896 Lentibulariaceae. 
winged, usually very small, exalbuminous. Embryo undifferentiated, 
with or without obscure protuberances (the beginnings of the primary 
leaves), rarely with a plumule of 9—12 more or less subulate 
primary leaves. — Rootless, aquatic or terrestrial or epiphytic herbs, 
nearly always provided with minute bladder-like organs for the 
capture and digestion of small organisms; annual or perennial with 
or without a resting season; the aquatic species reproducing them- 
selves frequently from special resting buds (hibernacles) and the 
epiphytic sometimes from tubers. ‘Terrestrial and epiphytic species: 
Primary axis developed, terminating with an inflorescence, producing 
at the base above the small primary leaves a rosette of foliage- 
leaves (rarely a solitary foliage-leaf) and non-axillary stolons, leaves 
and stolons showing no definite sequence and passing sometimes 
into each other. Stolons groning with inrolled or straight tips, 
either developed as rhizoids (growing downwards into the substratum 
and resembling roots) or creeping on or close to the surface of the 
substratum, often among moss and dwarf herbage, more or less 
branching and producing bladders, foliage-leaves and, from certain 
of their axils, flowering or barren (and then much stunted) shoots 
with a more or less developed basal tuft or rosette of leaves and 
stolons. Leaves petioled, normally always entire, linear to orbicular 
or reniform, rarely peltate, often decayed at the time of flowering, 
frequently producing bladders, stolons or adventitious shoots. Aquatic 
species: Primary axis arrested (according to Goebel), producing above 
or among the primary leaves one or several stolons. Stolons floating 
in still water or creeping on mud, rarely attached to stones and 
rocks in running water, often very long, growing with inrolled tips, 
branching; branches either all alike and resembling the primary 
stolons, producing from the flanks alternate or occasionally sub- 
opposite leaves and axillary or juxta-axillary inflorescences or branches 
heteromorphic, some of them growing downwards and producing 
only much reduced leaves and bladders. Leaves more or less 
divided into filiform or capillary segments; primary segments of 
the large-leaved species often imitating a whorl or half-whorl of 
pinnate leaves (rays), pinnae more or less 2-seriate on the some- 
times broadened midrib, usually forked at the base, each division 
again divided, 1—2 outer rays sometimes replaced by a hyaline 
cordate or reniform or more or less divided auricle, resembling a 
stipule; all or certain leaves or the leaves of certain branches pro- 
ducing bladders, usually in the place of leaf-segments. Bladders 
globose to ovoid, stalked, with an oblique subterminal or subbasal 
mouth, closed by a membranous flexible valve and a_ turned-in 
thickening (chin) of the lower rim, sometimes produced into an 
upper or an upper and Jower lip, ciliate, fimbriate or furnished with
