The common lime is widely distributed in the Philippines in 
cultivation and is variable in its fruit characters. The common 
Tagalog name for this is dayap, but the illustrative material, 
representing a form with fruits 4 to 6 cm in diameter, has the 
Ilocano name gorong-gorong. 
Illustrative specimens from Umingan, Pangasinan Province, 
Luzon, May, 1914 (Merrill: Species Blancoanae No. 44); Anti- 
polo, Rizal Province, Luzon, January, 1914, there known as 
dayap (Merrill: Species Blancoanae Nos. 45, 436). 
Citrus reticulata Blanco Fl. Filip. (1837) 610 (sp. nov.) ; ed. 2 (1845) 425; 
ed. 3, 2 (1879) 408=CITRUS NOBILIS Lour. 
_ This is the most popular and most abundant orange in the 
Manila market, the supply coming chiefly from Batangas Prov- 
ince. It is universally known in the Philippines as naranjitas, 
a name applied to no other form. The fruits, when mature, 
are usually 5 to 6 cm in diameter, greenish to yellow, with a 
very loose skin.

Citrus papillaris Blanco FI. Filip. (1837) 610 (pappilaris) (sp. nov.); ed. 
2 (1845) 425; ed. 3, 2 (1879) 409=CITRUS NOBILIS Lour., var. 
Blanco’s entire description consists of the following: “Tronco 
con espinas. Hojas dos veces aserradas, con alas en el peciolo. 
Baya grande, con un gran pezon en la base, y de aqui toma el 
nombre. Como los Sintoris. T., Pis-ong. Espec. nueva.” By 
reference to the native name sintoris Blanco compares it to 
his Citrus reticulata—Citrus nobilis Lour. It is probably a var- 
iety of Loureiro’s species, or perhaps a hybrid between it and
