Mr. Tolmie!—This species cannot be the original S. punctata of Linnaeus
(which is perhaps S. Davurica, Willd. as Fischer suggests), and probably is
not the plant of the second edition of the Species Plantarum ; and hence we
have adopted the name long since proposed by Fischer, who was the first to
rectify the synonymy. The name S. arguta, Don, has the priority, if we
are correct in adducing it here ; but of this there is some doubt. To the variety
with compact inflorescence, we refer the S. Nelsoniana, Don, as well
from the description, as on the authority of Fischer, who has labelled the specimen
in the Banksian herbarium, “ S. semidodecandra, Wormskiold," which
he adduces as a synonym of his S. æstivalis. S. heterantha appears to be a
bulbiferous variety of the same species.—Flowers small : petals 1-nerved, or
occasionally with two indistinct branches. Styles very short.
17. »S', arguta (Don) : leaves roundish-reniform, incisely serrate, glabrous ;
petioles filiform ; scape slender, smooth ; segments of the calyx oblong,
acute.—Don, Saxifr. 1. c. p. 356 ; Seringe, l. c. ; Hook. ! fl. Bor.-Am. 1.
p. 252.
N. W. Coast, Menzies.—Panicle very simple. Flowers white, the size
of those of S. steflaris. Segments of the calyx oblong, acute. Petals oval,
unguiculate, many-nerved. Pistils very short, Don.—Probably S. æstivalis.
18. S. nudicaulis (Don) : leaves réniform, palmate, glabrous ; flowers
paniculate; segments of the calyx acute ; scape naked.—Don, Saxifr. 1. c.
p. 366 ; Seringe, l. e. ; Hook. 1. c.
N. W. Coast, Mr. Nelson.—Scape 4-5 inches high, nearly glabrous.
Lobes of the leaves ovate, mucronate. Flowers as large as in S. rivularis,
white. Calyx and pedicels clothed with glandular hairs. Petals small,
obovate, 3-nerved, a fittle longer than the calyx.
19. S. Mertensiana (Bongard) : scape nearly naked ; leaves roundish, incisely
somewhat lobed ; the lobes slightly 3-toothed ; peduncles glandularly
pubescent ; sepals ovate, rather acute ; petals ovate, acute, with very short
claws, 3-nerved.—Bongard, veg. Sitcha, l. c.p. 141.
Sitcha.—Leaves cordate at the base, and cuneately decurrent into the
pétiole, l i - 2 inches broad. Scape simple, about a foot high. Flowers
panicled : pedicels filiform. Ovary ovate, about the length of the styles.

20. S. neglecta (Bray) : stems numerous, filiform, glabrous, nearly leafless
; radical leaves on long petioles, cuneiform at the base, deeply toothed
at the apex, glabrous ; bracts linear, obtuse, minute ; sepals lanceolate-ovate ;
petals lanceolate, scarcely longer than the calyx. Seringe.—Bray, ex Sternb.

21. S. reflexa(Hook.) ; canescently pubescent; leaves ovate, rather coriaceous,
opaque, incisely serrate, attenuate into a petiole ; scape naked ; panicle
glabrous, compact, corymbose ; petals obovate, marked with two orange
spots, scarcely twice the length of the obtuse reflexed calyx-segments; filaments
dilated or petaloid, often abortive ; ovary free.—Hook.fi. Bor.-Am. 1.

Shores of the Arctic Sea between the Mackenzie and Coppermine Rivers,
Richardson.—“ Together with the harsh and rigid foliage of S. nivalis, the
present species has a panicle more resembling that of S. vernalis; but the
petals have two orange spots similar to those of S. leucanthemifolia, and the
free calyx is at all times remarkably reflexed. Hook.
22. »S'. Davurica (Willd.): very glabrous; leaves cuneate-flabelliform,
decurrent into a petiole, deeply incisely toothed, entire towards the base;
scapes leafless, loosely panicled, bracteate; bracts linear, entire; petals obovate,
bipunctate, nearly twice the length of the reflexed calyx-segments;
filaments often petaloid. Hook.— Willd. spec. 2. p. 645; Don, Saxifr.

Behring’s Straits, &c. Menzies, Chamisso, Capt. Beechey. Alpine rivulets
of the Rocky Mountains, between lat. 52° & 56°, Drummond!—This
and the preceding belong to the section Hydatica, rather than to Micranthes.
The lamina of the leaf is sometimes shorter (as in the figure of Pallas), but
often longer than the petiole, and in our specimen the ovaries are 3 or even
4 in number.
23. S. flab ellifolia (R. Brown! mss.): “ ovaries 3-6, superior; leaves dilated
cuneiform, longer than the petiole, serrate-incised beyond the middle;
scape naked, or with a single leaf nearly similar to the radical ones; flowers
corymbose. ■' -
“ Unalaschka, Mr. D. Nelson, [v. sp. in herb. Banks.']—Radical leaves
numerous, often rather broader than long, nearly glabrous. Scape scarcely
a span high, pubescent, somewhat woolly at the apex; the corymb scarcely
divided. Stamens 10. Petals oblong, with short claws, exceeding the glabrous
calyx.” R. B r.—The description has been obligingly communicated
by Mr. Brown. We are uncertain respecting its proper station in die genus,
but suspect it is nearly allied to the preceding species, in which we observe
3-4 ovaries.
24. & Wolleana: leaves all radical, membranaceous (veiny) oblong, tapering
at the base into a short winged petiole, sinuate-toothed, ciliate; scape
striate, viscous-pubescent above; branches of the panicle rather loosely-
flowered, from the axils of leaflike bracts; pedicels slender; sepals nearly
distinct, glabrous, ovate, obtuse, 3-nerved, reflexed, free from the ovary,
about the length of the oval obtuse petals; styles none.
On a mountain near Bethlehem, Pennsylvania, Mr. Wolle! (in wet
places ?)—Root fibrous. Leaves 8 inches or more in length, thin and membranaceous,
mostly obtuse, coarsely toothed; the teeth near the apex repand,
the others somewhat sinuate. Scape rather slender, 12-18 inches high: the
lower branches of the panicle from the axils of obovate foliaceous bracts.
Petals (small) white with a yellowish spot near the base, slightly unguiculate,
obtuse at each end, with a central nerve, from near the middle of which
two indistinct lateral ones arise. Filaments shorter than the petals, usually
much dilated upwards, acute at the apex: anthers roundish, yellow. Stigmas
minute, sessile.—This plant cannot be the S. erosa of Pursh (which is
doubtless nearly allied to S. Pennsylvanica), nor probably of Don, and
certainly not of Seringe. It has somewhat the habit of S. Pennsylvanica;
but the flowers are those of the present section.
