north-west coast of North America, along the riyer Columbia. According 
to Dr. Lindley, the stem of this species does not grow more than 6 in. or 
8 in. high, and is, in fact, shorter than its leaves. The petioles of the leaves, 
he says, “ are jointed at every pair of leaflets, in the manner of a bamboo 
stem.” The plant is hardy, and will thrive in a shady border of peat soil. 
It was introduced into England in 1822, and may be seen in the London 
Horticultural Society’s garden, but it is not yet extensively distributed. In 
London, plants cost 10s. 6d. each.

Spec. Char., §c. Leaflets 2—3 pairs, 
with an odd one, roundish-ovate, 
opaque, spiny-toothed. Racemes 
diffuse. Root creeping. Filaments 
bidentate. (Don’s Miil., i. p. 118.) 
A small branched evergreen 
shrub, seldom rising higher than 
2 ft., with the leaves somewhat 
glaucous on both surfaces. The 
racemes of flowers are termi- 
nal, numerous, fascicled, diffuse, 
risingfrom scalybuds. The plant, 
in British gardens, produces a 
profusion of rich yellow flowers 
in April and May, but these have 
not yet been succeeded by fruit. 
Found wild on the east side of 
the Rocky Mountains of the west 
coast of North America, and per- 
fectly hardy in British gardens. It is propagated by layers or suckers, 
but does not strike readily; and it has, in consequence, been but sparingly 
distributed. Price of plants, in London, 10s. 6d. each. 
App. i. Additional Species of Mahonia. 
Mahonia nepalénsis Dec., Bérberis nepalénsis in the list in p. 173., 1s an 
evergreen Nepal shrub, from 4 ft. to 6 ft. high, of great beauty, which, if it 
could be introduced, would probably be found as hardy as the American 
species. — M. acanthifolia, if different from the foregoing, would also be very 
desirable. It is said to be a fine pinnated-leaved plant, with round black fruit, 
found on the Neelgherry Mountains of India, at the elevation of 8000 ft. M. 
nepalénsis grows at the height of 5000 ft. and 6000 ft., and attains, in shady 
situations, an elevation of 12 ft. It is also found on the Neelgherries, in 11° 
of north latitude. (2oyle’s Illust.) In the Penny Cyclopedia, it is suggested 
that M. nepalénsis “ ought to be obtained from India at any cost, as it would 
in all probability succeed in this climate. — MJ. tragacanthoides, with not more 
than one or two pairs of leaflets, found along the banks of the river Kur, near 
Teflis ; and M. caraganz/folia, a Chinese plant very like the last, having the 
points of the leaflets hardened into spines; well merit introduction.” (iv. p. 262.) 
A plant is mentioned by Thunberg, under the name of J‘lex japénica, which 
appears to be a Mahonia. It is found in the island of Niphon in Japan, and, as 
it would very likely prove hardy, ought by all means to be procured.
