Description:  "Plants scandent, with slender stems, pith solid; stems, undersides of leaves, and peduncles densely silvery sericeous with long-armed T-shaped hairs. Leaves alternate, short-petiolate; blade oblong to obovate, base obtuse, margins entire to remotely denticulate, apex rounded to apiculate, upper surface green, nearly glabrous, with few scattered hairs, undersurfaces densely sericeous with slender, appressed T-shaped hairs, secondary veins pinnate, 4-6, irregularly arching toward tip. Inflorescences terminal on branches, narrowly pyramidal with usually short, lateral corymbiform branches and branchlets, mature branches usually deflected at nodes; heads in small rather dense clusters; involucral bracts imbricated in ca. 5 series, broadly obtuse to rounded at tip, inner bracts tardily deciduous; receptacle glabrous. Florets ca. 5; corollas white or pale purple in bud and becoming white, ca. 6 mm long, texture of corolla wall thin, funnelform from ca. 1.5 mm above base, without hairs, with scattered glands; anther thecae tailed with minimal basal fringe, apical appendage narrowly oblong; style base broadened with annulus of sclerified cells; upper shaft and branches of style with blunt sweeping hairs. Achenes 5-sided, rarely with extra angle, without hairs, with glandular dots, with numerous idioblasts on surface, with scattered small rhombic or short oblong raphids in wall; carpopodium narrowly stopper-shaped, nearly cylindrical, longer than wide; pappus of numerous slender bristles, narrow near base, broadened distally, somewhat fragile, with few short bristles interspersed"  (Robinson & Skvarla, 2010; p. 270).
