Island, Merrill 536 7, and For. Bur. 531/9 Merritt, 
from Mindoro. The former was previously referred by me to P. nodosum Ivunth. 
In a broad sense Panicum malabaricum might include P. nodosum Ivunth, but 
I am disposed to consider the small form described by Kunth as worthy of specific 
rank.

This sjjecies was previously determined by me as Panicum luxurious Willd., 
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 prostratum Lam.=P. reptans Linn., 
the other from St. Vincent, collected by Bory, which may be the same as P. 
caespitosum Sw. Will denow, 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 miliare Lain., 3 
and has accepted P. dichotomiflorum Michx. as the earliest valid name for the 
species, commonly identified by American authors as P. prostratum Lam. I 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.
