220 SPECIES BLANCOANAE 
impossible reduction from Blanco’s description of the leaves 
as “aovadas, alargadas.” The only Philippine species of the ~ 
genus to which Blanco’s description at all applies is the form 
described by me as Antidesma edule. The Tagalog name cala- 
mantao cited by Blanco does not appear on any of our numerous 
specimens of Antidesma, but is applied to the entirely different 
Erythrophloeum densiflorum (Elm.) Merr., of the Leguminosae; 
Blanco’s description, however, is unmistakably that of an An- 
tidesma. Widely distributed at low and medium altitudes in 
the northern Philippines. . 
Illustrative specimens from Mount Arayat, Pampanga Prov- 
ince, Luzon, February, 1915 (Merrill: Species Blancoanae No. 
718); San Mateo, Rizal Province, Luzon, June, 1912 (Merrill: 
Species Blancoanae No. 915). 
CLEISTANTHUS Hooker f. 
Gluta orgyalis Blanco FI. Filip. ed. 2 (1845) 451 (sp. nov.) ; ed. 3, 3 (1879) 
49=CLEISTANTHUS ORGYALIS (Blanco) Merr. 
Fernandez-Villar reduced this to Cleistanthus ferrugineus 
Muell.-Arg., a species that does not extend to the Philippines. 
For a full description of the species see C. B. Robinson in Philip. 
Journ. Sci. 3 (1908) Bot. 189. 
BRIDELIA Willdenow 
Clutia stipularis Linn.; Blanco FI. Filip. (1837) 818 (sp. nov.) ; ed. 2 (1845) 
564; ed. 3, 3 (1879) 229=BRIDELIA STIPULARIS (Linn.) Blume. 
The Linnean species was correctly interpreted by Blanco, but | 
is referable to the genus Bridelia. It is very common and 
widely distributed in the Philippines at low altitudes. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1913 (Merrill: Species Blancoanae No. 551). 
CROTON Linndeus 
Croton glandulosum Blanco Fl. Filip. (1837) 754 (sp. nov.) =Croton muri- 
catum Blanco op. cit. ed. 2 (1845) 518 (nom. nov.); ed. 8, 3 (1879) 
154, t. 383=CROTON TIGLIUM Linn. 
The croton oil plant is commonly cultivated about dwellings 
throughout the Philippines, its chief use being to stupefy fish. — 
Certainly a purposely introduced plant in the Philippines. 
Illustrative specimen from Camarines Province, Luzon, De- 
cember, 1913 (Merrill: Species Blancoanae No. 308). 
CLAOXYLON Jussieu 
Prockia ? albicans Blanco Fl. Filip. (1887) 430 (sp. nov.); ed. 2 (1845) 
299; ed. 3, 2 (1878) 192—CLAOXYLON ALBICANS (Blanco) comb. 
nov. (C. elongatum Merr.).
