allied species. Its supposed resemblance to H. rutabulum
has given rise to the trivial name; the nerve of the leaf
being considerably thicker and more obvious than in that
moss: it differs also in the pale slender capsule ; and the
foliage, though more polished and brilliant, is of a much
darker hue. Fruit ripe in November.—W.W.

A NATIVE of Ireland, whence it was introduced to the
garden of the eminent botanist after whom, at Mr. Sabine’s
instance, it has been named; Mr. James Drummond is recorded
by Lindley as the discoverer. Ours are garden specimens.
It is a very distinct species, approaching in the appearance
of the large, oval, downy leaflets to R. pomifera; and,
as in that species, the upper part of the flower-stalk is in-
crassated and ripens with the fruit; but the serratures of the
leaves are less regularly compound, and the glands on the
underside are but few and inconspicuous, and the bush is of
more humble growth, and similar in habit, in arms, and in
the dark red and, in some states, cesious bark, to R. cinna-
momea. The branches, however, are more divaricated, and
the prickles less numerous on the root-shoots, and those on
the branches less generally confined to pairs below the stipules.
Larger prickles with a small dilated base, slightly com
