342 lxv. lentibulariacete. \_Utriculdria. 
4. P. Lusitanica L. (pale B.') ; spur cylindrical obtuse de- 
curved shorter than the almost equal limb of the corolla, leaves 
veiny and as well as the scape hairy, capsule globose. E. B. 
t. 145. 
Marshy places and wet moors, chiefly confined to the west side of 
the kingdom : never, we believe, found on the east side, and rarely in 
the interior. Plentiful in the Hebrides and Ireland, but most abun- 
dant in the extreme north of Scotland, near Cape Wrath. Tf.. 6 — 10. 
2. Utricularia Linn. Bladderwort. 1 
Cal. bipartite, upper lobe entire, lower often notched or 2- 
toothed. Cor. personate. Style 0 (or filiform and persistent). 
Stigma 2-lipped. Capsule dehiscing irregularly. — Named from 
utriculus, a little bladder. 
1. U. vulgaris L. ( greater B.) ; spur conical straight or 
slightly curved obtuse about half the length of the corolla, the 
upper lip of which is as long as the projecting palate, sides of 
the lower lip recurved, leaves pinnato-multifid remotely spinu- 
lose, vesicles attached to the leaves. E. B. t. 253. 
Ditches and deep pools, not unfrequent. 2f. 6,7. — Hoots much 
branched. Shoots or runners floating horizontally in the water, clothed 
with capillary multifid leaves, bristly at the margin aud bearing little 
crested bladders. Scape erect, 4 — 6 inches high, with 6 — 8 bright 
yellow flowers in a raceme. Lower Up convex much larger and 
broader than the upper one, and having a projecting palate closing 
the mouth. Filaments curved, thick, resembling those of Pinguiculu. 
Anthers slightly cohering. Stigma large, ciliate. 
[ U. neglecta Lehm. a too closely allied species, differing chiefly by 
the upper lip of the cor. three times as long as the roundish palate, 
and anthers quite free, is said by Mr. Babington to be “ apparently a 
native of the Fen Country:” of it we know nothing.] 
2. U. intermedia Ilayne ( intermediate B.) ; spur conical acute 
pressed against the lower lip somewhat shorter than the corolla, 
the upper lip of which is entire twice as long as the palate, 
lower entire nearly flat, leaves tripartite their segments linear 
dichotomous ciliate, vesicles on leafless branches. E. B. 
t. 2489. 
1 The British species of this genus are'all aquatics : and their roots, stems, 
and even leaves, are furnished with numerous membranous reticulate vesicles, 
which, according to Hayne, are filled with water, till it is necessary the plant should 
rise to the surface and expand its blossoms above that fluid. The vesicles are then 
found to contain only air, by aid of which the plant floats : this air again in autumn 
gives place to water, and the plant descends to ripen its seeds at the bottom. Mr. 
Wilson observes, with reference to the bladders of U. vulgaris , that “ they have 
an orifice closed by an elastic valve , opening inwards, and ol much thinner texture 
than the bladder, to which it is attached, where the crest is placed. Aquatic insects 
often enter these bladders, aud are, of course, confined there.”
