Drummond.—This new species of Tiarella has much of the habit of Heuchera glabra ; but the flowers are
smaller, the stem has constantly only one leaf, and that nearly as large as those of the root, and the fruit is
truly that of a TiareUa. I find constantly ten perfect stamens, and about as many apparently abortive ones,
which may be abortive petals. Perfect petals, if any exist, must, be very fugacious, as I have never been
able to detect them.

Hab. “ North-West Coast. A. Menzies, Esq.n-—This, I suspect to be the Heuchera Menziesii of the
present work ; but the character of the inflorescence is at variance with that plant, which leaves me in
doubt on the subject.

Hab. North-West coast of America; A. Menzies, Esq. Common on the coast, and in the Rocky
Mountains on the west side of the ridge. Douglas. Height of land near a large glacier, upon the Rocky
Mountains. Drummond.-—This has very much the habit of our T. unifoliata; but the leaves are constantly
ternate, the leaflets petiolulate, and the stem itself is sometimes a leafless scape, at other times, furnished
with one or two leaves, and the flowers are smaller. The alpine specimens, found by Mr. Drummond, differ
in no respect from those of the coast, except in being smaller. They are glabrous, as are many of those
from the coast, while others are more or less pubescenti-hirsute. Two panicles are occasionally produced on
the same stem.
