Leaf blade spreading to upswept, oblong-oblanceolate to broadly spatulate, 5-10(-18) cm, leathery, base narrowly cuneate, margins slightly revolute, apex rounded to obtuse-angled; surfaces abaxially glabrate, adaxially glabrous. Inflorescences from axils of new shoots, solitary flowers; peduncle slender, 1-2 cm; bracteole 1, basal, lance-oblong, 5-7 mm, hairy. Flowers nodding to nearly erect, reddish, fetid; perianth (3-)4-merous; sepals elliptic or ovate, ca. 1 cm, abaxially sparsely rusty-hairy; outer petals ascending with spreading pale tips, lanceolate to oblong-lanceolate, 2-2.5 cm, margins slightly revolute, surfaces abaxially glabrate; inner petals ovate-acute or short-acuminate, ca. 1/2 length of outer petals, fleshier than outer petals, base large, saccate, corrugate zone adaxially deep purple; pistils 3-11.
