260 SPECIES BLANCOANAE 
PTEROSPERMUM Schreber 
Pterospermum hastatum Blanco Fl. Filip. (1837) 528 (sp. nov.); ed. 2 
(1845) 367; ed. 3, 2 (1879) 317, t. 182=PTEROSPERMUM DIVER- 
SIFOLIUM Blume Bijdr. (1825) 88. 
This species is common and widely distributed in the Philip- 
pines at low and medium altitudes. On young plants and 
saplings the leaves are usually deeply palmately lobed. Gen- 
erally known as bayog by the Tagalogs. 
Illustrative specimen from Batangas Province, Luzon, August, 
1914 (Merrill: Species Blancoanae No, 532). 
PTEROSPERMUM OBLIQUUM Blanco Fl. Filip. (1837) 529 (sp. nov.) = 
Pterospermum semisagittatum Blanco op. cit. ed. 2 (1845) 368; ed. 3, 
2 (1879) 318, t. 456, non Ham. 
Blanco erred in reducing his Pterospermum obliquum to P. 
semisagittatum Ham., as the latter species does not extend to 
the Philippines. Exact synonyms of Pterospermum obliquum 
Blanco are Sczegleewia involucrata Turcz. (1858), and Pteros- 
permum sczegleewia Turcz. (1863). From Blanco’s description, 
“Hojas * * * blancas * * * por debajo,” itis probable 
that he also included the form later described as Pterospermum 
niveum by Vidal, a species, however, quite distinct from Pteros- 
permum obliquum Blanco as here interpreted. 
Illustrative specimen from Rizal Province, Luzon, December, 
1912 (Merrill: Species Blancoanae No. 286). 
HELICTERES Linnaeus 
Dombeya decanthera Blanco Fl. Filip. (1837) 349, non Cav.=Dombeya 
biserrata Blanco op, cit. ed. 2 (1845) 244 (sp. nov.); ed. 3, 2 (1878) 
90, t. 91=HELICTERES HIRSUTA Lour. (H. spicata Colebr.). 
Mimusops talosan Blanco Fl. Filip. (1887) 284 (sp. nov.); ed. 2 (1845) 
198; ed. 3, 2 (1878) 6=HELICTERES HIRSUTA Lour. 
Fernandez-Villar reduced Mimusops talosan Blanco to Helic- 
teres spicata Colebr. var. lanigera Mast., but H. spicata Colebr. 
is the same as H. hirsuta Lour. This is certainly the correct 
disposition of Mimusops talosan Blanco. It is very curious 
that Blanco should have interpreted as a Mimusops a species | 
so entirely unrelated to that genus. Dombeya decanthera Blanco 
is manifestly the same as Mimusops talosan Blanco. The spe- 
cies is common and widely distributed in the Philippines.
