2-lobed; spur conic at base, slender above, obtuse 
or emarginate, appressed to and equalling or ex- 
ceeding the lower lip; capsules 2-23” in diameter. 
In shallow water, Long Island to Florida and Mis- 
sissippi, near the coast. June—Aug. 
4. Utricularia intermédia Hayne. Flat- 
leaved Bladderwort. Fig. 3864. 
U. intermedia Hayne, in Schrad. Journ. Bot. 1800':

Stems creeping on the bottom in shallow water, 
radiating from the base of the scape. Leaves 
alternate, those on some branches or portions of 
branches 23’-7” long, trichotomous at base, the 
rays di- or trichotomously divided, with linear, 
flat, bristly-serrulate segments, and without blad- 
ders, those on other branches or portions of 
branches shorter and root-like, with fewer capil- 
lary segments and a few large bladders up to 
23” long; scapes solitary, 2’-8’ high, 1-4-flowered, 
with 1 or several auriculate scales; pedicels 4-10” 
long, erect-ascending; calyx-lobes 1’-13” long, a

lip broadly triangular, 23-3” long, 33’-4” broad, 
the lower slightly 3-lobed, 5”-6” long and broad, 
the palate prominent; spur conic at base, cylindric 
above, acute, about # as long as the lower lip; 
capsules 13” in diameter. 
In shallow water, Newfoundland to British Co- 
lumbia, south to New Jersey, Indiana and California. 
Also in Europe. May-Aug. Commonly propagated 
by the velvety winter-buds. 
5. Utricularia minor L. Lesser Bladder- 
wort. Fig. 386s. 
Utricularia minor L. Sp. Pl. 18. 1753. 
Stems creeping on the bottom in shallow water, 
4-12’ long, sparingly branched. Leaves alter- 
nate, with few divisions, usually only 4/13” 
long, and bearing 1-5 bladders each; larger blad- 
derless leaves, 1-3” long, with flat segments, 
sometimes occurring on special branches or seg- 
ments of the main stem; scapes solitary, filiform, 
2’-6' high, 3-6-flowered, with 2-5 minute auricu- 
late scales; pedicels capillary, 1-4” long, re- 
curved in fruit; calyx-lobes about 3” long; co- 
rolla pale yellow, the upper lip minute, 1-2” 
long and half as wide, the lower 2’-4” long, the

cate; capsules about 4” in diameter.
