species that does net extend to the Philippines; I previously 
thought that it might be the same as Manisuris exaltata O. Ktze. 
=fottboellia exaltata Linn. f.; see Govt. Lab. Publ. (Philip.) 27 
(1905) 91. Blanco’s description, however, although very im- 
perfect, applies to Panicum stagninum Retz. Retzius’s species 
is the only Philippine grass known to me to which Aegilops 
fluviatilis Blanco can be referred. It is common in low wet 
places, in stagnant pools, etc., about Manila. Orthopogon lolia- 
ceus as described by Llanos is certainly the same as Retzius’s 
species, 
I}lustrative specimen from Manila, Luzon, October, 1913 
(Merrill: Species Blancoanae No. 352). 
Orthopogon dichotomus Llanos Frag. Pl. Filip. (1851) 38 (sp. nov.) ; F.-VilL 
& Naves in Blanco Fl. Filip. ed. 3, 4* (1880) 28=PANICUM COLO- 
NUM Linn. 
This species was reduced by Fernandez-Villar to Panicum 
stagninum Retz., but Llanos otherwise described P. stagninum 
in the same publication as Orthopogon loliaceus; moreover his 
description of Orthopogon dichotomus certainly does not apply to 
Panicum stagninum Retz., but agrees closely with P. colonum 
Linn. It is very common and widely distributed in the Philip- 
pines, growing in the open country of the settled areas from 
sea level to an altitude of at least 1,600 meters. 
Illustrative specimen from Manila, Luzon, December, 1914 
(Merrill: Species Blancoanae No. 710). 
Orthopogon hispidus Spreng.; Llanos Frag. Pl. Filip. (1851) 37; F.-Vill. & 
Naves in Blanco Fl. Filip. ed. 3, 4* (1880) 27=PANICUM CRUS 
GALLI Linn. 
Orthopogon subverticillatus Llanos op. cit. 88 (sp. nov.); 283=PANICUM 
CRUS GALLI Linn. 
Orthopogon hispidus, as interpreted by Llanos, was reduced by 
Fernandez-Villar to Panicum hispidulum Lam., which is a syno- 
hym of Panicum crus galli Linn., and O. subverticillatus was 
reduced by the same author to Panicum colonum Linn. The re- 
duction of the first species is certainly correct, although Llanos | 
may not have had exactly the form described by Sprengel. The 
reduction of Orthopogon subverticillatus Llanos to Panicum 
colonum is impossible, the plant being described as being a yard 
and a half high. Orthopogon subverticillatus Llanos is certainly 
the form of Panicum crus galli Linn. with the spikes, or some 
of them, arranged in whorls of three’s, as in the illustrative 
material distributed herewith. The species is common and 
widely distributed in the settled areas of the Philippines, grow- 
ing as a weed in rice lands and along slow streams.
