 neath beset tvith large glands. Fruit oblong, obtuse at both ends, 

 smooth, not grooved nor ribbed, only 2 inches long, with a thin and 

 yellowish rind when dry, sparing fibrose-reticulated within. Seeds 

 oval, compressed, but tumid, brown, with a nearly smooth surface; 

 the edge very slightly margined.

Hab. Mangsi Islands, in the Sooloo Sea. 



Apparently an extensively climbing vine; with an angled stem, 

 smooth and glabrous, or nearly so, as is the whole plant. Leaves 

 ample, 7 to 9 inches in diameter, thin and membranaceous, three- 

 ribbed from the base, the lateral ribs forked, subrotund, cordate with a 

 deep and narrow sinus, angularly five-lobed; the lobes broadly trian- 

 gular, lh to 2, or the terminal one 3 inches long, acuminate, nearly 

 entire, barely repand, or the basal lobes usually with a few coarse 

 teeth posteriorly. Tendrils five-cleft, or four-cleft. Male peduncle 

 axillary, longer than the petiole, strongly angled, bearing a many- 

 flowered raceme; the flowers subtended, and as it were involucrated, 

 with large, obovate, glandless, more or less toothed, foliaceous bracts, of 

 half an inch or an inch in length, but shorter than the slender pedicels 

 of the developed flowers, which are from an inch to an inch and a 

 half in length. Tube of the (male) calyx clavate-turbinate, half an 

 inch long; its 5 segments linear-lanceolate, almost an inch in length, 

 remotely pinnatifid-laciniate, nearly the length of the apparently white, 

 broadly cuneate petals. These are retuse, with a central apiculation, 

 the broad summit on each side laciniated into a copious, long, and
