T h is species was brought from Scotland many years ago by
Mr. Dickson, and given to Mr. E. Forster, from whose garden
we had it last autumn. - It is perennial, flowering in the latter
part of the summer. The synonyms of Villars and Allioni
are determined by authentic specimeris, but Haller’s n. 43 a,
we are now certain, is not this plant, though his /3 seems to
come very near it. It is safest to exclude his synonym from
the FI. Brit, altogether, as well as Boccone’s t. 53.
The plant before us differs from H. denticulatum, t. 2122,
with which it was confounded in FI. Brit., in having the leaves
embrace the stem by their rounded dilated base, and in their
singular roughness near the edge, which there forms a bristly
border. These marks are enough to distinguish them. The
Swiss Hieracia are so obscure, and the authors who treat of
them so misquote each other, that it is very difficult to come
to any certainty abort them; but we believe the cydonicefolium
of Villars is Haller’s n. 43 a, and not his n. 45, which is
paludosum. W e have no authentic specimen of Haller’s
n. 43 j3, which deficiency leaves us in doubt concerning it.— ■
B y several dried ones, sent from Mr. G. Don, we believe the
Hawkweeds of Scotland are not yet all determined, but the
greatest attention to living plants can alone enable us to reduce
them to order. When that is accomplished, we have ample
materials for settling their synonyms.
