Characteristics

Lax shrub, ½-1½ m, branches long, often pendulous then ascending near apex; branchlets 4-lined when young, eventually becoming terete. Leaves subsessile, 2-4½ by 0.6-2.2 cm, oblong to elliptic or ovate-oblong, apex subacute to rounded, usually apiculate, base broadly to narrowly cune — ate, paler below; c. 1 main lateral veins, uniting to form strong intramarginal vein, the reticulate venation not or scarcely visible; glands all pale, punctate. Inflorescence 1-flowered, terminal and on solitary or paired short shoots from up to 14 nodes below, more rarely axillary shoots 2(-3)-flowered with flowers pedunculate. Flowers 2-3 cm ø, plane; buds ovoid, acute or subacute. Sepals (l-)1½-2½ by1-1½(-2) mm, free or connate at the base, broadly ovate or triangular or oblong-lanceolate or subcircular, subacute to rounded, entire, midrib invisible; spreading in flower, ascending in fruit; glands all pale, linear and punctate. Petals bright yellow, 9-15 by 5-7 mm, narrowly obovate, entire, caducous; apiculus absent; glands all pale, linear. Stamen fascicles 5, 6-10 mm long, c. ⅔ as long as petals, each with 6-11 stamens, caducous; anthers bright yellow, gland amber. Ovary 2½-3½Amm, narrowly ellipsoid; styles 5, 4-6(-7) mm, c. 1.3-2 times as long as ovary, completely united; stigmas small; placentas 5, axile with small central lacuna. Capsule 8-11 mm, narrowly cylindric to narrowly cylindric-conic. Seeds dark reddish-brown, c. 1½ mm, fusiform to narrowly ovoid or narrowly cylindric, scarcely carinate, with long terminal appendage sometimes expanded to form narrow wing, very shallowly elongate-reticulate.
