stouter, variously shaped processes (tentacles). Inflorescences race- 
mose, bracteate, peduncled, those of certain aquatic species held 
above water by a whorl of modified spongy leaves (floats); lower 
bracts often barren, adpressed; bracteoles 2, at the base of the 
pedicel, or 0. 
Species over 100; mainly in the Tropics of both hemispheres.

p- 113 partly. — A submerged, aquatic herb floating close to the 
surface. Stems up to over 30 cm long, filiform to more than 1 mm 
in diam. Leaves heteromorphic; normal leaves from a few lines 
to more than 1 cm apart, rarely subopposite, 3—6-partite, auricled, 
rays up to 214/, cm long, finely filiform or dilated and up to over 
2mm broad, auricles solitary or paired, adpressed to the axis, 
orbicular-cordate to reniform with a narrow sinus, 6—9 mm across, 
hyaline, delicately ciliate-dentate; pinnae up to 9 mm long, usually 
fureate from near the base, ultimate segments capillary, minutely 
setose, with or without bladders; bladders usually solitary, from the 
lower part of a pinna, obliquely globose-ovoid, 2—1 mm in diam., 
mouth lateral, truncate, oblong, naked or with 2 setiform antennae; 
float leaves in a false whorl of 6 (rarely fewer or more) or irregularly 
approximate, 2'/,—5'/, cm below the lowest flower, linear-oblong 
to oblong in outline, terete, 20—22 mm long, 2!/,—5'/, mm in 
diam., with short or long pinnae near the apex. Raceme few- to 
many-flowered; peduncle below the floats 5—9 cm long or occa- 
sionally very short, slender; bracts broad-ovate, obtuse, up to almost 
2mm long; bracteoles 0; pedicels 2—2'/, mm long, filiform and 
obliquely erect when in flower, then spreading or recurved, with 
gradually widening wings passing into the wide base of the mature
