Hab. Vallies in the Rocky Mountains. Drummond.—This fine species of Geranium seems to hold a
middle rank between the American G. maculatum and the European G.pratense: yet it is, I feel assured,
truly distinct from both. In the former, G. maculatum., the leaves are much less divided, the segments
broader, and the peduncles are quite destitute of glandular hairs: in the latter, the leaves are much more
deeply divided, the segments greatly narrower, and more truly pinnatifid. In both, the blossoms are purple;
in ours, the flowers are constantly white, even when cultivated, as the plant is in our gardens, and of a firmer
texture. The G. Tongipes of De Candolle, according to his description, also approaches our plant.

it was, for a long time, confounded.
