296 THE PINGUICULA FAMILY. (Utricularia, 
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. 
A considerable eenus, dispersed over nearly the whole world, 
Bladders interspersed with the leaves. 
Flowers of a rich yellow, about 6 to 8 lines long. Spur conical. 1. UV. vulgaris. 
Flowers of a pale yellow, not 4lineslong. Spur very short . 2. UJ. minor. 
Bladders on separate branches from the leaves : : é . 3&8. U. intermedia. 
1, Utricularia vulgaris, Linn. (fig. 667). Common B.—The root- 
like floating branches extend to a length of 6 inches to a foot or more, 
bearing numerous capillary, much divided leaves, from 4 to 1 inch long, 
and more or less interspersed with little green vesicles. Flower-stems 
6 to 8 inches high, bearing a few rather large yellow flowers. Bracts 
at the base of the pedicels, and lobes of the calyx, broad and thin. 
Corolla with a short, conical, more or less curved spur; and a broad 
convex palate ; the upper lip very short, scarcely projecting beyond the 
palate; the lower lip much longer, thrown back from the palate; the 
lateral lobes turned downwards. 
In deep pools and water-channels, in Europe, Asia, and America, 
from the Arctic Circle to the tropics. Widely distributed over Britain, 
although not a common plant. /l. summer. A slender variety, U. ne- 
glecta, Lehm., with long pedicels remaining erect after flowering, and 
the upper lip of the corolla projecting beyond the small palate, has 
been found in the south-eastern counties of England. 
2. Utricularia minor, Linn. (fig. 668). Lesser B.—Differs chiefly 
from U. vulgaris in the small size of all its parts. The floating branches 
are very slender, those of the flowering plant usually 2 or 3 inches long, © 
but when barren often longer, and intricately branched; the leaves 
small, very fine, very few forked lobes, and seldom more than 1 or 2 
bladders to each, or often without any. Flowers scarcely more than 
half the size of those of U. vulgaris, of a pale yellow, with the lower 
lip much flatter; the spur usually reduced to a short, broad pro- 
tuberance. 
Appears to be as widely spread over northern. and central Europe, 
Russian Asia, and northern America as U. vulgaris, but not extending 
so far to the southward. Rather common in Britain. Fl. summer. 
3. Utricularia intermedia, Hayne (fig. 669). Intermediate B.— 
Intermediate in size between U. vulgaris and U. minor, and distinguished 
from both by the leaves crowded into tufts at the ends of branches 
without bladders, the bladders being few, and placed at the ends of 
leafless branches, Flowers of a pale yellow, larger than in U. minor, 
with a much more prominent spur. 
In central and western Europe, much more rare than the preceding 
species. Local in Britain, indicated in Dorsetshire, Hants, Norfolk, 
and Westmoreland, whence it extends to the north of Scotland ; found 
also in Ireland. Fl. summer. 
The Snowdrop-tree (Halesia) from North America, and the Styrax from . 
south-eastern Europe and western Asia, both occasionally to be met ~ 
with in our shrubberies and plantations, belong to the small Styrax
