156 SPECIES BLANCOANAE 
central Luzon southward, but not as yet reported from the shores 
of northern Luzon. Hernandia sonora Linn. was based on both 
oriental and occidental references, but the species is ‘typified by 
the American plant, so that Blanco was in part correct in refer- 
ring the Philippine form to H. sonora Linn. dH. peltata Meissn. 
is very closely allied to the older H. ovigera Linn., and may have 
to be reduced to the Linnean species.

ILLIGERA Blume 
Gronovia ternata Blanco FI. Filip. (1837) 186 (sp. nov.) ; ed. 2 (1845) 132; 
ed. 3, 1 (1877) 2836=ILLIGERA LUZONENSIS (Presl) Merr. 
Halesia ternata Blanco op. cit. 399 (sp. nov.); 279; 2: 153=ILLIGERA 
LUZONENSIS (Presl) Merr. 
The species is widely distributed in Luzon and has several 
synonyms. Its oldest specific name, however, is supplied by 
Henschelia luzonensis Pres] Rel. Haenk 2 (1831) 81, t. 63, the 
type of which I have seen in the Prague herbarium. Presl’s 
description is faulty, and his figures of the floral details are 
erroneous in some particulars. For this reason Mr. Dunn took 
up Blanco’s specific name in preference to Presl’s; see Journ. 
Linn. Soc. Bot. 38 (1908) 294. The other synonyms are Iiligera 
ternata Dunn, I. dubia F.-Vill. non Span., IJ. meyeniana Kunth, 
and J. appendiculata Vid., non Blume. There is no doubt in my 
mind that Gronovia ternata Blanco and Halesia ternata Blanco 
represent the same species. Both are described in the same 
work, the former from flowering specimens, the latter from 
fruiting specimens. a

ARGEMONE Linnaeus 
ARGEMONE MEXICANA Linn.; Blanco Fl. Filip. (1837) 454; ed. 2 (1845) 
316; ed. 8, 2 (1878) 220, t. 187. 
The Linnean species was correctly interpreted by Blanco. It 
was introduced from Mexico by the Spaniards at an early date 
in colonial history either as an ornamental plant or for its medic- 
inal properties. It is now widely distributed in the Philippines, 
growing especially about buildings and in vacant lots in towns, 
in waste places, etc.
