| 備註: Eng. FOC: Bracts [苞片]and bracteoles [小苞片] basisolute [中間駁], attached just above to below middle - 短梗挖耳草 Bracts and bracteoles basifixed [苞片和小苞片基部著生] - 斜果挖耳草 ENG. FOC: Annuals, terrestrial. Rhizoids and stolons capillary, branched. Traps on stolons and leaves, stalked, ovoid, 0.2-1 mm, with stipitate glands on appendage and mouth margin, mouth lateral; appendage 1, dorsal, subulate, beaklike. Leaves numerous, from peduncle base and stolon nodes, glabrous; leaf blade linear to linear-obovate, 0.3-2 cm × 0.5-2 mm, membranous, veins 3, base attenuate onto petiole, margin entire, apex rounded. Inflorescences erect, 5-44 cm, 1-15-flowered, glabrous; peduncle terete, 0.3-1.2 mm thick; scales[鱗片] 1-12, similar to bracts[苞片]; bracts basisolute[中間駁], oblanceolate, 1.5-3 mm, base cuneate, apex acute. Pedicel erect at anthesis but spreading to deflexed in fruit, 0.2-1 mm, minutely papillose; bracteoles basisolute, ovate-lanceolate, 1-2 mm. Calyx lobes minutely papillose, glabrous; lower lobe suborbicular, smaller than upper lobe, apex retuse; upper lobe ovate-oblong, 2-3 mm, apex rounded. Corolla violet, pink, or white, marked with yellow at throat, 4-10 mm; lower lip broadly ovate, with a basal 4-ridged swelling, apex rounded to emarginate; spur narrowly conic, usually longer than lower corolla lip, apex subacute; upper lip oblong to ovate-oblong, apex retuse. Filaments 1-2 mm, straight; anther thecae ± distinct. Ovary globose; style short; stigma lower lip semicircular, upper lip deltoid. Capsule globose to ellipsoid, 1.5-2 mm, dehiscing by a short longitudinal ventral slit. Seeds obovoid to oblong-ellipsoid[卵球形到長橢圓形], 0.2-0.3 mm; seed coat with prominent elongate reticulations and conic to clavate papillae. Fl. Jun-Jan, fr.
