Herbs, perennial, 10-60 cm tall. Leaves in basal rosette; petiole 3-9 cm, distal part winged, proximal part wingless, rarely nearly wingless; leaf blade ovate or ovate-lanceolate, 2-7 × 2-5 cm, papery, palmate-pinnate veined, both surfaces sparsely villous, base attenuate, margin slightly repand, callose-denticulate, apex acute or obtuse. Capitula subsessile or shortly pedunculate, commonly 2 or 3 clustered, arranged in spikes, (1-)3-flowered; involucre cylindric, 2-3 mm in diam.; phyllaries ca. 5-seriate, papery, abaxially glabrous or apically pilose, outer phyllaries ovate, 1.5-2.5 mm, inner lanceolate, ca. 1.2 cm. Florets bisexual, chasmogamous and cleistogamous (in same plant or at different seasons). Chasmogamous floret corollas tubular, 5.5-9 mm, deeply 5-lobed, anther appendages rounded. Achenes terete, ca. 3 mm, ribbed, densely pilose; pappus absent. Fl. Dec-Apr. Cleistogamous floret corollas closed, tubular, minutely 4-lobed, ca. 4 mm, hidden in pappus.

Ainsliaea tonkinensis, a rheophyte distributed in Vietnam, is sometimes treated as a synonym of A. reflexa (see Freire, Ann. Missouri Bot. Gard. 94: 149. 2007). Further studies are necessary to confirm whether or not they are conspecific.
