Tue native place of the Verbena mutabilis seems rather enveloped in obscurity : by some it is supposed 
to be indigenous to Peru. It is a beautiful plant, and the most desirable Verbena we are acquainted 
with, as it is at least six months in successive bloom. It is one of those Verbenas that, differing a little 
from the general character of that genus, has received various titles from different botanists : by Pro- 
_ fessor Vahl, in his Enumeratio Plantarum, it is called Stachytarpheta. The present species has been 
recently figured in the Paradisus Londinensis under the title of Cymburus miutabilis, and probably at 
"some future period it may again receive another title: but until we can ‘find some better path to lead 
us into the open plain of Information, we shall keep jogging on in the old beaten track, in preference 
to every crooked turning that may bewilder us into the mazy iabyrinth of affected Science. Qur 
figure was made from a fine plant in the nursery of Messrs, Colville.
