Morphology General Habit
Small shrub up to 1·3 m. tall with a long tap-root; young branches greyish-brown, tomentellous, becoming scurfy pubescent and later glabrescent and reddish-brown.
Morphology Leaves
Leaf-lamina 1–6·5 × 0·5–2·5 cm., ovate, ovate-oblong or oblong-lanceolate, acute, obtuse or rounded at the apex, margins ± irregularly serrate, rounded at the base, greyish- or greyish-brown-tomentellous on both sides; petiole 5–15 mm. long, tomentellous; stipules 2–5 mm. long, linear, tomentellous.
Morphology Reproductive morphology Inflorescences
Inflorescences of small cymes crowded at the nodes; cymes 1–3 or rarely more-flowered, with a tomentellous peduncle 5–8 mm. long; pedicels similar, 1–3 mm. long; bracts at the base of the pedicels 2–3 mm. long, forming an involucre, tomentellous, subulate to lanceolate.
Morphology Reproductive morphology Flowers Calyx
Sepals 6–9 mm. long, c. 1 mm. wide at the base, 0·5 mm. wide above, linear, reflexed just above the base, tomentellous outside, with a horn 0·5 mm. long almost at the apex.
Morphology Reproductive morphology Flowers Corolla
Petals yellow, 4–5 × 1–1·5 mm., oblong-oblanceolate, apex rounded or refuse, base ciliate.
Morphology Reproductive morphology Flowers Androgynophore
Androgynophore c. 0·5 mm. long, glands obovate; annulus ciliate, reflexed.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 9–10; filaments c. 6 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary depressed-globose, 4-locular, tomentellous.

Morphology General Habit
Erect shrub 1(–1.5) m tall; stems much branched, ultimate branches 1–3 mm thick, orange-brown, densely stellate-scabrid.
Morphology Leaves
Leaves narrowly ovate, occasionally elliptic, 10–59(–93) mm long, 6–30(–35) mm wide, tip acute to ± rounded, base rounded (rarely truncate), margin singly or doubly finely to coarsely serrate, upper surface grey-green, shortly stellate-hairy, lower surface grey or white, densely shortly and softly stellate-hairy (rarely subscabrid); petiole 6–17 mm, terete, swollen at top, dark brown, stellate-scabrid; stipules falling early, linear, 2 mm long, papery, brown, stellate-hairy.
Morphology Reproductive morphology Inflorescences
Inflorescences subopposite the leaf, cymes (1–)4–5(–8) per node, each cyme with 1–5 flowers; peduncles 2–5 mm long, shortly stellate-hairy; bracts 1–3, linear, 1.5 mm long; pedicels 2–3 mm long, hairy.
Morphology Reproductive morphology Flowers Calyx
Sepals linear-lanceolate, 6–7 mm long, 1.5 mm wide, tip retuse, densely stellate-hairy outside.
Morphology Reproductive morphology Flowers Corolla
Petals elliptic, 4 mm long, 1 mm wide, with rounded tip and clawed base; stamens 8, 4 mm long; ovary globose, densely stellate-hairy.
