and coarsely toothed, and often more or less incised ; the terminal lobe 

 little prolonged. The whole shape of the leaf is much like that of 

 the common Grape-vine : the larger ones are 4 inches, the smaller 2 

 inches in diameter. Stipules setaceous, caducous. Flowers solitary 

 in the axils of the leaves at the summit of the branches, where they 

 are much crowded : the peduncles, or rather pedicels (since they are 

 articulated at their insertion), only half or a third of an inch in 

 length, pubescent and sparingly hispid. Leaflets of the involucel 8, 

 setaceous-subulate, rigid in texture, nearly glabrous, spreading, entire, 

 adnate to the base of the calyx, 8 to 10 lines long, about the length 

 of the calyx, persistent, not at all glanduliferous. Calyx very hispid 

 with fulvous spreading hairs, at least when young, five-cleft to 

 below the middle, persistent; the short tube ten-ribbed; the lobes 

 lanceolate, acute, each bearing an oblong dorsal gland on its midrib 

 near the base. "Corolla yellow," turning green in drying; the petals 

 doubtless spreading, pubescent externally, an inch and a half or two 

 inches long. Stamineal column antheriferous for a great part of its 

 length, five-toothed at the apex, straight, not longer than the corolla. 

 Style five-lobed only at the apex ; the short lobes hirsute : stigmas 

 depressed-capitate. Ovary densely villous-hispid, five-celled, with 4 

 to 6 biseriate ovules in each cell. Capsule ovoid, closely invested by 

 the calyx and rather shorter than its lobes, two-thirds of an inch long, 

 silky-hispid with appressed hairs, loculicidally five-valved, five-celled ; 

 the cells 4:-b-seeded. Seeds angled, minutely tomentose at the hilum; 

 the surface scurfy, tcith star-shaped scales. Embryo, &c, as in the 

 genus. 



This is a striking and well-marked new species, apparently of the 

 section Ketmia, which does not resemble any other known to me.
