Hab. Canada. Michaux.—Dr. Boott’s specimens of " P. sarmentosa of Muhl.,” (and Willd. ?), precisely
accord with Dr. Torrey’s, and with Nestier’s description and figure. It may be a state of P. simplex before
the appearance of the runners, but the leaflets are broader and much paler, and silky beneath.
