GATHERED on the Highland mountain of Ben Lawers by
Mr. Dickson; and since by the late Mr. J. Mackay, from
whom we received this specimen. Few plants are less generally
known.
It is perennial, and flowers in May and June. Roots branching
at the top, and bearing several little tufts of lanceolate,
spreading leaves, more or less waved or notched, fringed,
sometimes hairy beneath. All the hairs are quite simple,
except those on the fruit, and point rather upwards. Stalk 2
or 3 inches high, solitary, simple, round, more or less hairy,
naked, except an occasional leaf near the bottom. Flowers
small, in a little corymbus. Calyx spreading, hairy. Petals
white, scarcely notched. Pouch upright, lanceolate, flattish,
a little longer than its partial stalk, crowned with an almost
sessile stigma, and generally clothed with minute, forked,
divaricated, white hairs.
The real D. stellata of Jacquin has starry hairs on the
leaves, shorter pouches, a longer style, and flowers thrice as
large.
We take this opportunity of mentioning that the discovery
of D. aizoides, t. 1271, is claimed by.our obliging correspondent
John Lucas, Esq. of Stout Hall nearSwansea, who informs
us he found it in 1795 near Wormshead, 16 miles west of that
town; but having never mentioned it to his friend Dr. Turton,
the latter justly thought himself the original discoverer.
