It is generally believed that the word Berberis, 
with some modification, was used by the Arabian 
alchymists, and applied to a wild fruit ; and but 
little doubt exists that the berries mentioned by 
Asiatic authors were those of the Barberiy which 
we now cultivate. 
The present rare and beautiful evergreen species 
of Barberry was raised in the London Horticultu- 
ral Society’s garden, from seeds sent home by the 
Society’s collector, Mr. Hartweg; who, it appears, 
found it between Zacatecas and San Luis de Potosi ; 
where it greatly abounds; and with Opuntias and 
Yuccas covers a large tract of countiy. Its trifoli- 
ate leaves are a novelty in this genus; they have 
a glaucous hue, spiny, and prominently marked 
with pale veins. Sufficient attention has not been 
paid to the many newly-introduced Barberries. 
Many, like the present, are evergreen, and suitable 
ornaments for the flower garden and shrubbery. 
The Berberis empetiifolia, a prostrate one, is ad- 
mirably adapted, by its habit, for spreading over 
rock- work or stone boi'ders, and it increases rapidly 
by offsets.
