Spec. Char., §c. An evergreen tree of middle - . 
size, with a bushy head. Branches terminated y : 
by strong spines. Leaves lanceolate, entire, . 
bluntish, glabrous, paler beneath; the lower - 
ones in fascicles. Flowers lateral, and axil- 
lary, scattered, crowded, sessile. Corolla 
greenish yellow. Fruit dotted with white,

(Don’s Mill., iv. p. 28.) A native of the 
southern parts of the kingdom of Morocco ; 
abundant in woods situated in the southern 
provinces, between the rivers Tausif and Sur; 
where it is a tree, growing to the height of 
from 15 ft. to 20 ft., flowering in July. It was 
introduced in 1711, and is occasionally met 
with in collections. It will stand our winters | 
as a standard, but thrives best when planted i 1015 
against a wall. It is called argan by the | 
Moors, who extract an oil from the fruit, which 
they use at table, and which the Europeans employ in a variety of prepa- 
rations. A large plant against the wall, in the arboretum of Messrs. 
Loddiges, flowers abundantly every year. There are plants in the Horti- 
cultural Society’s Garden, and in the Hammersmith and other nurseries. 
The argania thrives in a sandy loam, and is generally propagated by layers. 
Price of plants, in the London nurseries, 5s. each.
