nous, above scabrous, on petioles 1' - 2' long. Peduncles solitary, ax- 

 illary, scarcely as long as the petioles. Leaves of the involucre 10, 

 terete, two-lobed at the apex. Sepals joined to the middle, strongly 

 10-nerved, triangular-lanceolate, in fruit closed over the capsule. Co- 

 rolla yellow, 2' - 3' long, turning rose-colored in fading. Capsule 1' 

 long, rather less bristly than the calyx. Seeds very smooth.

2. H. BRACKENRIDGII Gray. (Enum. No. 47.) Shrubby, 3 -4 

 high. Flowering branches rather stout, glabrous, or when young 

 scurfy puberulent with the stellular pubescence of this family, very 

 leafy. Leaves on long petioles (3'' -4' long) membranaceous, nearly 

 glabrous, rounded in outline and subcordate, 5-7-ribbed, 5-7-cleft to 

 the middle or deeper, the lobes separated by acute and very narrow 

 sinuses, somewhat ovate in form, acute or obtuse, coarsely toothed or 

 incised, 2' -4' in diameter. Stipules setaceous, caducous. Flowers 

 solitary in the axils near the summit of the branches, where they are 

 much crowded. Peduncles or pedicels i' long, pubescent and sparingly 

 hispid. Leaves of the involucre 9, setaceous-subulate, rigid, nearly 

 glabrous, spreading, entire, adnate to the base of the calyx, 8" - 10" 

 long. Calyx very hispid with fulvous hairs, 5-cleft to below the mid- 

 dle; the short tube 10-ribbed; the lobes lanceolate, acute. Corolla 

 yellow, pubescent externally, 2' -3' long. Style 5-lobed only at the 

 apex ; stigmas depressed-capitate. Ovary densely villous-hispid, with 

 4 - 6 biseriate ovules to each cell. Capsule ovoid, 5' long. Seeds an-

3. H. ARNOTTIANUS Gray. (Enum. No. 48.) A small tree 10 -30 

 high when full-grown, with a fine globular head, and in flower exceed- 

 ingly showy : glabrous throughout. Leaves ovate or oval, rounded 

 or slightly contracted at the base, 3-nerved (or obscurely 5-nerved), 

 somewhat coriaceous, entire, obtuse or acute, 2' -4' long; petioles 

 I'-li'long. Stipules subulate, caducous. Flowers solitary, termi- 

 nating the branches or in the uppermost axils, on peduncles 6" - 20" 

 long. Leaves of the involucre lanceolate or subulate, entire, only 

 2" - 3" long. Calyx cylindrical or tubular, |' - ] ' long, membranaceous, 

 rather deeply five-toothed, puberulent within, glabrous externally, in- 

 clining to split down on one side with age. Corolla white, the petals

 into a slender tube, about 1' long, which is exserted beyond the calyx. 

 Stamineal column red, very long (5'- 6'), slender, erect, and copiously
