296 THE PINGUICULA FAMILY, [Pinguicula. 
and covered with little crystalline points, which give them a wet, clammy 
appearance. Flower-stalks 3 to 5 inches high, with a single handsome, 
bluish-purple flower; the broad, campanulate throat of the corolla 
attached laterally to the receptacle, and projected below into a slender spur 
about its own length; the lobes broad, the 2 upper ones (next the calyx) 
considerably shorter than the 3 lower ones. Capsule ovate, longer than 
the calyx. 
Among mountain rills and on wet rocks, in northern Europe, all round 
the Arctic Circle, and along the mountain-ranges of central and southern 
Europe and Russian Asia. In Britain, chiefly in the western hilly districts 
of England and Scotland, and in Ireland. Fl. summer, commencing very 
early. A large-flowered and very handsome variety, with broader lobes, 
and a long spur to the corolla, and a more obtuse capsule, P. grandiflora, 
Lam., occurs in the bogs of south-western Ireland, and here and there in 
the western parts of the continent of Europe, where however it passes 
gradually into the commoner form, 
2, P. alpina, Linn. (fig. 663). Alpine Butterwort.—Generally a smaller 
plant than P. vulgaris, with much smaller flowers, of a pale yellow or 
slightly purplish colour. The {spur is short and obtuse, the lobes of the 
corolla unequal and broad, the middle one of the lower lip much longer 
and broader than the two lateral ones. 
A very northern or high alpine plant, common in the Arctic regions of 
Europe and Asia, and along the higher ranges of central Europe and north 
Asia. In Britain it has only been found in Skye and Ross-shire, Fi. 
early summer. 
3. P. lusitanica, Linn, (fig. 664). Pale Butterwort.—Leaves of P, 
vulgaris, but usually smaller. Peduncles very slender, with a pale yellow 
flower, tinged with lilac, still smaller than in P. alpina ; the spur always 
much curved, rather larger in proportion than in P. alpina, but much 
shorter than in P. vulgaris ; the lips of the corolla nearly equal in length, 
and the lobes of the lower one almost equal in breadth. Capsule globular. 
A west European plant, common in the bogs of Portugal and western _ 
Spain, and France, and extending to Ireland, the south and south-west of 
_ England, and west of Scotland. 7. all summer. 
II. UTRICULARIA. BLADDERWORT. 
Some exotic species are marsh plants, either leafless or with entire 
radical leaves and 1-flowered peduncles ; the European onesare all floating 
plants, without real roots at the time of flowering, but with long, root-like 
capillary branches or rootstocks, all submerged; their leaves divided into 
short capillary segments, interspersed with little bladders or vesicles, full’ 
of air. lowers in the terminal raceme, on a leafless flower-stem arising 
out of the water from a tuft of the floating branches. Calyx deeply 2- 
lobed. Corolla spurred as in Pinguicula, but the mouth is closed or nearly 
so by the convex palate, the lobes of the lips being turned back. Capsule 
globular, opening in 2 valves. 3 
A considerable genus, dispersed over nearly the whole world, 
Bladders interspersed with the leaves. 
Flowers of a rich yellow, about 6 to 8 lines long. Spurconical 1. JU. vulgaris, 
Flowers of a pale yellow, not 4lines long. Spur very short . 2. U. minor. 
Bladders on separate branches from theleaves . F . . 3. U. intermedia
