reference of this to Passiflora serrulata Jacq., in the second 
edition of the Flora de Filipinas. A series of specimens from 
cultivated plants, collected in various parts of the Philippines, 
agree perfectly with Blanco’s description, and also agree with 
material from tropical America determined as Passiflora edulis 
Sims. Pending a thorough revision of the genus, it seems best 
to refer the form Blanco described to Sims’s species. It is 
only occasionally found in cultivation and is nowhere abundant 
in the Philippines.

zon, from cultivated specimens, October, 1916 (Merrill: Species 
Blancoanae No. 987). 
CARICACEAE 
CARICA Linnaeus 
CARICA PAPAYA Linn.; Blanco Fl. Filip. (1837) 803; ed. 2 (1845) 553; 
ed. 3, 3 (1879) 212. 
Carica hermaphrodita Blanco op. cit. 805 (sp. nov.); 554; 212=CARICA 
PAPAYA Linn. 
The Linnean species was correctly piiwited by Blanco, the 
normal form with dioecious flowers. The form described by 
Blanco as Carica hermaphrodita bears small fruits from female 
or perfect flowers on the elongated staminate inflorescences, 
such plants otherwise resembling normal staminate ones. This 
form is rare, individual trees being occasionally found. The 
papaya was introduced into the Philippines at an early date by 
the Spaniards, is now common and widely distributed in the 
Archipelago, and in some localities is thoroughly naturalized.

BEGONIACEAE 
BEGONIA Linnaeus 
Begonia capensis | Blanco Fl. Filip. (1837) 724; ed. 2 (1845) 501; ed. 3, 
3 (1879) 127, ¢. 413, non Linn. f.=BEGONIA NIGRITARUM Stend. 
This species is widely distributed in the Philippines and pre- 
sents considerable variation. Fernandez-Villar was correct in 
reducing Blanco’s Begonia capensis to Begonia rhombicarpa A. 
DC. (1859), but Steudel’s name (1821), based on Acetosa nigri- 
tarum Kamel, is the older. This species is still commonly known 
to the Tagalogs as lingat and pifgol bate. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 494).
