Pin-
Root biennial (?), fibrous, the fibres thickish, somewhat
downy, simple.
Leaves all springing from the root, ovate, horizontal,
arranged in a stellate form, with the margin rolled
in, yellowish, scattered above with raised
pellucid dots.
Flowerstalks one or two from the same root, erect,
four or five inches high, green, smooth, curyed
at the summit, purplish, glanduliferous.
Flowers drooping, of a beautiful purple- colour.
Calyx two-lipped, externally of a blackish violet colour,
and glandulose, internally green and smooth, the
upper lip tripartite, its segments ovate and concave,
the lower lip two-lobed.
Corolla of one' petal, within beautifully veined, having
white hairs, the margins undulated, two-lipped,
the upper lip (which by the curvature of the
scape appears the lower one) is three-Iobed, the
lobes ovate, obtusely truncate; the intermediate
one emarginate; the lower lip bilobed, the lobes
truncated. The Spur conico-cylindraceous, nearly
as long as the corolla, slightly curved, entire,
(but not unfrequently bifid) at the extremity.
Stamens, Pistil, and Fruit entirely similar to those
of Pinguicula vulgaris.

This truly beautiful species of Pinguicula has been no where found wild in the British isles except in the marshy
ground in the western part of the county of Cork, where it was discovered by Mr. Drummond, Curator o f the Botanic
Garden at Cork.
From this gentleman the specimens from which my figure was taken were received, and I have found the
plant to be easy of cultivation for two years, a t the end of which period it has perished. In size it is very
much superior to the Common Butterwort. The flowers particularly are almost twice as large; they are of a far
deeper purple, strongly veined with darker lines, but whitish a t the base internally. These characters are assuredly
constant; and equally so do I find those derived from the truncated extremity of the lobes, their undulated margins,
and the emarginated middle lobe of the upper lip. In other respects it must be acknowledged that this individual
is altogether similar to the Pinguicula vulgaris.
The circumstance of this plant’s forming little scaly bulbs or buds in the winter after losing all its leaves, is mot
peculiar to this species, but is common to it with the P. vulgaris, as has been observed to me by Mr. Murray of •
the Glasgow Botanic Garden.
