Utricularia. | XLVII, LENTIBULACEZ. 297 
1, Utricularia vulgaris, Linn. (fig. 665). Common Bladderwort,— 
The root-like floating branches often 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. Fl. swmmer. A slender variety, with long pedicels 
remaining erect after flowering, and the upper lip of the corolla projecting 
beyond the small palate, has been distinguished as a species under the name 
of U. neglecta, Lehm. It has been found in various parts of England. 
2, Utricularia minor, Linn. (fig. 666). Lesser Bladderwort.— 
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 protuberance. 
Appears to be as widely spread over northern and central Europe, Rus- 
sian 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.667). Intermediate Bladder- 
wort.—Intermediate in size between U. vulgaris and U. minor, and dis- 
tinguished 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 JU. 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. #7. summer. 
The Snowdrop-tree (Halesia) from North America, and the Styraz from 
south-eastern Europe and western Asia, both occasionally to be met with in 
our shrubberies and plantations, belong to the small Styrax family, which 
is entirely exotic. It consists of trees and shrubs, with the calyx often 
. partially adherent to the ovary, the corolla monopetalous, and stamens, 
although inserted on the corolla, usually more or less united together. 
XLVIII. OLEACEA. THE OLIVE FAMILY. 
(Jasminacee, 1st edit.) 
Trees, shrubs, or tall climbers, with opposite (or in a very 
few exotic species alternate) leaves, entire or pinnate, and 
flowers usually in terminal panicles or clusters. Calyx and
