Hab. Oahu, Sandwich Islands; on the Kaala Mountains, in the 

 district of Waianae. (Also found by Lay & Collie, Gaudichaud, &c.) 

 Maui ; on the mountains in the western part of that island. 



An herbaceous vine (the root unknown), with much the habit of 

 S. angulatus. Stems slender, strongly angled, nearly glabrous or gla- 

 brate, sometimes at first beset with slender and glandular-tipped 

 hairs. Leaves thin and membranaceous, 3 to 5 inches in diameter, 

 rounded and cordate-angled, sometimes inclining to reniform and very 

 obscurely lobed, more commonly angularly five-lobed (or seven-lobed ?) ; 

 the lobes very short and triangular, and the sinuses very broad, the 

 terminal lobe largest; the margin barely denticulate; the upper sur- 

 face glabrous, or sparsely papillose-scabrous ; the lower sometimes 

 hispid-pubescent when young, soon glabrate, or more or less papillose- 

 scabrous. Petioles one or 2 inches long, glabrate or glandular-pubes- 

 cent. Tendrils 2-3-cleft. Flowers of both kinds usually from the 

 same axils; the male flowers small (the buds only a line in diameter), 

 in racemose, rather small, and simple panicles, on peduncles of one to 

 3 inches long, which, with the short pedicels, are glandular-pubescent. 

 Our specimens, however, do not well exhibit the male inflorescence. 

 Perianth, as in the genus, accrescent after expanding, becoming nearly 

 3 lines in diameter, at length rotate, five-cleft to the middle, with 5 

 minute and subulate calyx-teeth at the sinuses; the lobes of the 

 corolla triangular-ovate, sparingly pubescent externally. Anthers 5, 

 or sometimes only 4 or 3, collected in a head at the summit of the 

 slender column formed of the united filaments, distinct but sessile, 

 oblong, two-celled, the cells parallel and margining a narrow (or at 

 first roundish) connective, or else one of them one-celled, sinuous, but 

 only moderately so, and capable of being straightened when soaked. 

 Female flowers numerous in a capitulum, terminating a short peduncle
