POTENTILLA MONSPELIENSIS L., var. labradorica (Lehm.), n. comb. 
P. labradorica Lehm., Del. Sem. Hort. Hamb. 12 (1849) and Pugil. 
ix. 21 (1851).— This little known plant has been collected recently 
at several stations, not only on the Labrador coast, but about the 
lower St. Lawrence and on the White Mountains. It is a pronounced 
extreme of the common bristly-villous P. monspeliensis, in which the 
pubescence is nearly or quite wanting. The specimens examined 
are all small, some tufted and acaulescent, others simple and becom- 
ing 3 dm. high.
