120 SPECIES BLANCOANAE 
but the identification of it is certain, as the form distributed 
herewith is the only representative of the genus known from 
the Philippines. Fernandez-Villar reduced it to Salix tetra- 
sperma Roxb., and it is certainly very closely allied to that species - 
if not identical with it; it seems to differ from Roxburgh’s 
species in its long-petioled leaves. It is known in the Philippines 
only from Luzon, where it is of very local occurrence ‘in 
Rizal and Laguna Provinces; I have sterile specimens of what 
is apparently the same species from Cagayan Province. Blanco’s 
specimens were from Bulacan Province, Luzon.

Luzon, November, 1914 (Merrill: Species Blancoanae No. 116): 
JUGLANDACEAE 
ENGLEHARDTIA Leschenault 
Gyrocarpus pendulus Blanco Fl. Filip. ed. 2 (1845) 55 (sp. nov. as Giro- 
carpus pendulos); ed. 3, 1 (1877) 104, t. 387=ENGLEHARDTIA 
SPICATA Blume (E. philippinensis C. DC.). 
The identity of Blanco’s species is very certain, and there 
seems to be no doubt as to the correctness of the reduction to 
Englehardtia spicata Blume. The Philippine form has been 
described by C. de Candolle as a distinct species, Hnglehardtia 
philippinensis, but Blanco’s specific name is older than this one, 
should a critical revision of the genus show the Philippine form 
really to be different from that described by Blume. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
November, 1914 (Merrill: Species Blancoanae No. 176). 
FAGACEAE 
CASTANOPSIS Spach 
Fagus philippensis Blanco Fl. Filip. ed. 2 (1845) 503 (sp. nov.); ed. 3, 3 
(1879) 182=CASTANOPSIS PHILIPPENSIS (Blanco) Vid. 
This species was erroneously reduced by Fernandez-Villar to 
the very different Castanopsis sumatrana A. DC. It is widely 
distributed in Luzon, but is apparently nowhere abundant. 
Illustrative specimen (topotype) from Angat, Bulacan Prov- 
ince, Luzon, December, 1914 (Merrill: Species Blancoanae No. 
672). 
QUERCUS Linnaeus 
Quercus glabra Blanco Fl. Filip. (1837) 727, non Thunb.=QUERCUS 
OVALIS Blanco op. cit. ed. 2 (1845) 502 (sp. nov.); ed. 3, 3 (1879) 
129, t. 440 (as Q. conocarpa, non Oudem.). 
This is apparently a valid species and is known from only 
a few localities in central Luzon. Quercus blancoi A: DC.
