-E i VEN this fpecies of Utricularia is not extremely common,
though more fo than the following. It is perfectly an aquatic;
nor can it poffibly grow out of the water, occurring only in
flagrant ditches and pools, and flowering after Midfummer.
The fibrous floating roots, flightly attached to the mud, are
fuppofed to be perennial. The item likewife floats horizontally
under water, alternately divided into capillary branches, with
briftly leaves bearing little comprefled curved bladders, open
and bearded at the tip, containing a bubble of air, and a drop of
watery fluid, in which, when highly magnified, Dr. Withering
obferved a quantity of extremely minute folid particles. Aquatic
infe&s frequently take up their lodging in thefe bladders.
The ftalk only rifes erect a few inches above the water, and is
rendered confpicuous by its fpike of large handfome alternate
flowers, whofe flower-ftalks and calyx are reddilh or purple,
the corolla of one irregular labiate petal, the fpur conical and
recurved, the mouth clofed, palate prominent, of an orange
colour. Stamina thick and fhort. Germen fuperior, ftyle
fhort; ftigma concave and bearded. See Dr. Withering’s excellent
defeription.
We cannot pofitively determine to which of the varieties
mentioned by Linmeus ( Flo. Suec. & Sp. P I .) our plant belongs
; nor can we learn that any other form of U. vulgaris
than that here reprefented has been found in Britain.
