Herbs, perennial, ca. 50 cm tall (lower part not seen). Stems slender above middle, branched, puberulent, upper part white velutinous, densely or loosely leafy in upper part. Leaves abaxially gray-green, adaxially somewhat shiny, (lower leaves not seen); middle leaves sessile or shortly petiolate (petiole ca. 1.5 mm); blade lanceolate, 4-7.5 × 0.9-1.6 cm, abaxially densely velutinous, adaxially glabrous, villosulous at base and on veins, thin, base slightly rounded or subcuneate, margin slightly revolute, entire, scabrous, triplinerved, veins ± prominent abaxially, lateral veins 6 or 7 pairs, apex acuminate, sometimes falcate, mucronate. Capitula 2 or 3 at ends of branches, in ± corymbiform synflorescences; shortly pedunculate. Involucres campanulate, 4-5 mm; phyllaries 4- or 5-seriate, unequal; outer phyllaries ovate, ca. 1.5 mm, abaxially puberulent; inner phyllaries oblong, ca. 4 mm, margin narrowly scarious, apex rounded to obtuse, thick. Ray florets not seen; disk florets yellow, 3.4-3.8 mm, tube 1.2-1.3 mm, limb narrowly campanulate, lobes lanceolate, 1.1-1.2 mm, apically glandular and villous. Achenes brown, narrowly oblong, slightly compressed, ca. 2.9 mm, sparsely strigose, moderately so distally, pale 5- or 6-ribbed. Pappus reddish brown, 2-seriate; inner series ca. 3 mm, acute; innermost series 3.3-3.6 mm, clavate. Fl. Jul.

Ray florets were not observed by us on the available specimens of Aster velutinosus; the capitula on the type specimen are too immature. On the fruiting specimen, however, there is no sign of ray florets, including on a head that was not fully opened; only disk florets were seen there.
