A shrub about 4 feet high ; branches stiff, and ultimately, in consequeuce of the peeling off of the bark, 
becoming white ; leaves of a lively green, about an inch or 1^ inches loug, and half au inch broad ; corolla 
scarlet ; capsule tctraspcrmous. — The calyx is not so deeply cut as is the case in the Peruvian species, but 
in other respects the plant agrees well witli the general character and habit of the genus.

S. salvi(Bjlora and S. rostrata agreeing with each other in the most essential particulars, and my speci* 
mens from the Sierra Madre fomiing a complete transition "between them, I have little hesitation in uniting 
them under the oldest name. The leaves in my specimens are mostly quite entire, as they are stated to be 
in the true S. rostrata^ but some show a tendency to become repando-crenate, as Nees says they are in the 
form collected by Humboldt aud Bonplaud under the luime of *S', sahiajlora. The upper lip of the corolla 
is in all my specimens bidentate ; the flowers are pale-blue,
