Dichrocephala integrifolia is close relative of Dichrocephala benthamii, but differs from the latter in its pistillate florets slender, linear (vs. ovate or urceolate), leaves lyrate, pinnatilobate basally, base gradually attenuate into winged petiole (vs. pinnatilobate, sessile, base expanded auriculate-amplexicaul).

Herbs annual. Stems erect, 12-50 cm tall, robust, rarely slender, simple or branched from base, branches ascending, stems and branches white villous or pubescent. Leaves ovate, elliptic, or lanceolate, sparsely puberulent on both surfaces, petioles 1-3.5 cm, winged, margin doubly coarsely serrate or incised, middle cauline leaves 3-12 cm long, 2-4.5 cm wide, lyrate pinnatilobate, terminal lobe large, ca. 4.5 cm wide, lateral lobes 1- or 2-paired, upper or lower leaves gradually smaller, basal leaves often simple. Capitula small, globose, 3-5 mm in diameter, numerous in terminal corymbs or corymbose-panicles; peduncles slender, to 3 cm. Phyllaries 1- or 2-seriate, membranous, oblong or oblong-lanceolate, unequal, ca. 1 mm. Marginal florets many-seriate, purple, corolla slender, linear, ca. 0.5 mm, apically usually 2-denticulate; central bisexual florets few, ca. 0.5 mm, with short tube and campanulate limb, 4- or 5-denticulate. Cypselas compressed, obovate, glabrous. Pappus absent, or of bisexual florets with 1-2 bristles.
