EXCLUDED SPECIES. 
Paspalum elegans Fliigge; 1<’.-Vill. Nov. App. (188.3) 310, an American 
species, Villar’s identifieation undoubtedly being erroneous.

“Habitat in Imzonia” I’resl. Probably erroneously localized and a native of 
tropical America, not the Philippines. From the description it appears to be a 
synonym of Paspalum aiireum H. B. K., an American species.

“Hab. ad Soisogon” Presl. Although credited to Luzon by Presl, this may be 
an American species. It is possibly referable to Digitaria. 
(26) DIGITARIA Scop. 
Spikes usnaJly digitately arranged at the summit of the culms. Spike- 
lets narrow, acute or acuminate, in twos or threes on one side of a flat, 
winged, or triangular rhachis; glumes three or four, the three outer ones 
memliranous, the first often minute or wanting. 
Species about 25, widely distributed in tropical and temperate regions, by 
some authors referred to Pasjutlum, by others to Panicum-; five species in the 
Philippines. 
1. Splkelets about 3 mm. long. 
2. Spikes many, 10 to 20, scattered or whorled along a 
somewhat elongated axis - - (2) D. 
2. Spikes few, 2 to 6, digitate or approximate at the apex of

1. Spikelets about 1.5 mm. long. 
2. Spikes digitate or approximate at the ends of the culms.
