642 PHANEROGAMIA. 



corollas lobis integerrimis ; calyois tubo ultra ovarium fusiforme pro- 

 ducto; bacca oblong a. 



Hab. Samoan or Navigators' Islands; common on Tutuila and 

 Upolu. 



Stem slender, glabrous, as is the whole plant, angled, creeping. 

 Leaves deltoid-cordate, sometimes with the broad sinus rounded, some- 

 times approaching to deltoid-hastate, from 2 to 3i inches long, and 2 

 or 3 inches broad at the base, acuminate, membranaceous, nearly 

 smooth, the margins denticulate, towards the base often repand, or 

 obscurely angulate-toothed. Petioles about an inch long. Tendrils 

 simple. Flowers apparently dioecious (at least the two sexes occupy 

 different branches), "white," solitary in the axils of the leaves, on 

 filiform peduncles, of which the fertile are an inch or more, the sterile 

 2 or 3 inches in length. Calyx of the male flowers campanulate, 

 with 5 setaceous teeth at the sinuses of the five-parted, corolla; the 

 divisions of which are oblong, or two of them lanceolate, 2 or 3 lines 

 long, perfectly entire, and glabrous. Stamens 3, shorter than the 

 petals : filaments short, inserted on the tube of the calyx, distinct : 

 anthers two-celled; the cells straight or nearly so, borne on the 

 margin of the dilated, subcuneate-oval, membranaceous connective, 

 the truncate summit of which is slightly and very obtusely apiculate : 

 one of the three stamens has a narrower, barely oblong connective, 

 but is otherwise similar. A short, obscurely three-lobed gland takes 

 the place of the style. Calyx of the female flowers 6 or 7 lines long, 

 including the ovary (which is 3 or 4 lines long) ; the tube produced 

 beyond the fusiform ovary into a short and slender beak, which is 

 abruptly dilated into a cylindraceous-campanulate throat; the lobes 

 very minute. Corolla as in the male flower. Style as long as the 

 calyx : stigma dilated, three-lobed. Berry oblong, nearly an inch in 

 length, not pointed, many-seeded. Seeds flat, smooth, about 2 lines 

 long.
