184 ARBORETUM ET FRUTICETUM BRITANNICUM. 
green shrub or low tree, of very vigorous growth ; so much so, in a young 
state, that, from the shoots not being matured, they are frequently killed down 
to the ground, and the foliage more or less injured. Notwithstanding this, the 
aristotelia frequently flowers, and even ripens fruit; and, in all probability, 
if the tree were planted in dry and rather poor soil, so as to grow slowly, and 
not make more wood every year than it could ripen properly, it would attain 
a large size, and form a very handsome hardy ever- 
green shrub or tree. The plant grows vigorously in 
any common garden soil, producing shoots 3 ft., 4 ft., 
or 5 ft. in length when young ; and it is readily pro- 
pagated by cuttings or by layers. 
Other Species of Avistotélia,— One has been raised 
in the Chelsea Botanic Garden, from South American 
seeds, which Mr. Dillwyn found to stand the winter 
of 1837-8 better than A. Macqui. 
a Azdra dentata R. & P., Don’s Mill. i. p. 257. 
(Bot. Reg. t. 1788., and our jig. 277.) is anevergreen 
shrub or low tree, growing to the height of 12 ft. in @ 
Chili. It,stood 9 years in the Hort. Soc. Garden, ‘ q " 
against a wall, and, though killed by the winter of anes Rane de tite: 
1837-8, it may yet ultimately prove tolerably hardy. 
A. integrifolia, if a different species, may possibly be found hardy also.
