9? SPECIES BLANCOANAE 
I previously considered it to be a form of Colocasia antiquorum 
Schott=C. esculentum Schott. From the native names cited, 
there being no other data from which its status can be deter- 
mined, as Blanco gives no description, it can scarcely be other 
than a form of Alocasia macrorrhiza Schott. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
November, 1914, there known as biga (Merrill: Species Blan- 
coanae No. 630). 
COLOCASIA Schott 
Calla gaby Blanco Fl. Filip. (1837) 659 (sp. nov.) Caladium esculentum 
Vent.; Blanco op. cit. ed. 2 (1845) 459; ed. 3, 3 (1879) 64=COLOCASIA 
ESCULENTA (L.) Schott. (C. antiquorum Schoit.). 
The taro, widely known in the Philippines as gabi, is exten- 
sively cultivated, a number of forms or varieties being found 
in the Archipelago. It is at times at least subspontaneous, but 
is certainly not a native of the Philippines, 
Illustrative specimen from Los Bajios, Laguna Province, Luzon, 
May, 1914, comm. F. C. Gates and F. Q. Otanes (Merrill: Spe- 
cies Blancoanae No. 21). 
TYPHONIUM Schott 
Arum divaricatum Blanco Fl. Filip. (1837) 657; ed. 2 (1845) 458; ed. 3, 
3 (1879) 62, non Linn. (vel Linn. p. p. tantum) =TYPHONIUM 
CUSPIDATUM (Blume) Decne. 
This was reduced by Naves to Typhonium divaricatum (Linn.) 
Decne., but the original Arum divaricatum Linn. was in part 
Typhonium divaricatum Decne. and in part T. cuspidatum 
Decne.; the Philippine form described by Blanco is apparently 
the latter. It is found only in and near towns in the Philip- 
pines and probably is an introduced plant in the Archipelago. 
Illustrative specimens from Manila, Luzon, August, 1912, Sep- 
tember, 1916 (Merrill: Species Blancoanae Nos. 676, 970). 
ARISAEMA Linnaeus 
Calla polyphylla Blanco Fl. Filip. (1837) 659 (sp. nov.) =Caladium ? 
digitatum Blanco op. cit. ed. 2 (1845) 459 (nom. nov.) ; ed. 8, 3 (1879) _ 
64=ARISAEMA POLYPHYLLUM (Blanco) Merr. (A. cumingit 
Schott.). 
A species of wide distribution in the Philippines at medium — 
and higher altitudes, exceedingly variable in vegetative char- 
acters. The leaves vary greatly in width, and the maximum — 
length I have observed, on very luxuriant specimens, is about 
25 cm,
