or two small leaves; the panicle a foot or more in length. Calyx short, pulverulent
glandular. Petals purplish or white, about 3-nerved, small.—
Alum-root.
2. H. caulescens (Pursh): scape about 2-leaved or often naked, nearly
glabrous ; the base and the elongated petioles a little villous with deflexed
rusty hairs; leaves cordate, sharply 5-7-lobed, glabrous (except the veins
beneath); the lobes acute, acutely and unequally toothed, hispidly ciliate;
panicle slender, loose; the peduncles many-flowered ; bracts linear or subulate
; petals linear-spatulate, narrow, about the length of the exserted stamens.—

Carolina, Curtis! May-June.—Leaves more deeply and sharply lobed
than any other species of the United States (resembling some species of Maple)
; the lobes somewhat ovate, acute, divaricate; the teeth mueronate.
Peduncles minutely glandular. Flowers about the size of H. Americana :
calyx short, a little hairy. Petals nearly thrice the length of the calyx-segments,
white.—The specimens from Kamtschatka (in herb. Lamb. !) which
Pursh wrongly refers to the present species, belong doubtless to H. glabra,
Willd, The name of H. caulescens is not well chosen : it was probably
intended to apply in part to the Kamtschatka plant, as the scape in Pursh’s
own American specimen is leafless.
3. II. villosa (Michx.) : scape 1-3-leaved or nearly naked, the lower portion
and the stout petioles very villous with rusty deflexed hairs; radical
leaves (large) roundish-cordate, membranaceous, glabrous above, villous on
the veins beneath, somewhat 7-9-lobed; the lobes short, acute, somewhat
incised, crenate with mueronate teeth,'ci-liate; panicle loose; peduncles filiform,
many-flowered; _ bracts laciniate or cleft at the apex, ciliate; flowers
very small; petals linear-spatulate and extremely narrow, unguiculate,
about the length of the exserted stamens.—Michx.! fl. l.p . 172; Pursh! fl. 1.

Mountains of Maryland! Virginia! and N. Carolina, to the Cliffs of Kentucky
River, Dr. Short! Also Canada, Mr. Goldie, ex Hoolc. July.—A
large and well-marked species; the radical leaves sometimes 8 inches in diameter,
on long stout petioles; the mueronate tips of the teeth attenuate into
a bristle. _ Scape stout, with 2-3 small leaves, or with squamaceous bracts
(stipules) in their stead, tipped with a minute foliaceous lamina. Peduncles
and calyx more or less hairy, but not viscid. Petals almost like the filaments,
white.
4- H. glabra (Willd.): scape 1-3-leaved, or rarely almost naked; leaves
roundish-cordate, acutely 5-7-lobed, incisely toothed, and, with the petioles
and scape, glabrous; the radical ones on long petioles; those of the stem
more deeply and sharply lobed, somewhat incised, on short petioles; branches
of the panicle loose, divaricate; lowermost bracts often leaf-like, the upper
ones linear, mueronate, entire or incised; limb of the petals lanceolate-ovate,
about the length of the claws, nearly equalling the exserted stamens.—

Rhizoma elongated, procumbent, scaly. Scapes slender, 12—18 inches high,
erect or apparently sometimes reclined. Teeth of the leaves, especially the
cauline ones, sharply mueronate. Peduncles and filiform pedicels puberu-
lent and a little glandular. Calyx pubescent with appressed hairs ; the teeth
short, rather obtuse. Flowers scarcely larger than in H. micrantha. Petals
small. Styles at length much exserted. Seeds oblong or oval, minutely
hispid in lines.
5. H. micrantha (Dougl.): scape nearly naked, the lower portion and the
petioles very villous with long spreading reddish hairs; leaves roundish-cordate,
slightly and obtusely iobed, mucronately crenate; panicle loose, vir-
gate; the bracts of the lower branches leaf-like, the uppermost setaceous;
petals spatulate-laneeolate, with filiform claws, nearly the length of the much
exserted stamens.—Pougl.! in bot. reg. t. 1302 ; P C .! prodr. 4. appx. p.

exserted: calyx campanulate, with the lobes erect; the throat usually more
or less oblique: petals persistent: flowers large: panicles contracted, or

6. II. pubescens (Pursh) : scape naked, minutely pulverulent-pubescent
and scabrous, the lower portion, with the leaves and petioles, nearly glabrous
; leaves orbicular, cordate, obtusely 5-7-lobed; the lobes short and
rounded, crenulate with very short and broad obtuse slightly mucro-
nate teeth, hispidly-ciliate ; panicle somewhat thyrsoid, with few-flowered
contracted branches; bracts linear-setaceous; petals spatulate, scarcely
unguiculate, veiny (violet-purple), longer than the included stamens, about
the length of the somewhat unequal segments of the calyx ; styles filiform,
at length slightly exserted.— Pursh! fl. 1 . p. 187; PC. prodr. 4. p. 52.

surfaces or a little pubescent beneath: petioles rather short. Scape 8—16
inches high, slender. Bracts entire or laciniate-fimbriate. Flowers about 5
lines in length. Calyx-segments greenish-white; two of them narrower.
Petals minutely erase and undulate on the margins.—The name imposed by
Pursh is not appropriate, as this is usually perhaps the most glabrous species
in the United States.
7. H. hispida (Pursh): scape mostly 1-2-leaved, glabrous; radical leaves
roundish-cordate, rather obtusely 5-7-lobed, crenate with very broad and
short almost retuse mueronate teeth, hispidly ciliate; the upper surface
hispid ; the lower, with the petioles, glabrous ; branches of the panicle few-
flowered ; petals broadly obovate-spatulate, unguiculate, veiny (violet-purple),
