Herbaceous liana, climbing over other vegetation and on natural and man- made escarpments; stems conspicuously striate, at least in dried specimens, glabrate or villous to loose-pilose, especially in and near the axils of peduncles, glabrescent. Leaves alternate; blades 6-12 cm long, 2-7 cm wide, ca. 2-3 times longer than wide, lanceolate to ovate-lanceolate, rounded to contracted or sometimes cordate at the base, the margin shallow-serrate or dentate to subentire, the teeth callose-denticulate, the venation pinnate; petiole distinct, 1-2 cm long but uppermost leaves becoming sessile. Inflorescence of 1-2(-3) large heads supported by a conspicuous peduncle 10-30 cm long, arising from axils of the uppermost leaves, sometimes with 1-5 reduced, bractlike leaves arising along the peduncle. Heads campanulate at maturity, red or orange-red to bright orange, large; disc 2-2.5(-3) cm across; principal involucral bracts 30-40, narrowly lanceolate to acicular, gradually acuminate, sometimes red-pink tipped, lightly puberulent or pilose on the outer midrib, 8-12 mm long; calyculate bracts prominent and numerous, irregularly spaced and at most ca. 1/2 as long as the principal involucral bracts, pubescent-pilose on the outside and often along the margins; receptacle gently convex, distinctly shallow-alveolate; ray florets 18-24 in a single whorl, the tube ca. 7 mm long, the ligule 10-15 mm long, 3-4 mm wide in dried specimens; disc florets numerous, 40-60, the corolla 10-12 mm long, the tube and limb not sharply distinguished, the lobes prominent, the sinuses ca. 2 mm deep, the style branches with expanded, papillose, triangular tips. Achene columnar, with ca. 10 prominent ribs, lightly pubescent, 4 mm long, 0.8 mm wide; pappus of white, uniseriate, capillary bristles.
