Hab. Canada. About Quebec, and Montreal, and Lake Huron. Mrs. Sheppard; Mrs. Percival; Hr.
Richardson; Hr. Todd.—This seems very closely to resemble H. corymbosum, Willd. punctatum, Lam.);
but that is described as having subacute leaves and lanceolate sepals. I still think it may be the H. corymbosum
of Bigelow: and perhaps the two are not really distinct. It is remarkable for the black dots scattered
over every part of the plant, its compact heads of small pale-yellow flowers, and the small obtuse oalyx-
segments.
5. H. perforatum; caule ancipiti, foliis obtusis ovato-ellipticis pellucido-punctatis,

Hab. Canada, to Lake Winipeg. Hr. Richardson. Frequent in Upper Canada. Houglas.—A small
annual species, with slender erect stems, panided above. Heaves scarcely half-an-inch long.—De Candolle
refers to this species also the H. steUarioides of Humb., a native of the Andes of South America.
8. H. eUipticum; caule erecto herbaceo superne subramoso acute 4-angulo, foliis
ellipticis obtusissimis pellucido-punctatis et obscure fusco-punctatis, corymbis parvis
terminalibus, sepalis oblongis patentibus valde inasqualibus nervosis foliaceis, stylis 2-3
arete in unum coalitis.
Radix reppns atque fibrosa, ut videtor perennis. Caulis erectus, spithamseus ad pedalem et ultra, erectus,
subgracilis, acute tetragonus, superne solummodo divisus, ramulis brevibus plerumque sterilibus. Folia opposite,
unciam sesquiunciam longa, fere exacte elliptica, plana, membranacea, obtusissima, pellucido-punctata
atque superfide subtus prsecipue magis minusve obscure fusco-punctata. Pedunculus aphyllus, terminalis,
dichotome corymbosus, floribus in axillis sessilibus. Catycis foliola 3-5, patentia, imequalia, foliacea, nervosa
atque pellucido-punctata, oblonga vel elliptica. Petala flava, obovata-cuneata, calyce vix longiora.
Stamina numerosa, styli longitudine. Germen ovatum. Siyli 2-3 in unum arete coaliti, subulati, obtusi,
rarius in floribus e dichotomia corymbi in duos vel tres stylos separabiles, basi magis minusve unitos.
Capsula ovato-globosa, calyce patenti persistenti brevior.
Hab. Canada to Lake Winipeg. Mr. Cleghom; Hr. Richardson. Lake Huron. Hr. Todd.—This
Hypericum, of which I can find no description, I only know as a native of Canada. I long ago received
specimens from Mr. Cleghom, and now it has been found by Dr. Todd at Pentanguishene on Lake Huron,
exactly on the borders of the United States; and, by Dr. Richardson it was ascertained to extend its range
as far as the plains of the Saskatchawan, in lat. 54°. It is difficult to say to what division of the genus it should
belong; its unequal calyx allies it with “ Ascyriaf its foliaceous sepals with “ Bathrys,” its habit with
“ Perforaria,” where I have placed it. So much are the styles united, that the flowers may be said to be
monogynous; yet in the axils of the corymb some of the pistils as they advance to maturity are found to
have their styles more or less divided; but I do not observe this to be the case with the upper flowers.
9. H. Scouleri; caule herbaceo ramoso inferne terete superne quadrangulo, foliis ob-
longo-ovatis subcoriaceis venosis impunctatis, panicula corymbosa foliosa, calycibus
ovatis obtusis petalisque triplo longioribus extus nigro-glandulosis, stylis 3 longitudine
staminum numerosorum.
Hab. Abundant in dry gravelly soils and limestone rocks on the North-West coast of America, near
the Columbia. Hr. Scouier; Houglas.—Flowers about the size of those of H. dubium. Petals, stamens, and
styles long, and about equal in length. Leaves of a rigid and somewhat coriaceous texture, turning- brown
in drying, exhibiting no pellucid dots, except in the youngest, and these often mixed with oblong ones.

Hab. Canada, (MRchaux,) most abundant near the southern lakes. Houglas; Hr. Todd; Mrs. Percival.
Mr. Douglas observes that its northern limit is at Lake Winipeg, where it is of diminutive stature.__This is
a beautiful small tree, with smooth bark, streaked with longitudinal white lines, whence in some parts of
the United States it is called Striped Maple, while in others it is named Moose- Wood, from the circumstance
of the Moose-Deer subsisting during severe weather upon its young twigs. The leaves have their lobes
singularly acuminated and most finely serrated. Its buds and leaves are among those of the earliest of the
American trees to announce the approach of Spring; and, when beginning to unfold, are of a delicate rose-
colour, which soon changes to green. The wood is said by Michaux to be white, and used instead of Holly.
Horses and cattle are turned into the woods to feed on the young shoots at the latter end of winter.—Racemes
long. Flowers large.
