Spokane, Washington, at 600-1,000 meters altitude ; collected by J. B. Leiberg and J. H. Sandberg, in May, 1893. Communi cated by Mr. E. P. Sheldon.
A fine species with leaves strongly resembling those of some of the broader-leaved Planlagos. The plant is very different from anything heretofore known in the genus Saxifrager. It is related to S. intc:crifolia. The broad greenish petals, which are exceeded by the calyx, serve to separate the species from all its relatives.
