Bentham. Plant. Hartweg. p. 34. no. 268. 
To the pinnated, or ash-leaved, Berberries, formerly mis- 
called Mahonias, Mr. Hartweg has been able to add seven new 
Mexican species, among which is the plant now represented. 
In its native country it forms an evergreen shrub from 
five to six feet high, and is found but sparingly near Cardonal 
and Zimapan, on mountains thinly covered with Pinus 
Llaveana. Mr. Hartweg also met with it near the hot springs 
of Atotonilco El Grande, but nowhere in any quantity. That 
gentleman informs us that it is easily distinguished by its dry 
hard leaves, and pale yellow flowers; and that the wood is 
also of a lighter colour than in any other species. In our 
gardens its appearance is vastly improved, and it will pro- 
bably prove as handsome as others. 
It grows freely when potted in a mixture of sandy loam 
and leaf-mould, to which is added a small portion of rough 
bone-dust. 
Being at present extremely rare, it has not been tried in 
the open border; but the appearance of the plant leads us to 
suppose that it may be at least as hardy as B. fascicularis. 
Up to the present time it has been kept in a cold pit, in the 
garden of the Horticultural Society, where our drawing was 
made in May, 1843.
