3 . Caroliniandm. Walt. 
H. hirsutum ; foliis 
ovalibus, subdenticu- 
latis; pedunculis soli- 
tariis,intra axillaribus 
unifloris; calyce cap- 
sulam superante. 
Hirsute: leaves o- 
val, sparingly toothed; 
peduncles solitary, 1- 
flowered, between the 
axils ; calyx longer 
than the capsule. 
Mich. 1. p. 307. Pursh. 2. p. 364. 
Cistus Carolinianus. Walt. p. 152. 
Root perennial. Stem erect, herbaceous, 8-12 inches high, generally 
purple, variegated with white stellular pubescence. Leaves nearly sessile, 
crowded at the base of the stem, sometimes nearly round, very villous, 
pubescence as on the stem stellular. Flowers few, near the summit of the 
stem, larger than those of any other of our species, bright yellow. Pedun- 
cles nearly an inch long. Calyx 5 leaved, persistent, the two exterior 
leaflets linear, generally expanding ; the three interior, larger, ovate lanceo- 
late, acuminate, 3 nerved, covering the capsule. Petals twice as long as 
the calyx. Filaments numerous (30-40,) attached to the base of the germ, 
unequal, much shorter than the corolla. Germ superior, ovate, glabrous. 
Style very short. Sigima globose, obscurely 3-lobed. Seed numerous, 
small, attached by the base to a central receptacle. 
Grows in dry and moderately fertile soils. 
Flowers May to June. 
This is an ornamental plant, but its flowers, as in this whole genus, 
only expand for a few hours in the morning. 
4. Corymbosum. Mich. 
H. foliis oblongo-o- 
valibus lanceolatisque, 
tomentosis, subtus ca- 
nescentibus ; corym- 
bis multifloris, fasti- 
giatis. 
Mich. 1. p. 307. Pursh. 2. p. 364. 
Leaves oblong oval 
and lanceolate, to- 
mentose, underneath 
hoary; corymbs ma- 
ny flowered, fasti- 
giate. 
Roots creeping? perennial. Stem about a foot high, sometimes 
branching, very tomentose when young, pubescence (as perhaps in all of 
the species) stellular. Flowers very much crowded in the corymb.— 
Calyx villous, about as long as the capsule ; the two exterior leaves long 
and linear. Corolla yellow. The flowers in this species are much smaller 
than those of the H. Carolinianum, but nearly equal in size those of our 
other species. F requently in a corymb, one or two flowers rise conspicuous- 
ly above the rest, and the capsules then become much larger.
