of a line or two in length, or in fruit becoming 3 to 6 lines long. 

 Perianth pubescent; the tube produced beyond the fusiform-ovate 

 ovary into a narrow neck or short beak, the dilated-limb like that of 

 the male flowers but smaller. Stigmas 3, clavate-capitate, subsessile. 

 Ovary one-celled, with a single suspended ovule. Fruit ovate-pyra- 

 midal, several usually ripening in the head, closely sessile on the 

 summit of the short common peduncle, 5 to 7 lines long, when young 

 puberulent, at length glabrate, wholly unarmed and smooth, five-six- 

 angled, the angles salient and sharp, pointed with a slender bealc of 2 

 or 3 lines in length, which usually withers away before maturity : 

 in the dry state the fruit appears nut-like, the pericarp being thick 

 and hard, nearly crustaceous, one-celled, one-seeded. Seed obovate, 

 turgid ; the testa roughened, thick and coriaceous. Embryo amygda- 

 loid: the cotyledons thicker than in S. angulatus. Radicle short, 

 superior.

An herbaceous vine, probably tall-climbing; the strongly angled 

 stems, like the petioles, &c, somewhat pubescent, or glabrate. Leaves
