Annual, perennial herb, carnivorous, of moist or aquatic habitats.
Stem: caudex or stolon, then often with thread-like branches.
Leaf: simple, in rosette, or simple or dissected, emerging from caudex or stolon, with minute, carnivorous bladders ± throughout.
Inflorescence: raceme or 1-flowered, scapose.
Flower: bisexual; calyx lips 2, upper 3-lobed, lower 2-lobed, or lips unlobed; corolla 2-lipped, spurred at base, lower lip flat or arched upward, blocking throat or not; stamens 2, epipetalous; ovary superior, chamber 1, placenta generally free-central; stigma unequally 2-lobed, ± sessile.
Fruit: capsule, round, 2-valved, circumscissile, or irregularly dehiscent.
Seed: generally many, small.
3 genera, 330 species: worldwide, especially tropics. [Rice 2006 Growing Carnivorous Plants. Timber Press] —Scientific Editor: Thomas J. Rosatti.
Key to Lentibulariaceae
Carnivorous by bladders (here treated as modified leaves), into which small organisms are sucked when hairs at opening are triggered [epiphytic].Key to Utricularia
Stem: submersed or subterranean shoots [rarely caudex]; some aquatic species produce 2 kinds of stems, green (in water or at surface; leaves with flattened or thread-like segments; bladders 0–few) and white (generally buried in substrate; leaves 0; bladders many), the latter not always present in poor collections.
Leaf: simple or generally dissected into narrow segments, alternate on stolon, margins often with bristles (visible at 10–30×).
Inflorescence: raceme or 1-flowered, emergent; scape slender or wiry, bracts present.
Flower: calyx lips 2, unlobed; corolla yellow [or not], with red-brown streaks or not, upper lip ± entire, lower entire or 3-lobed, spurred; rarely cleistogamous.
± 220 species: worldwide, especially tropics, Australia. (Latin: little bag, from bladders) [Taylor 1989 Kew Bull Add Ser 14:1–724] Size variable, often unreliable for identification; distinction between stems, leaves uncertain. Glands inside bladders consist of 2 pairs of oppositely directed arms, angles of divergence between which used (at 150× or more) to identify fresh or pressed specimens.
Loosely rooted (rarely free-floating) aquatic or creeping in mud.
Stem: generally of 1 kind, thread-like, with leaves, few bladders throughout; winter buds 0.
Leaf: 2–15 mm, generally 2-parted at base, each part forked again or not, bladders 0(2); ultimate segments 2–6 (8), thread-like.
Inflorescence: 1–4-flowered; peduncle < 20 cm, < 0.8 mm diam; pedicel erect in fruit.
Flower: corolla 6–15(25) mm, lower lip <= upper, spur ± = lower lip, conic.
Fruit: laterally 2-valved.
2n=28. Shallow water, mud, mat-forming at surface of deep waters or not; 10–2300 m. n&c California Floristic Province.
