Species

Angiosperms > Lamiales > Lentibulariaceae > Genlisea

Characteristics

Terrestrial herb.. Stem short, erect.. Leaves usually few, laxly rosulate, spathulate, usually long-petiolate, total length (l–)2–4(–5) cm., the lamina up to 9 mm. wide.. Traps about as numerous as the leaves.. Inflorescence erect, simple or sparsely branched above, (6–)10–25(–50) cm. high; scape flexuous, terete, glabrous above, usually sparsely hispidulous at or near the base only; flowers (l–)3–10(–15); scales few, similar to the bracts; bracts ovate-lanceolate to linear-lanceolate, acute or acuminate, 2–4 mm. long, glabrous to ± hispidulous; bracteoles similar but narrower; pedicels erect, (2–)5–15(–25) mm. long at anthesis, usually elongating in fruit, glabrous or ± hispidulous, the hairs rarely gland-tipped.. Calyx-lobes subequal, ovate-lanceolate to lanceolate, acute or acuminate, 2–4 mm. long, sparsely to densely hispidulous or rarely glabrous.. Corolla violet, blue, mauve or pink with a greenish or yellowish spur, (6–)10–12(–15) mm. long; upper lip ovate, about twice as long as the calyx-lobes; lower lip larger, broader than long, 3-lobed; palate raised, gibbous; spur cylindrical, obtuse, 1 1/2–2 times as long as the lower lip, ± hispidulous, the hairs rarely gland-tipped.. Filaments falcate; anther-thecae subdistinct.. Ovary ovoid, glabrous to densely hispidulous; style short, indistinct; stigma lower lip semiorbicular, upper obsolete.. Capsule globose to broadly ovoid, 3–4 mm. long, glabrous to hispidulous.. Seeds numerous, ovoid, 0.4–0.5 mm. long, conspicuously reticulate; testa cells ± isodiametric.
