Stems not glaucous, with numerous slightly prominent amber glands throughout; internodes 17–30 mm, shorter than leaves. Leaves sessile, ascending, not glaucous; lamina (main stem) 15–27 × 1.8–2.7 mm, linear, apex rounded, margin revolute, base narrowly cuneate, 1-veined or with 1–2 pairs of lateral branches, with laminar glands pale, rather large, numerous and occasionally one large, subapical, visible only below, marginal glands dense; lamina (axillary and sterile shoots) smaller, narrower, otherwise similar. Inflorescence ∞-flowered, from 5–6 nodes, cylindric, rather lax, 140–190 mm long, with lateral cymules (1)3–5-flowered, without flowering branches below; bracts and bracteoles narrowly oblong to linear, entire. Flowers c. 25 mm in diam., with petals spreading? after flowering; buds globose. Sepals unequal to subequal, basally united, not imbricate, 3–4 × 1–2 mm, narrowly spathulate to oblong, acute or subacute to rounded; veins 3–5; margin distally glandular-denticulate with glands black, ellipsoid to cylindric; laminar glands pale, linear. Petals bright? yellow, not red-tinged, 11–12 × 5–6 mm, c. 4 × sepals, obovate, unguiculate, rounded, distally black-glandular-denticulate; laminar glands pale, few, striiform to punctiform.
