tree. The root and wood are of a dark yellow colour, and form the yellow 
wood of Persian authors; they are used as a dye, and, being bitter and a 
little astringent, they, as well as the bark, are employed in medicine. (Royle’s 
Hlust., p. 63.) In Nepal, the fruit of this species is dried, like grapes for 
forming raisins, in the sun. A most desirable plant, calculated to produce a 
splendid effect, both when in flower and when in fruit, upon an open lawn. 
As arapid grower, it ought not to be planted near slow-growing shrubs o1 
trees. 
Other Species of Bérberis. —B. Coridria Royle, a species having the same 
general appearance as B. aristdta, has been raised in the Horticultural 
Society's Garden, and there are plants 3 ft. high, but they have not yet flow- 
ered. Platts have been raised in the Horticultural Society’s. Garden, and 
in some nurseries, from seeds received from Mexico and Nepal; but, though 
these have new names, it is not certain that they will all prove new species, 
and therefore we consider it better not to record them till they have flow- 
ered. In Hook. Bot, Mis. vol. iii., B. chilénsis Gill., B. ruscifolia Lam., B. 
corymbésa Hook. et Arn., B. glomerdta Hook. et Arn., and B. Grevilleana Gill., 
are described, or mentioned, as having been, found in South America, and 
Dr. Hooker has specimens of them in his herbarium. Numerous varietics 
of Bérberis vulgaris are raised in the London gardens, under continental names, 
as if they were species, but very few of them are worth keeping distinct.

Gen. Char. Sepals 6, guarded on the outside by three scales. Petals 6, with- 
out glands on the inside. Stamens furnished with a tooth on each side at 
top of the filament. Berries 3—9-seeded. (Don’s Mill.) 
Leaves compound, pinnate, alternate, exstipulate, evergreen; the leaflets 
coriaceous, with the margins toothed or serrated. Flowers yellow. Fruit 
mostly black. — Natives of the north-west coast of America, and also of 
Nepal, and perhaps Japan. 
Though some botanists think that the characters ascribed to this genus, and 
those ascribed to Bérberis, as exhibited in p.41., are not sufficient to keep 
them separate as genera; yet the habits of the species of one, as to the mode 
of growth, foliage, and inflorescence, are so distinct from those of the other, 
as to induce us to adopt the genus Mahonia. The species in British gardens 
are all of comparatively slow growth, and admit but of slow multiplication by 
layers, which require to remain on two years, and scarcely at all by cuttings. 
some of them, however, seed freely, and are readily propagated in this way. 
The seeds of all the species of Mahonia, and also of those of Bérberis, if 
sown immediately after they are ripe, and protected through the winter from 
frost, will come up the following spring.
