GRAMINEAE 71 
LEERSIA Swartz 
LEERSIA HEXANDRA Sw.; Llanos Frag. Pl. Filip. (1851) 26; F.-Vill. & 
_ Naves in Blanco Fl. Filip. ed. 3, 4+ (1880) 18. 
This species was correctly interpreted by Llanos. It is widely 
distributed in the Philippines, growing in open muddy places 
and in shallow water. In and about Manila it is extensively cul- 
tivated for green forage and is the chief source of forage supply 
for the City of Manila. The land is prepared in the form of 
paddies, as for the cultivation of rice. There are many hundred 
hectares of land in and near Manila devoted to the cultivation 
of this grass. It is universally known as barit or zacdte.

SPOROBOLUS R. Brown 
Spermachiton involutum Llanos Frag. Pl. Filip. (1851) 25 (gen. et sp. 
nov.); F.-Vill. & Naves in Blanco Fl. Filip. ed. 3, 47 (1880) 2 Af gh 
SPOROBOLUS INDICUS (L.) R. Br. 
This genus and species was reduced by Fernandez-Villar to 
Eriochloa punctata Ham.—E. ramosa O. Ktze., a species to which 
Llanos’s description does not apply, and which Llanos cer- 
tainly describes, op. cit. 24; 16, as Miliwm zonatum. While the 
description is very imperfect and indefinite, I consider that the 
statements “semilla vestido con un saquito,” in the generic de- 
scription, and “semilla * * * cubierta con un saquito,” in 
the species description, very definitely refer the plant to Sporo- 
bolus. The description in all essentials applies to Sporobolus 
indicus, a species that is common and widely distributed in the 
settled areas of the Philippines.

CYNODON Persoon 
Chloris rufescens Llanos Frag. Pl. Filip. (1851) 31; F.-Vill. & Naves in 
Blanco Fl. Filip. ed. 3. 4* (1880) 21, non ? Lag. =CYNODON DAC- 
TYLON (Linn.) Pers. 
This was reduced by Fernandez-Villar, with dbuibt: to Cynodon 
dactylon, but the reduction is unmistakably correct. Llanos does 
not indicate whether or not he considered his Chloris rufescens 
as a new species, and adds no literature reference. The de- 
scription applies perfectly to the very common Cynodon dactylon 
which is commonly known in the Philippines as grama, a name
