RANUNCULACEA3.

[Ranunculus.

Hab. Cape Charles, Labrador. Captain Robinson, July, 1820.—The specimen gathered in Labradorwas given to me, with several other very ftrtdfbsting plants from that country, by the late Mr. Morrison.It is undoubtedly the same as the European plant, hut scarcely exceeding two inches in height. It ispossible that the seeds may have been brought to Labrador by the Missionaries ; but as I have no means ofascertaining this point, I think it safer to introduce the plant as a doubtful native of N, America , than toomit it altogether.

Hab. In water, in the eastern, central, and prairie districts, from the United States to near the Arctic Sea ,lat. 68°. Dr. Richardson. Drummond. —In all the specimens gathered during the Land Arctic Expedition,the lloating leaves are wanting. The var. y., as De Candolle observes, grows short and tufted, having itsnaturally submerged leaves (loft by the evaporation of the water,) capillaceo-multilid, and more rigid than asif constantly under water. The figure in Schkuhr admirably represents this kind of loaf. Var. 2. stagnatilisis remarkable for its distantly-placed leaves, having an almost orbicular circumscription.
