W e are happy to add another new plant to the British Flora,
through the kind communications of Mr. J. T. Mackay, who
gathered it by the sea-side at Rinville, Cunn'amara, in the west
of Ireland, in the autumn of 1806. This is the Turritis alpina
of Linnaeus, agreeing with his original Gothland specimens,
which he once took for a variety of T. hirsuta, but described
as a new species in his Syst. Vegetabilium. The synonym of
Reynier (and consequently of Schleicher and Willdenow) is
determined by the very specimen sent to the former by Favrod,
and now in my hands, together with the entire collections of
both these learned Swiss botanists, the legacy of my lamented
friend Davall.
The root seems probably biennial. Stem one or more, from
2 to 12 inches high, simple, erect, leafy, round, smooth.
Leaves all smooth on both sides, more or less decidedly
toothed, fringed with simple or forked, scattered, spreading
hairs, a few of which are often clustered into a little tuft or
beard at the tips; the radical leaves obovate, often reddish;
the others elliptical, half-clasping the stem. The more evidently
the leaves are toothed, the less they seem to be fringed.
Flowers white, in a simple corymbus, very soon becoming a
long cluster of linear, narrow, rugged, obscurely quadrangular,
shining pods, each crowned with the very short conical style
and capitate stigma.
