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

lat. 68°. Dr. Richardson. Drummond.—In all the specimens gathered during the Land Arctic Expedition,
the floating leaves are wanting. The var. y., as De Candolle observes, grows short and tufted, having its
naturally submerged leaves (left by the evaporation of the water,) capillaceo-multifid, and more rigid than as
.if constantly under water. The figure in Schkuhr admirably represents this kind of leaf. Var. X stagnatilis
is remarkable for its distantly-placed leaves, having an almost orbicular circumscription.
