Stems densely pubescent with yellow-ferruginous or ferruginous, sessile and shot stipitate porrect stellae, the stipes to 0.13 mm, the stellae tardily deciduous, 0.2–0.6 mm broad, with 6–8 rays, the midpoint erect to flexed at the base ±90°, ±equal to the rays; bark reddish brown, a transparent sloughing layer absent on young stems; stems unarmed or with scattered prickles, the prickles to 5.7 × 2.3 mm, broad based, narrowly triangular, straight, red-orange.
Sympodia difoliate, geminate or not.
Leaves simple, geminate or borne individually, the blades of major leaves 5.1–15.4 × 2.3–6.8 cm, 1.5–2.4 times as long as wide, ovate to oblong, chartaceous to subcoriaceous, the minor leaves 1/2 as large to ±equal to the major leaves, both major and minor leaves densely pubescent above with sessile and short stipitate porrect stellae and minute glandular hairs when young, glabrous or sparsely pubescent when mature, the stellae 0.3–0.6 mm in diameter, with 4–8 rays, the stipes to 0.01 mm long, the midpoint of the stellae erect, slightly shorter than the rays, the glandular hairs to 0.06 mm long, densely pubescent below with sessile and short stipitate porrect stellae and minute glandular hairs when young, moderately to densely pubescent when mature, the stellae 0.3–0.6 mm in diameter, with 4–8 rays, the stipes to 0.08 mm long, the midpoint of the stellae ±erect, slightly shorter than the rays, the glandular hairs to 0.4 mm long; blade unarmed or with few to many straight prickles on the primary vein or on the primary and secondary veins abaxially and adaxially, with 5–9 veins on either side of the midvein, the midvein raised abaxially, distinct adaxially, the lateral veins craspedodromous or semicraspedodromous, raised abaxially, distinct adaxially; blade base rounded to cuneate, aequilateral or oblique; margin sinuate or lobed, the apices of the lobes rounded; apex subacute to acute; petiole 1.4–4.7 mm long, 0.9–1.5 mm in diameter, channeled above, densely pubescent, unarmed or with scattered straight prickles.
Inflorescence 1.1–7.7 cm in flower and fruit, appearing lateral, extra-axillary, emerging from the upper 1/3 of the internode, unbranched or branching to 4 times, with up to ca. 90 flowers, all apparently fertile or potentially so, the axes densely pubescent, the hairs sessile porrect-stellate, unarmed or occasionally with scattered prickles; peduncle in flower 6.5–16.0 mm long, 0.6–1.0 mm in diameter, the branches to 4.3 cm long, to 0.6 mm in diameter, in fruit 2.6–3.7 cm long, 0.6–2.2 mm in diameter, the branches with fruits and flowers to 6.3 cm long, to 1.4 mm in diameter; pedicels 7.0–1.4 cm long, 0.4–0.6 mm in diameter at the base, 0.9–1.3 mm in diameter below the calyx, straight, bent to ±90° below the calyx, increasing in diameter in the distal immediately below the calyx, densely pubescent, the bases congested to somewhat well spaced to 2.6 mm apart in flower, 1.0–2.1 cm long, 0.6–0.9 mm in diameter at the base, 1.5–3.1 mm in diameter below the calyx, straight, bent to ±90° below the calyx, gradually increasing in diameter in the distal 1/3–1/2, moderately to densely pubescent, the bases well spaced to 5.2 mm apart, in fruit, rigid, in two rows, articulate at the base. Buds globose, the calyx densely stellate-pubescent, the corolla densely stellate-pubescent, the surface of the corolla of the mature bud ridged.
Flowers heterostylous, 5-merous. Calyx 2.2–3.1 mm long, unarmed or occasionally with several, straight prickles, appearing nearly truncate with deltoid lobe tips, the tube 1.4–1.5 mm long, the lobe tips 0.8–1.5 × 0.6–1.3 mm, the intersepalar tissue opaque when dry; splitting in the sinuses at anthesis and then the lobes dentate, 1.9–2.6 × 1.2–1.9 mm at anthesis, densely pubescent abaxially, glabrous or sparsely pubescent adaxially, the calyx lobes in fruit 2.6–4.8 × 1.9–3.2 mm, moderately to densely pubescent, appressed or reflexed,. Corolla 1.4–1.9 cm in diameter, stellate with poorly developed, glabrous interpetalar tissue, white or white with purple veins, the lobes 5.2–6.3 × 3.2–6.2 mm, triangular to deltate, the midrib 6.9–9.2 × 3.1–4.0 mm, lanceolate, densely pubescent abaxially, glabrous at the base, scattered pubescence towards the apex adaxially, spread wide at anthesis.
