Habit: Carnivorous by bladders (here treated as modified leaves), into which small organisms are sucked when hairs at opening are triggered [epiphytic]. 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. Fruit: capsule.
Species In Genus: +- 220 species: worldwide, especially tropics, Australia. Etymology: (Latin: little bag, from bladders) Note: 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.
