at the base; the cauline ones lanceolate, nearly entire ; lobes of the calyx
ovate, broad, as long as the tube or at length shorter; petals ovate, scarcely

40. S. Cymbalaria (Linn. 1) : stems numerous, weak, few-flowered,
pubescent and glandular above ; leaves reniform, petioled, crenately lobed;
flowers about 3 ; bracts half the length of the pedicels; sepals oblong;
petals obovate, much longer than the calyx; styles approximate at the base,
diverging at the summit. Seringe, in DC. prodr. 4. p. 44.
Chamisso’s Island, and the Island of St. Lawrence, Chamisso, ex Sternb.
{Linncea, 6. p. 555.)—This is probably the same with the Siberian plant, of
which we have specimens from the Russian botanists; but it can hardly be
the S. Cymbalaria of Don (or of Linnaeus ?), a Grecian plant, which is said
to have “ Flores parvi, aurei, petalis acutis.”
41. S. petreea (Linn.): annual, glandularly hairy; leaves fleshy, 3-lobed;
the radical ones cordate, on rather long „petioles, with the lobes incised;
cauline ones somewhat cuneiform; the uppermost entire ; peduncles and
calyx hispid with glandular hairs; segments of the calyx oblong, erect;
petals obovate, retuse. Hook.—Linn. spec. (ed. 2) p. 578 ; Jacq. ic. r'ar.

Alpine rivulets upon the Rocky Mountains, Drummond ! in Hook.
§ 9. Caudex above the ground rwne : stem annual, more or less leafy: calyx
campanulate, coherent with the base of the ovary ; the segments spreading:
stamens mostly 5.—Isomeria. 42
42. S. Jamesii (Torr.): glandularly puberulent; radical leaves on rather
long petioles, reniform-cordate, smoothish, obscurely veined, crenately toothed
or lobed; cauline ones very few, the uppermost bract-like, cuneiform;
raceme compound; calyx (and pedicels) glandular, purplish; the tube
campanulate, cohering at the base with the ovary ; the segments triangular-
ovate, rather acute, about the length of the unguiculate orbicular or spatulate
petals ; stamens 10.—Torr.! in ann. lyc. New York, 2. p. 204 ; Hook. ! jl.

Dry rocky places on the Rocky Mountains in lat. 41°, Dr. James! and
farther north in the same range, Drummond !—Rhizoma thick. Stem 2-4
inches high, 5-10-flowered; the branches of the paniculate raceme subtended
by leafy bracts. Flowers large. Petals purplish. Filaments scarcely longer
than the oblong anthers.—The form and size of the petals seem to be quite
variable in this species. In the specimens collected by Dr. James they are
orbicular with very slender claws, as originally described, at first a little
longer than the calyx-segments, but at length considerably exserted. As
described and figured by Hooker from Drummond’s specimens, they are
small, spatulate and acute. In our specimen, collected by Drummond, the
petals are not uniform in shape, but are more commonly obtuse.
43. S. Richardsonii (Hook.): stem glandular, pubescent near the summit;
leaves on long petioles, orbicular-cordate, crenately lobed, veiny, the margins
and veins beneath beset with pedicellate glands; raceme compound, somewhat
spicate ; the pedicels and lanceolate bracts glandular; petals obovate-
elliptieal, with short claws, nerved, very acute, nearly twice the length of
the acuminate segments of the calyx ; stamens 5. Hook. ! jl. Bar.-Am. 1.

Arctic Sea-shore, near Mackenzie River, Dr. Richardson. Kotzebue’s
Sound, Capt. Beechey!—A robust and handsome species, often a foot high.
The flowers are large and apparently white.
44. S. elata (Nutt, mss.): “more or less hirsute with long brownish hairs;
stem leafy, simple, tall and erect, smooth and cymosely branched above;
the branches slender; leaves cordate, roundish, 5-7-lobed, acutely and in-
cisely serrate, petioled, with tufts of long chaffy hairs in the axils; peduncles
bracteate, viscid ; segments of the calyx lanceolate, acute, scarcely half
the length of the cuneate-oblong obtuse petals ; stamens 5.
“ In wet places near Chenook Point at the estuary of the Oregon, rare.
June.—A very remarkable robust species, 12-18 inches high, with acutely
lobed many-cleft veiny leaves, similar to some species of Ranunculus ; the
incised and unequal small serratures usually terminated by short hairs. The
slender axillary flower-branches arise near the summit of the stem, and
terminate in loose few-flowered cymes of small white pedicellate flowers.
Styles 2, rather short: about half of the ovary free.” Nuttall.—We have
not seen this species.
45. S. ranunculifolia (Hook.): somewhat glandularly pubescent, slender;
lower leaves on very long petioles, reniform, 3-parted, the segments broadly
cuneiform and incisely lobed; those of the stem few ; flowers corymbose,
pentandrous; petals obovate, twice the length of the glandular acute segments
of the calyx. Hook. jl. Bor.-Am. l.p . 246, t. 83.
Common on the high grounds around the Kettle Falls of the Oregon, and
on the Rocky Mountains, Douglas— Stem nearly a foot high, slender.
Petioles of the radical leaves bulbiferous at the base. Corymb compact.
Flowers white, as large as in S. stellaris. Hook.—This species is only known
to us through the figure and description of Hooker. Possibly a species of
Boykinia; but it cannot be our B. occidentalis.
46. S. ? Sullivantii: somewhat glandular; stems or scapes declined,
slender, 1-2-leaved ; radical leaves reniform-orbicular, incisely dentate with
numerous broadly ovate teeth, and slightly lobed, nearly glabrous, veiny, on
long petioles; cauline leaf similar but smaller, or the upper one nearly
sessile and bract-like; flowers paniculate-cymose ; calyx glabrous, coherent
only with the base of the ovary; the segments ovate, rather obtuse, scarcely
half the length of the oval-spatulate distinctly unguiculate slightly acute
petals; stamens 5, shorter than the calyx.
