 nearly glabrous, herbaeeous, dioieious vine, the ultimate branchlets 2 mm in diam. or less, 

 sulcate, pale-brownish. Leaves chartaeeous, shining on both surfaces, brownish-olivaeeous, 

 oblong-ovate, entire, 9 to II cm long, 4,5 to 6 cm wide, the apex slenderly and sharply 

 acuminate, the base cordate, the sinus rather broad the basal lobes rounded, the basal 

 margins usually with 1 or 2 prominent glands; lateral nerves including the basal pair 

 4 to 6 on each side of the midrib, prominent, arched-anastomosing, the primary reti- 

 culations lax, distinet; petioles about 2 cm long, distinet, glandulär in the upper part, 

 the glands sessile, up to I mm in diam.; tendrils slender, up to 6 cm long. Staminate 

 flowers axillary, solitary or in pairs, the pedicels up to 3,5 cm long, the subtending 

 bracts inclosing the buds broadly ovate when spread, acute or obtuse, the base promi- 

 nently cordate, up to 3,5 cm long, scabrid on both surfaces. Calyx-tube broad, nearly 

 flat, 10 to 12 mm in diam., the lobes oblong-ovate, sharply acuminate, scaberulous, 

 about 1,5 cm long, 8,5 mm wide. Corolla lobes ovate, the larger ones up to 5,5 cm

 in the lower part. Stamens 3, 6 to 8 mm long, one entire, two 2-lobed, the con- 

 nectives more or less papillose, each stamen or lobe with a conspieuous, ascending, 

 lateral, papillate-villous, lanceolate appendage, about 4 mm long, from a broad base." 



"British North Borneo, Batu Lima, near Sandakan (Ramos n. 1303, Oct. 1920). 

 In forests at low altitudes. The petals are described as white, the central portion 

 nearly black. The species is allied to Momordica denticulata Miq., from which it is 

 distinguished by its thinner, smaller, entire leaves, its glandulär petioles, its acuminate 

 sepals, and its larger flowers. A very similar species is represented by Native Col- 

 lector 2812 (Bur. Sei.), Moulton 64, from Selungo, Upper Baram, Sarawak, collected 

 on Nov. 22, 1914, but which differs in its truncately rounded, not cordate leaves, and 

 apparently smaller flowers and bracts. The speeimens are imperfecta
