小花苣苔属 xiao hua ju tai shu
Herbs, perennial, epipetric or terrestrial, rhizomatous, stemless. Leaves few to many, basal; leaf blade puberulent to pilose, base cuneate to cordate. Inflorescences lax or rarely dense, axillary, few- to many-flowered cymes; bracts 2, opposite. Calyx actinomorphic, 5-sect from base; segments equal. Corolla white, yellowish, or purplish, zygomorphic, inside puberulent to glabrous; tube nearly tubular, not swollen, much longer than limb, 3-5 mm in diam.; limb indistinctly to distinctly 2-lipped; adaxial lip 2-lobed, slightly to 2-3 X shorter than abaxial lip; abaxial lip 3(or 4)-lobed, lobes equal or central lobe longer, apex rounded. Stamens 2, adnate to abaxial side of corolla tube near base or above middle, included; anthers dorsifixed, connate by adaxial surfaces, thecae divaricate, confluent at apex, dehiscing longitudinally; connective not projecting; staminodes (absent or)1 or 3, adnate to adaxial or adaxial and abaxial sides of corolla tube. Disc ringlike or 2-lobed. Ovary ovoid, 1-loculed; placentas 2, parietal, projecting inward, 2-cleft. Stigma 1, abaxial, obtrapeziform, rarely linear, undivided to 2-lobed. Capsule straight in relation to pedicel, ovoid to narrowly ellipsoid, equalling to shorter than calyx, dehiscing loculicidally to base; valves 2, straight, not twisted. Seeds unappendaged.
