Leaves connate basally, with scarious sheath 0.2-0.3 mm, sessile; blade 1-veined (prominent proximally), oblanceolate to spatulate, 2-6 × 0.8-1.8 mm, succulent, margins thickened, minutely scarious-granular, ± shiny, ciliate in proximal 2, apex ± obtuse, sometimes pustulate, glabrous; axillary leaf clusters absent. Inflorescences terminal or axillary, open, leafy, 1-4-flowered cymes in distal leaf axils. Pedicels erect or nodding in fruit, 2-12 mm, retrorsely pubescent. Flowers: sepals green or distally purple, 3-veined (2 lateral veins 2 times as long as midvein), sometimes keeled, narrowly lanceolate (herbaceous portion narrowly lanceolate), 3-4 mm, to ca. 5 mm in fruit, apex ± acute, not pustulate, glabrous or sparsely stipitate-glandular; petals obovate, 5-8 mm, 1 3-2 times as long as sepals, apex acute to rounded. Capsules tightly enclosed by calyx, narrowly ellipsoid to cylindric, 3-5 mm, ca. equaling sepals. Seeds 15-20, black to reddish brown, reniform, compressed, 0.8-0.9 mm, shiny, low-tuberculate. 2n = 40.
