COMPOSITAE 379 
SPHAERANTHUS Linnaeus 
Sphaeranthus alatus Blanco Fl. Filip. (1837) 635 (sp. nov.) =Sphaeranthus 
indicus Blanco op. cit. ed. 2 (1845) 442 (Sphaerantus) ; ed. 3, 3 (1879) 
29, non Linn. =SPHAERANTHUS AFRICANUS Linn. 
Fernandez-Villar considered that Blanco correctly interpreted 
Sphaeranthus indicus Linn., but this species has never been found 
in the Philippines. The plant Blanco described is undoubtedly 
S. africanus Linn., which is a common weed in and about towns 
in the settled areas of the Archipelago. 
Illustrative specimen from Obando, Bulacan Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 396). 
PTEROCAULON Elliott 
Sphaeranthus elongatus Blanco Fl. Filip. (18387) 636 (sp. nov.); ed. 2 
(1845) 443; ed. 3, 3 (1879) 30=PTEROCAULON REDOLENS (Forst.) 
F.-Vill. (P. cylindrostachyum Clarke). 
A weed, occasional in and about towns, in fallow lands, etc., 
certainly introduced in the Philippines. 
Illustrative specimen from Bataan Province, Luzon, July, 
1913 (Merrill: Species Blancoanae No. 341). 
GNAPHALIUM Linnaeus 
Xeranthemum staehelina Blanco Fl. Filip. (1837) 629, non Linn.=Gna- 
phalium dichotomum Blanco op. cit. ed. 2 (1845) 439; ed. 3, 3 (1879) 
20, non Willd. =GNAPHALIUM LUTEO-ALBUM Linn. 
This species is widely distributed in the mountains of north- 
ern Luzon; Blanco’s material was from Agoo, Union Province, 
Luzon. While the specimens undoubtedly represent the spe- 
cies Blanco described, I am not sure that they are Gnaphalium 
luteo-album Linn. Radlkofer has suggested to me that the 
Philippine Gnaphalium luteo-album, so named, may be a Heli- 
chrysium. : 4 
Illustrative specimen from Baguio, Benguet Subprovince, 
Luzon, May, 1914 (Merrill: Species Blancoanae No. 17). 
ECLIPTA Linnaeus 
Anthemis cotula Blanco FI. Filip. (1837) 633, non Linn.=Artemisia viridis 
Blanco op. cit. ed. 2 (1845) 436 (sp. nov.) ; ed. 3, 3 (1879) 14, t. 284, 
non Linn.=ECLIPTA ALBA (Linn.) Hassk. 
This species is very common and widely distributed in the 
settled areas of the Philippines, but certainly is an introduced 
plant in the Archipelago. : : |
