Spec. Char., ^c. An evergreen tree of middle 

 size, with a bushy head. Branches terminated 

 bv 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, 

 size of a plum, full of white milky juice. 

 {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 Tau.sif and 8ur ; 

 where it is a tree, growing to the height of 

 from 1.5 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 

 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.
