Pinguicula.| XLVII. LENTIBULACEZ. 295 
Flowers violet-purple, often mre Spur long, slemien, and pea 
straight . Ll. P. vulgaris. 
Flowers yellow or pale- coloured. Spur small, conical or curved. 
Spur very short, nearly straight. Middle lobe of the lower lip 
of the corolla much larger than the others. Upper lipshort 2. P, alpina, 
Spur curved. Lobes of the lower lip of the corolla Bey cana, 
and scarcely longer than the upper lip. . 3 P. lusitanica. 
1. P. vulgaris, Linn. (fig, 664), ee puncte spreading, 
ovate or broadly oblong, of a light green, somewhat succulent, and 
covered with little crystalline points, which give them a wet, clammy 
appearance. TF lower-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 Hurope, 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 
Kurope, where, however, it passes gradually into the commoner form. 
[It has been naturalised in the vicinity of Penzance. ] 
2. P. alpina, Linn. (fig. 665). Alpine B.—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 Kurope 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. 
Fl. early summer. 
3. P. lusitanica, Linn. (fig. 666). Pale B.—Leaves of P. vulgaris, 
but 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. 
Il. UTRICULARIA. BLADDERWORT. 
Some exotic species are marsh plants, either leafless or with entire 
radical leaves and 1-flowered peduncles ; the European ones are 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. Flowers in the terminal raceme, on a
