78 SPECIES BLANCOANAE 
the leaves of Bambusa lima as “angusta” is an error, due to 
Steudel’s and Munro’s translation of the word “anchas”’ as nar- 
row; it signifies wide, for he definitely states that the leaves 
are “lanceoladas, anchas’’, that is, lanceolate, broad. Blanco’s 
description, so far as it goes, applies entirely to the species as 
here interpreted and to no other Philippine bamboo known to me. 
Illustrative specimen from Mount Maquiling, Laguna Province, 
Luzon, July, 1912, comm. E. Quisumbing, here known as anos 
(Merrill: Species Blancoanae No. 41). 
Bambus diffusa Blanco FI. Filip. (1837) 269 (sp. nov.); ed. 2 (1845) 187; 
ed. 8, 1 (1877) 334=SCHIZOSTACHYUM DIFFUSUM (Blanco) 
Merr. in Am. Journ. Bot. 3 (1916) 62 (Schizostachyum acutiflorum 
Munro, Dinochloa diffusa Merr.). 
In spite of Blanco’s description of the leaves as ‘“‘pelosas 
por debajo,” there is very little doubt that this is the species 
he intended, as frequently the leaves are slightly hairy. It is 
possible that he may have included more than one species in his 
description. The habit, most of the uses, the fruits, and its 
habitat, as indicated by Blanco, all apply to Schizostachyum 
acutifiorum Munro, which is common and widely distributed in 
Luzon, especially in those provinces near Manila. Blanco’s spe- 
cific name is the older, and I believe that it should be retained 
for the material distributed as illustrating the species, while 
certainly typical Schizostachyum acutiflorum Munro is also 
typical Bambusa diffusa Blanco —Schizostachyum diffusum Merr. 
Illustrative specimen from Los Bafios, Laguna Province, Lu- 
zon, March, 1914, comm. F. C. Gates (Merrill: Species Blanco- 
anae No. 418). 
CYPERACEAE 
CYPERUS Linnaeus 
Cyperus subrotundus Llanos Frag. Pl. Filip. (1851) 14 (sp. nov.); F.-Vill. 
& Naves in Blanco Fl. Filip. ed. 3, 4? (1880) 8=CYPERUS DIFFOR-. 
MIS Linn. 
Llanos’s description agrees perfectly with this very common 
and widely distributed Linnean species. It is a characteristic 
weed of the rice paddies and low wet fallow lands. 
Illustrative specimen from Manila, Luzon, November, 1914 
(Merrill: Species Blancoanae No. 162). 
Cyperus imbricatus Llanos Frag. Pl. Filip. (1851) 17 (sp. nov.); F.-Vill. 
& Naves in Blanco FI. Filip. ed. 3, 4" (1880) 11, non Retz., nec ad seve: = 
CYPERUS RADIATUS Vahl. 
This species was reduced by Naves to Cyperus neler 
Presl=Mariscus stuppeus (Forst.) Merr. (M. albescens Gau- 
dich.), to which species Llanos’s description does not well apply,
