Utricularia subulata

Higher Taxonomy
Family: LentibulariaceaeView DescriptionDichotomous Key

Common Name: BLADDERWORT FAMILY
Habit: 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[4], 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.
Genera In Family: 3 genera, 330 species: worldwide, especially tropics.

Genus: UtriculariaView DescriptionDichotomous Key

Common Name: BLADDERWORT
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[4], 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.

Utricularia subulata L.
NATURALIZED
Habit: Creeping in wet substrates. Stem: creeping in wet substrates, thread-like, with leaves, bladders; winter buds 0. Leaf: leaves at or above surface, simple, < 20 mm, 1 mm wide, entire, flattened, with bladders or not, tip rounded; marginal bristles 0; petiole narrow. Inflorescence: 1--many-flowered; peduncle 5--25 cm, wiry, 0.3--0.6 mm diam; pedicel 2--10 mm, erect in fruit. Flower: corolla 5--10 mm; lower lip +- 2 × upper, +- = spur; spur narrowly elongate, straight; cleistogamous flowers much reduced, < 2 mm. Fruit: dehiscent by ventral valve. Seed: unwinged. Chromosomes: 2n=30.
Ecology: Moist acid wetlands, introduced with other carnivorous plants by horticulturists; Elevation: < 1200 m. Bioregional Distribution: NCo (Mendocino Co.), possibly elsewhere; Distribution Outside California: eastern United States, Mexico, +- pantropical. Flowering Time: Jun--Sep
Synonyms: Utricularia cleistogama (A. Gray) Britton
