 inu'h ionfu-<ion nnd is still sonn' uncertainty res[>ccting this s|)cci(>s and its allies. I/igusca's 

 original dos(ri]>tion (puhlishcd in IHOIi) professedly included specimens l>oth from MonU-'rey and 

 from Vancouver Island, while the plant cultivated in the gardens fiom his seed, and hgured 

 under this name, appears to have heen wholly the Oregon form, which Tui^h afterwards included 

 with the low /?. rrpfns in his description an(i figure of Ji. Aquifnlium. lIuml»oldt and IJonpland 

 afterward applied the name B. pinnata to a Mexican plant, figured hy them, nnd DeCandolle at 

 length included all, the Mexican, Californian, ami Oregon together, under the name Mahonia 

 fascicnlaria. The question of synonymy is most conveniently solved by retaining what haa 

 become the ordinary application of the names, B. fnscicnlari.t being limited to the Mexican spe- 

 cies, which seems distinguishable from the Californian B. pinnata by its more numerous, more 

 ncunnnate, and less shining leaflets.
