258 SPECIES BLANCOANAE 
MELOCHIA Linnaeus 
4 Hypericum pentandrum Blanco FI. Filip. (1837) 614 (sp. nov.) ; ed. 2 (1845) 
430; ed. 3, 2 (1879) 417=MELOCHIA UMBELLATA (Houtt.) Stapf. 
Melochia arborea Blanco op. cit. 524 (sp. nov.); 365; 311, ¢. 1839 =MELO- 
CHIA UMBELLATA (Houtt.) Stapf. 
This species is common and widely distributed in the Philip- 
pines at low and medium altitudes, being one of the charac- 
teristic shrubs and small trees that quickly appear in recently 
cleared land that has been allowed to revert from cultivation. 
There is no doubt whatever but that both Hypericum pentandrum 
Blanco and Melochia arborea Blanco are the same species. The 
synonymy of the species is complicated, and I have previously 
made an attempt to clear it up; see Philip. Journ. Sci. 9 (1914)

Illustrative specimen from Los Bajios, Laguna Province, Luzon, 
June, 1914, comm. E. aceite: (Merrill: Species Blancoanae 
No. 40). 
Melochia supina Linn.; Blanco Fl. Filip. (1887) 524; ed. 2 (1845) 365; ed. 
8, 2 (1879) 810=MELOCHIA CONCATENATA Linn. (M. corchori- 
folia Linn.). 
Geruma subtriloba Blanco Fl. Filip. (1837) 182 (sp. nov.); ed. 2 (1845) 
130; ed. 3, 1 (1877) 2832=MELOCHIA CONCATENATA Linn. (M. 
corchorifolia Linn.). 
Melochia supina Linn. was correctly interpreted by Rinne, 
but it is a synonym of M. concatenata Linn., which has page 
priority over both M. corchorifolia Linn. and M. supina Linn. 
The same form was otherwise described by Blanco as a new 
species, Geruma subtriloba Blanco, which was correctly reduced 
by Fernandez-Villar. It is very common and widely distributed 
in the settled areas of the Philippines at low and medium 
altitudes. 
Illustrative specimen from Manila, Luzon (Merrill: Species 
Blancoanae No. 325). 
WALTHERIA Linnaeus . 
WALTHERIA AMERICANA Linn.; Blanco Fl. Filip. (1887) 523; ed. 2 — 
(1845) 364; ed. 3, 2 (1879) 309. : 
The Linnean species was correctly interpreted by Blanco. 
Waltheria indica Linn, is a synonym and is the name used by 
most authors for the species; however, Waltheria americana — 
Linn. has priority and should be retained. The species is com- — 
mon and widely distributed in the Philippines, occurring as a 
weed in the open country of the settled areas at low and medium eb, 
altitudes. 
Illustrative specimen from Maragondong, Cavite Province, 
Luzon, October, 1914 (Merrill: Species Blancoanae No. 156).
