Leaf blade ascending-spreading, upswept, linear-elliptic to narrowly spatulate or linear-oblanceolate, 5-15(-20) cm, leathery, base broadly to narrowly cuneate or attenuate, margins obscurely to very revolute, apex acute to obtuse, rounded, or rarely notched; surfaces abaxially glabrate, raised-reticulate, adaxially glabrate. Inflorescences from axils along new shoots, solitary flowers; peduncle slender, 2-4 cm, glabrate; bracteoles 1-2, often suprabasal, lance-linear, to 10 mm, hairy. Flowers nodding, fragrant; perianth 3(-6)-merous; sepals elliptic to ovate, 0.5-1 cm, glabrescent; outer petals spreading, white or cream, rarely pink or striped with red or pink, elliptic, oblong, or obovate, 3-8 cm, abaxially glabrate; inner petals erect, maroon to cherry red or white, oblong to lanceolate, to 1/2 length of outer petals, base broad, saccate, corrugate zone adaxially purple, apex spreading; pistils 2-7(-12).
