thefiowers, too, are smaller, and the petals singularly long and narrow, their upper or broader part becoming
spirally twisted in the dried state.

Drummond.—I have referred this to the H. glabra of Willd., which appears to come from the same country,
and which differs, according to the short character given, only in the “panicula simplex ,” which-is probably
the case with small or starved specimens.

Hab. On the declivities of low hills, and on the steep banks of streams on the west side of the Rocky
Mountains. Douglas.—This is most allied to the following; but abundantly distinguished by the truncate
base to the leaves, and the spicate panicle, by having less oblique calyces, very short stamens, and by the
absence of petals.

Douglas. Scouler. /3. Shady woods. Douglas.—I have quoted the Tiarella Menziesii of Pursh, with a
mark of doubt, chiefly because he describes the “ raceme filiform and spicate,” which is by no means the case.
Ours is a remarkably distinct species.
