Rhizoids and stolons capillary, simple. Traps on rhizoids and stolons, stalked, ovoid, 0.6-0.8 mm, mouth lateral; appendage 1, dorsal, deeply 2-cleft, fringed with multicellular stipitate glands. Leaves numerous, from peduncle base and stolons, subsessile to petiolate; leaf blade obovate, orbicular, or transversely elliptic, 3-10 × 2-6 mm, thinly fleshy, veins dichotomously branched, base cuneate, attenuate, or rounded, margin entire, apex rounded. Inflorescences erect, 1-15 cm, 1-10-flowered; peduncle terete, 0.2-0.4 mm thick, glabrous; scales few, similar to bracts; bracts basisolute, narrowly ovate to oblong, 1-1.5 mm, glandular, base truncate, margin irregularly crenulate to denticulate, apex subacute to rounded. Pedicel spreading at anthesis but often pendulous and withered in fruit, 2-6 mm, capillary, slightly dorsiventrally compressed; bracteoles similar to bract but slightly smaller. Calyx lower lobe oblong-elliptic, much smaller than upper lobe, apex rounded to emarginate; upper lobe suborbicular to broadly obcordate, 1.5-2.5 mm, apex rounded to emarginate. Corolla white or violet, with a yellow spot at base of lower lip, 3-10 mm or much smaller when cleistogamous; lower lip transversely elliptic to suborbicular, apex 5-lobed; spur subulate, ± as long as lower lip, straight or curved, apex acute; palate fringed with hairs; upper lip subovate, much shorter than calyx, apex shortly 2-cleft. Filaments ca. 0.6 mm, straight; anther thecae distinct. Ovary ovoid to depressed globose; style very short; stigma lower lip semicircular, upper lip obsolete. Capsule globose, ca. 2.5 mm in diam., dorsiventrally compressed, dehiscing by a single longitudinal ventral slit. Seeds obovoid, 0.2-0.4 mm, densely covered with glochidiate processes except proximal end. Fl. Jun-Oct, fr. Jul-Nov. | |
