CUCURBITACE^, «gg 



Var. y. foliis pedatilobis, nempe fere tripartitis, segmentis lateralibus 

 plus minus bilobis. 



Hab. Hawaii, Sandwich Islands ; in the upper part of the forests 

 of Mouna Kea. 



The three specimens (none of them very perfect), apparently from 

 different stations, but in the same belt of mountain forest, differ in 

 their foliage. In that assumed as the typical form, the leaves are 

 broadly cordate, with a deep and narrow sinus, occasionally almost 

 reniform, mostly acuminate, undivided, and showing scarcely any 

 tendency to beeome lobed, 31 to 6| inches in diameter, glabrous, as 

 are the angled stems and even the inflorescence, membranaceous, bat 

 not very thin; the margin sharply denticulate with mucroniform 

 callous-pointed teeth. The var. f3. presents a triangular-cordate leaf, 

 5 inches long and 3 wide at the base, where it somewhat inclines to 

 have lateral lobes, the apex long-acuminate: the petiole somewhat 

 pubescent. The var. y. exhibits smaller leaves, pedately lolyed, being 

 all three-parted, with narrow sinuses, the lateral divisions more or less 

 two-lobed. The male inflorescence, in the best developed specimens, 

 consists of 3 compound and lax racemose panicles, on an axillary 

 short peduncle (of an inch or two in length) : pedicels filiform, 2 or 3 

 lines long, glabrous. Perianth of the male flowers glabrous, five-cleft 

 to the middle, with minute calyx-teeth at the sinuses externally, 

 when expanded nearly rotate and 3 lines in diameter. Anthers 5 or 6, 

 somewhat twisted, nearly as in S. pachycarpus. Perianth of the 

 fertile flowers not seen. Female inflorescence at the summit of a 

 peduncle from the same axil with the male panicle, and sometimes 2 

 inches long. The fructified ovaries about 3 together, oblong, pointed 

 with a tapering beak, glabrous, one-celled, with a single suspended 

 ovule. Fruit oblong, nearly an inch in length, 4 or 5 lines in dia- 

 meter, apparently somewhat fleshy and drupaceous when fresh, 5-6- 

 angled, but less sharply so than in the preceding species, smooth and 

 glabrous, the thick pericarp in the dry state coriaceo-crustaceous, one- 

 celled, one-seeded, not beaked. Seed with a smooth and rather thin 

 testa : cotyledons oblong, thickish.
