Flowering shoots erect, simple, 5–10 cm, (sometimes papillose distally); leaf-blades oblanceolate-elliptic, oblanceolate-oblong, or spatulate, base short-spurred; offsets not formed. Inflorescences 3-parted cymes, (4–) 10–27-flowered, 1–3-branched, sometimes monochasially; branches ± arched, spreading, or sometimes recurved, sometimes forked; bracts similar to leaves, smaller. Pedicels 1–3.5 mm. Flowers 5-merous; sepals erect to spreading, distinct basally, yellow-green to yellow, lanceolate-linear or clavate-oblong, unequal, 4.5–12 × 1.4–2.6 mm, apex acute or obtuse, (papillose); petals erect, curving upward distally, distinct, rarely slightly connate, white streaked with pink, lanceolate-elliptic, not carinate, 5–8 mm, apex obtuse, with minute mucronate appendage; filaments white; anthers purple or brown; nectar scales yellow or creamy white, square.
