Podolepis is an Australian genus of wiry herbs producing commonly yellow flowerheads with involucres bearing membranous bracts (Black & Robertson 1965).

Characters (from Black & Robertson 1965): Rather rigid wiry herbs with alternate entire leaves; flowerheads terminal, usually solitary; flowers usually all yellow. Involucre ovoid to hemispherical, the bracts unequal in several rows, with hyaline non-radiating laminae, at least the outer ones sessile; receptacle flat, naked; outer flower female, longer than involucre and sometimes forming conspicuous ray, limb rather deeply cut into three or four narrow lobes or extended in a short two- to four-toothed ligule; inner flowers always more numerous, bisexual, tubular, usually five-lobed; anthers tailed; style-branches truncate; achenes terete; pappus of capillary bristles shorter than corolla.
