68 SPECIES BLANCOANAE 
SETARIA Beauvois 
Setaria pilifera Llanos Frag. Pl. Filip. (1851) 34; F.-Vill. & Naves in 
Blanco FI. Filip. ed. 3, 4* (1880) 25, non Desv., nec Spreng.=SETA- 
RIA FLAVA (Nees) Kunth. 
This species was reduced by Fernandez-Villar to Panicum helo- 
pus Trin.=Panicum setigerum Retz., fide Hooker f., a species 
that does not extend to the Philippines and to which Llanos’s 
description does not apply. The description does not entirely 
apply to Setaria flava Kunth, but I know of no other Philippine 
grass that at all agrees with Llanos’s description. The species 
is common and widely distributed in the Philippines.

1915 (Merrill: Species Blancoanae No. 766). 
Panicum miliaceum Blanco Fl. Filip. (1837) 39; ed. 2 (1845) 28; ed. 3, 1 
(1877) 52, non Linn.=SETARIA ITALICA (Linn.) Beauv. 
This species, known in the Philippines as dava or dawa, is © 
probably of prehistoric introduction. It is fairly common in — 
cultivation, but is usually grown on a very small scale. 
Illustrative specimen from Batangas Province, Luzon, August, 
1914 (Merrill: Species Blancoanae No. 484). 
CENCHRUS Linnaeus 
Cenchrus hexafilorus Blanco Fl. Filip. (1837) 36 (sp. nov.); ed. 2 (1845) 
24; ed. 3, 1 (1877) 46=CENCHRUS ECHINATUS Linn. 
This species was reduced by Fernandez-Villar to Pennisetum © 
nigricans (Presl) Mig.—Pennisetum compressum R. Br., while — 
in my previous consideration of Blanco’s species I considered it — 
as certainly the same as Pennisetum macrostachyum Trin., chiefly — 
on account of the known distribution of the two species of Pen-— 
nisetum in the Philippines. However, Blanco’s description does — 
not at all apply to Pennisetum, but manifestly does apply to — 
Cenchrus echinatus Linn., a species of wide distribution and — 
abundant in and about towns in the Philippines. The state- 
ment “Los involucros son membranaceos, y muy tiesos, y doblan- 
dose algunos hacia dentro, forman una cosa algo semejante a — 
los abrojes” (abrojes=caltrop) leaves absolutely no doubt as — 
to the species intended, yet it is difficult to conceive just why 
Blanco described the involucres as membranaceous and at the © 
same time as very hard or solid. The species was certainly — 
introduced into the Philippines from Mexico. 3
