Shoot leaves subimbricate, aggregated into a rosette; leaf blade subobpandurate-oblong to narrowly ovate or narrowly obovate, abaxially convex, adaxially concave, 3-5.6 × 1-2.1 mm, leathery, both surfaces glabrous, chalk glands 3, margin ± setose-ciliate, apex ± recurved, acute or mucronate. Cauline leaves 4-8, spatulate- or oblanceolate-oblong to oblong, abaxially convex, adaxially subconcave, 3.3-5.3 × 1-1.5 mm, leathery, abaxially ± glandular hairy, adaxially glabrous, chalk glands 1(-3), margin glandular ciliate, apex ± recurved, obtuse or acute. Flower solitary; pedicel initially nearly absent, then elongated, to 2 mm, glandular hairy; bracts oblong to spatulate-oblong, 3.3-4 × ca. 1 mm, leathery, glandular hairy abaxially proximally and at margin, glabrous adaxially, chalk gland 1, apex acute, glabrous.
