north-west coast of America. From this last source the 
drawing in the Fora Americe Septentrionalis was also taken. 
It is probable that the specimens in Captain Lewis's 
Herbarium were of the plant now under consideration ; 
but it is also certain that those of Mr. Menzies belong to 
a very distinct species. Hence it seems that Pursh con- 
founded two plants under the same name. That he 
intended to call Captain Lewis’s plant B. aquifolium, 
there can be no doubt; but it is equally certain, that in 
consequence of his having figured Mr. Menzies’ species, 
the world now applies the name to the latter. This being 
the case, it has become necessary to distinguish the former 
by a new name, which has been suggested by its singular 
property of creeping at the root; a habit peculiar to this 
species among Berberries. 
A hardy, evergreen shrub, flowering in April; propa- 
gated, but with difficulty, by its creeping roots. Branches 
short, stiff, erect. Leaves evergreen, sometimes ternate, 
more frequently of two or three pairs, with an odd one; 
leaflets ovate, roundish, with spiny teeth, glaucous on each 
side, in no degree shining. Racemes terminal, fascicled, 
diffuse, arising out of scaly buds. Lowers yellow.
