66 SPECIES BLANCOANAE 
Illustrative specimen from the bank of an estero (stagnant 
stream), Manila, Luzon, January, 1915 (Merrill: Species Blan- 
coanae No, 684). 
Panicum radicans Llanos Frag. Pl. Filip. (1851) 43; F.-Vill) & Naves in 
Blanco Fl. Filip. ed. 3, 4* (1880) 31, non Retz.= PANICUM DISTA- 
CHYUM Linn. 
This was reduced by Fernandez-Villar to Panicum prostratum 
Lam.=P. reptans Linn., but Llanos’s description does not apply 
to that species. The description is very indefinite, but mani- 
festly applies to some species in the group having racemosely 
arranged spikes and the spikelets on one side of the rachis. The 
description does not fit Panicwm distachyuwm Linn. in all details, 
but better applies to this species than to any other known to 
me. Common and widely distributed throughout the Philippines 
at low and medium altitudes. 
Illustrative specimen from Manila, Luzon, December, 1914 
(Merrill: Species Blancoanae No. 711). 
Panicum crispum Llanos Frag. Pl. Filip. (1851) 42 (sp. nov.); F.-Vill. & 
Naves in Blanco Fl. Filip. ed. 3, 4* (1880) 30—=PANICUM PSILO- 
PODIUM Trin. 
Fernandez-Villar reduced this to Panicum prostratum Lam., 
a species that does not at all conform with Llanos’s description. 
The only Philippine representative of the genus known to me 
that conforms at all with the description and with the indicated 
habitat is Panicum psilopodium Trin., at least as that species 
is represented by currently identified Philippine material. 
Panicum violaceum Llanos Frag. Pl. Filip. (1851) 42 (sp. noy.); F.-Vill 
in Blanco Fl. Filip..ed. 8, 4* (1880) 31—=PANICUM NODOSUM 
Kunth (P. multinode Presl). 
There is very little doubt as to the correctness of this reduc- 
tion of Llanos’s species, although his description is rather vague 
and decidedly imperfect; the reduction is in agreement with 
that of F.-Villar. It is common and widely distributed at low 
and medium altitudes in the Philippines, being especially abun- 
dant in abandoned clearings, borders of thickets, etc. 
Illustrative specimen from Antipolo, Rizal Province, ee 
August, 1915 (Merrill: Species Blancoanae No. 944). 
Panicum polygonatum Llanos Frag. Pl. Filip. (1851) 41; Fl. Filip. ed. 3, 
4* (1880) 30 (poligonatum), non Kunth, nec Schrad.=PANICUM 
AUPEEIGKULE Rudge. : 
Llanos’s description applies unmistakably to Rudge’s species 
and to no other known Philipping erAaR. It is widely distributed
