LUFFA Linnaeus 
? Momordica operculata Blanco Fl. Filip. (1837) 770; ed. 2 (1845) 530; ed. 
8, 3 (1879) 173, t. 334 (as Luffa petola Sering., the cultivated form) 
non Linn. =LUFFA CYLINDRICA (Linn.) Roem. 
This species is common and widely distributed in the Philip- 
pines at low and medium altitudes in the settled areas, both 
wild and cultivated. The wild form is the one described by 
Blanco, and this has somewhat smaller leaves and smaller fruits 
than the cultivated form. 
Illustrative specimens (wild form) from Pasay, Rizal Prov- 
ince, Luzon, October, 1914 and Angat, Bulacan Province, Luzon, 
December, 1914 (Merrill: Species Blancoanae Nos. 222, 660). 
Cucumis acutangulus Linn.; Blanco FI. Filip. (1837) 776; ed. 2 (1845) 
534; ed. 3, 3 (1879) 179, t. 288 =LUFFA ACUTANGULA (Linn.) Roxb. 
This species occurs in the Philippines only in cultivation 
and, unlike the commoner Luffa cylindrica, has not become 
established. In aspect, as to vegetative and floral characters, 
it greatly resembles Luffa cylindrica, but the male flowers have 
three instead of five stamens. The fruits of the two species 
are very different, those of L. cylindrica being cylindric and 
nearly smooth, those of L. acutangula having 10, longitudinal, 
prominent ridges, making the fruit distinctly 10-angled. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
November, 1914 (Merrill: Species Blancoanae No. 107). 
CUCUMIS Linnaeus 
CUCUMIS MELO Linn.; Blanco Fl. Filip. (1837) 775; ed. 2 (1845) 584; ed. 
3, 3 (1879) 179. 
Blanco certainly described the form of this species that is 
placed by Cogniaux under Cucumis melo var. agrestis Naud. 
Fernandez-Villar reduced Cucumis melo Blanco to C. trigonus— 
Roxb., a species that does not occur in the Philippines and one 
to which Blanco’s description does not apply. The species oc- 
curs in the Philippines in the settled areas as an occasional __ 
plant in waste places and in fallow lands, undoubtedly an in- 
troduced naturalized form. Several forms are also cultivated. 
Illustrative specimen from Umingan, Pangasinan Province, 
Luzon, April, 1914, there known as it-timon (Merrill: Species 
Blancoanae No. 728). 
BENINCASA Savi ' 7 eee 
Cucurbita pepo-aspera Blanco Fl. Filip. (1837) 773 (sp. nov.) ; ed. 2 (1845) 
532; ed. 3, 3 (1879) 176, t. 327=BENINCASA HISPIDA (Thunb.) — 
Cogn. (B. cerifera Savi). ‘sae 
The reduction of Blanco’s species to Benincasa cerifera Savi 
was made by Fernandez-Villar, which is manifestly the correct
