Mr Nuttall is quite correct in making this western Ozalis different from the O. Acetosella of Europe and
Eastern America. It is much larger, the young leaves and buds and the petioles, peduncles, bracteas and
calyx, and underside of the leaves and their margins, are clothed with ferruginous hairs. The description in
Hook. Fl. Bor. Am., of O. Acetosella, belongs exclusively to that plant : the North-western specimens, and
the remarks on them, belong to O. Oregana. It was first found by Mr Menzies in California.

In its flowers this bears a great resemblance to the preceding ; but the leaves are very different, much less
strongly nerved, and the prominent angles of the stem are wholly wanting. The ovary, too, is smooth, and
does not present three projecting lobes as does that of C. t
4. C. sorediatus; ramis teretibus resinoso-verrucosis, ramulis patentibus subsericeis,

pa rum longioribus, (floribus casruleis).
I The short dense glomerules of flowers resemble those of the first species ; but these flowers are blue.
The germen, too, is without lobes. The branches are copiously studded with resinous warts; in the more
exposed parts of the stem, frequently forming lai^e patches.
5. C. iniegerrimus ; glaber, ramis subangulatis p arce resinoso-viscosis, foliis 3-costatis

A very distinct species, with quite entire leaves,'and very long narrow panicles of white flowers. Except
on the very youngest leaves or branches, there is no appearance of pubescence on the plant. Ovary without
projecting lobes.

We agree with Messrs Torrey and Gray in thinking that C. macrocarpus, Nutt, (which is certainly our
original Rhamnus ? cuneatus), and the C. cuneatus, Nutt., constitute in reality but one species, differing as
they do almost exclusively in the colour of the pubescence. Both have the same balsamic odour. The authors
just mentioned are likewise disposed to consider^the C. vermcosus of Nutt., in Torr. et Gr. 1. c., as another
var. o f C. cuneatus.

Tills species has a fragrant and somewhat resinous smell.

1. ThermopAs macrophylla ; caule angulato, petiolis calycibus ovariisque hirsutissimis,
foliis trifoliolatis, foliolis obovato-ellipticis u trin q u e acutis supra glabris subtus pubescentibus,
stipulis maximis (biuncialibus) ovatis acutis.
Leaflets 4 inches long. Calyx angled, deeply 2-lipped i upper lip ovate bidentate, lower fl-partite, the
segmeiils lancookto-subulate. Stamens 10, free. Ovary linear, densely sericeo-villoas, on a short glabrous
sti°pes. A very fine and distinct species, with apparently white, but probably, when recent, yellowish flowers.
Leaves much longer than in any hitherto known species.
