380 SPECIES BLANCOANAE 
WEDELIA Jacquin 
Spilanthes acmella Blanco Fl. Filip. (1887) 620 (Spilanthus) ; ed. 2 (1845) 
433 (Spilantes) ; ed. 3, 3 (1879) 10, non Murr.=WEDELIA BIFLORA 
(Linn.) DC. 
Spilanthes peregrina Blanco op. cit. 622 (sp. nov.); 4384; 1O=WEDELIA 
BIFLORA (Linn.) DC. 
Fernandez-Villar considered that Blanco correctly interpreted 
Spilanthes aecmella, but the description under that name applies 
entirely to Wedelia biflora DC. Blanco’s description of Spilan- 
thes peregrina is very short, but I can see no reason for con- 
sidering that it represents a distinct species. The plant is found 
near the sea throughout the Philippines and is widely known 
as hagonoy. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rill: Species Blancoanae No. 528). 
SPILANTHES Linnaeus 
Spilanthes lobata Blanco Fl. Filip. (1837) 622 (sp. nov.) ; ed. 2 (1845) 434; 
ed. 3, 3 (1879) 11=SPILANTHES ACMELLA Murr. 
This species is of local occurrence in the Philippines at low 
altitudes in the settled areas; certainly an introduced weed. 
Illustrative specimen from Los Bafios, Laguna Province, 
Luzon, March, 1914 (Merrill: Species Blancoanae No. 491). 
COREOPSIS Linnaeus 
Coreopsis gracilis Blanco Fl. Filip. ed. 2 (1845) 591 (Cereopsis) (sp. nov.) ;_ 
ed. 8, 3 (1879) 25=? COREOPSIS TINCTORIA Nutt. 
Fernandez-Villar reduced this to Cosmos caudatus HBK., to 
which, however, Blanco’s description does not at all apply. 
Blanco’s specimens were from cultivated plants, which he thought 
were introduced from Mexico. Cosmos caudatus HBK. has pink 
ray-flowers, while Blanco distinctly states that the ray flowers 
of Coreopsis gracilis were yellow with a brown spot. He may 
have had a form of Coreopsis tinctoria Nutt., but his description _ 
of the achenes does not apply to Nuttall’s species. The form 
described by Blanco is apparently no longer to be found in ne. - 
Philippines. 
BIDENS Linnaeus 
Bidens bipinnata Blanco Fi. Filip. (1837) 628; ed. 2 (1845) 485; ed. 8,3 
(1879) 12, non Linn. =BIDENS CHINENSIS Willd. 
This species is widely distributed in the Philippines in the 
settled areas; certainly introduced. Bidens chinensis Willd. 
has very generally been reduced to B. pilosa Linn. as a synonym, 
but is apparently distinct. ae 
Illustrative specimen from Camarines Province, Luzon, De- 
cember, 1914 (Merrill: Species Blancoanae No. 414). z
