Hab. North-West America. Abundant near the sources of thè Multnomak River, in sandy soils, growing
under the shade of Pinus Lambertiana. Douglas.—I have retained this in the genus Rhamnus, it being
so named by Mr. Douglas in the Herbarium of the Horticultural Society: but when its flowers and fruit
shall be known, it will probably prove to be something very different, even from the Order Rhamnece. It constitutes
a harsh shrub, from four to twelve feet high, with numerous, stout, rigid, terete, opposite,' subpatent,
and subspiniform branches, very leafy, and clothed with a rusty-coloured down. Leaves, the largest of them
scarcely an inch long, and those oblong, cuneate at the base, while those on the younger parts of the branches
are more decidedly cuneate, and smaller, all of them opposite, bearing clusters of young leaves and branches in
the axils, coriaceous, the margins slightly revolute, entire, the apex obtuse, retuse, emarginate, and sometimes
tridentate, glabrous, and very obscurely obliquely nerved on the upper surface; beneath downy, with
the nerves oblique, close, prominent, brown, and reticulated with transverse veins, the areola of these veins,
when seen under a microscope, are filled with a beautiful, short, dense fascicle of hairs, which hairs originate
in a circle, and all converge towards the centre of the little tuft, lying nearly flat. From the axils of some
of the leaves, and from a terminal pair in others, arises a peduncle ? clothed with rusty-brown hairs, and
bearing a globose bud, or cluster of buds, (apparently of very young flowers,) surrounded by small, rusty,
closely-pressed bractece? But of the nature of these flowers I can make nothing. The whole plant
yields, even when not rubbed or bruised, a balsamic odour like that of some Balsam-Poplars, mixed with
a powerful astringencv, resembling the smell of young Birch twigs.—It is to be hoped that during his
present arduous journey through North-West America, Mr. Douglas will obtain flowering and fruit-bearing
specimens of this singular plant.

Hab. Nootka. Mr. Menzies. Mountains near the coast of North-West America, between the parallels
of -40° and 43° N. lat. ? Douglas.—My character of this is drawn up from Mr. Menzies’s specimen in my
Herbarium. Iu Mr. Douglas’s MSS. he notices a C. grandis from the station above-mentioned, which is
probably the same as the present, although it inhabits a much more southern latitude. Our plant, however,
it must be confessed, differs in no respect from the preceding species, except in being everywhere, even
upon the young leaves, entirely glabrous; whereas C. velutinus has, on the oldest as well as the youngest
leaves, a delicate, short, hoary, and almost white tomentum, clothing their underside.
5. C. thyrsiflora; caule erecto stricto ramisque angulatis, foliis breviter petiolatis
oblongis triplinerviis glanduloso-serratis glabris subtus nervis venisque appresso-pilosis,
paniculis longe pedunculatis axillaribus thyrsoideis inferne foliosis, pedicellis brevibus.

Hab. “ North-West coast of America.” Mr. Menzies, (in Herb. noslr.) New California. Eschscholtz.—
For a knowledge of the name of this very distinct species of Ceanothus, I am indebted to Dr. Chamisso, who
sent me an authentic specimen from California. Whether Mr. Menzies’s plant be from California, or from
a higher latitude, as I rather suspect, from the manner in which its station is indicated, I will not take upon
me to say. The flowers are surrounded by densely imbricated, ovate, and acute bractece, in the state of bud,
but these drop before the blossoms are expanded. The calyx, Eschscholtz describes to be blue, the petals
white. The whole plant turns black in drying.
