1. Trichosanthes cucumerina, Linn. Sp. PI. Ed. 1, 1008. Stems 

 slender, angled, puberulous. Leaves membranous, orbicular- reniform to 

 broadly ovate in general outline ; the edges remotely denticulate, often 

 more or less deeply 3-5 or 7-lobed ; the lobes broad with acute but not 

 acuminate apices and often sinuate margins, the base deeply cordate, 

 the sinus often sub-rectangular ; upper surface sparsely pubescent or 

 sub-glabrous, the lower deciduously pubescent at first, ultimately sub- 

 scabrid ; length 2-4 in. and breadth about the same ; petiole 1-2 in., 

 pubescent ; tendrils slender, sulcate, puberulous, 2-3-fid. Male peduncles 

 rather longer than the leaves, pubescent, bearing a few flowers towards 

 the apex, ebracteate. Flowers *5-l in. in diam. at the mouth ; the 

 tube 2 or 3 times longer, cylindric, a solitary male flower sometimes 

 from the same axil as the peduncle. Female flower on a peduncle '5 in. 

 long, fruit 1-3 in. long, narrowly ovoid, the apex conical, red when ripe ; 

 seeds half ellipsoid, compressed, corrugated. Lour. Flor. Cochchin,

The Perak plant has larger flowers than any Indian specimen, and I refer it to 

 T. cucumerina with some hesitation.
