Characteristics

Suffrutex with several stems from a stout, woody rootstock; stems usually less than 30 cm tall, simple to laxly branched in second year, fairly laxly stellate-pubescent and with minute glands or minute gland-tipped hairs intermingled. Stipules linear-filiform or linear-lanceolate, about 5 mm long and less than, or up to 1 mm broad, sparsely stellate-pubescent. Leaves shortly petiolate; blade elliptic, elliptic-oblong, ovate-elliptic or lanceolate, 2-6.5 cm long, 0.3-2.2 cm broad, crenate-dentate, crenations sometimes small and distant, concolorous, upper surface with impressed veins, fairly densely to sparsely pubescent with simple or 2-or more-rayed, bulbous-based hairs, lower surface with prominent veins and sparsely stellate-pubescent with hairs usually shorter than on upper surface; petiole 1.5-6 mm long. Inflorescence axillary and terminal, flowers usually solitary on long peduncles up to 5 cm long; pedicels short, about 3 mm long; bracts linear-filiform, 1-2 on peduncle and 2 at base of pedicel, about 1-3 mm long. Calyx 8-14 mm long, lobed to midway or just beyond, stellate-pubescent without and usually intermingled with minute gland-tipped hairs. Petals 1.1-1.9 cm long, “crimson”, “red-orange”, “orange”, “red”, upper third suborbicular, slightly broader than long, narrowing into a claw with infolded margins. Stamens united at base to a long stipe, free part of filaments hyaline, narrowly obovate, broader at apex, about 1 cm long, obscurely stellate on shoulders; anthers about 1 cm long, ciliate with basal portion overlapping dilated filaments. Ovary stipitate, 5-angled, densely stellate-pubescent, stellate pubescence on keel of angles shortly stalked; styles 6 mm long, minutely and sparsely hairy with short patent hairs. Capsule oblong-orbicular in outline, deeply 5-angled, roughly pubescent with short-rayed, stellate hairs and fringed on keel of angles with crowded, tentacle-like processes up to 7 mm long (developed from stalks of stellate hairs), calyx subpersistent at base, ultimately reflexed and withered to expose a 4 mm long stipe; seeds reniform-orbicular, plicate.
