Herbs, annual or perennial. Leaves alternate, pectinate to pinnatisect. Synflorescence of short axillary spikes grouped into a slender, leafy panicle. Capitula rather small, heterogamous, disciform. Involucre ovoid or broadly ovoid; phyllaries in 3 or 4 rows, scarious margins broad. Receptacle narrowly conical, epaleate. Marginal florets usually 3 or 4, female, fertile; corolla narrowly tubular, apex not toothed. Disk florets of two kinds; outer bisexual, inner completely male with reduced ovaries; all central florets with corolla apex 5-lobed. Anther bases obtuse; apical appendage rhomboid-acuminate. Style branches linear. Achenes in a row around base of receptacle, ellipsoid, somewhat compressed or triquetrous, brown, striate. Corona absent.

One species: China, Kazakhstan, Mongolia, Russia.

Molecular data (Watson et al., BMC Evolutionary Biology;; accessed 10 Apr 2011) indicate that Neopallasia is closely related to Seriphidium s.s. and could be included with that genus within a more broadly conceived Artemisia.
