Morphology Leaves
Leaves oblanceolate or oblong, 1–5 cm. long, 3–8(–20) mm. wide, obtuse or rounded at the apex, narrowed at the base, ± succulent and juicy.
Morphology Reproductive morphology Inflorescences
Inflorescences terminal or extra-axillary and lateral along the leafy stems, single, paired or rarely ternate, densely-flowered scorpioid cymes, elongating in fruit to up to 10 cm.; bracts absent; pedicels obsolete.
Morphology Reproductive morphology Flowers Calyx
Calyx lobed almost to the base; lobes ± equal, lanceolate or oblong, 1–1.4 mm. long, ± obtuse, ± accrescent in fruit, fleshy.
Morphology Reproductive morphology Flowers Corolla
Corolla white, mostly with a greenish yellow eye and sometimes a faint pink stripe on the lobes; tube cylindrical, 1–1.5 mm. long, 0.8–1.2 mm. diameter, slightly shorter than the calyx-lobes; limb 1.5–3(–10) mm. diameter, the lobes rounded, 0.6–1 mm. long, 0.8–1.3 mm. wide, ascending or somewhat spreading.
