Chamaescilla is a small genus of perennial herbs in the family Asphodelaceae (order Asparagales), placed within the subfamily Hemerocallidoideae. Native to Australia, these plants grow from tuberous roots and produce grass-like basal leaves. The flowers are six-petalled, each petal bearing three nerves, with six stamens. After flowering, they form seed capsules that release black, glossy seeds. The genus comprises four accepted species, the most widespread being Chamaescilla corymbosa (commonly called Blue Stars, Blue Squill, or Mudrurt), which ranges across Western Australia, South Australia, Victoria, and Tasmania. The remaining three species — C. gibsonii, C. maculata, and C. spiralis — are endemic to Western Australia; C. spiralis is distinguished by its characteristically curled basal leaves.
Distribution
All four accepted species of Chamaescilla are Australian. Chamaescilla corymbosa is the most widespread, occurring in Western Australia, South Australia, Victoria, and Tasmania. The remaining three species — C. gibsonii, C. maculata, and C. spiralis — are restricted to Western Australia.
Taxonomy
Chamaescilla belongs to the subfamily Hemerocallidoideae within the family Asphodelaceae, order Asparagales. The genus was authored by Ferdinand von Mueller and George Bentham as "F.Muell. ex Benth." One species formerly included, Chamaescilla dyeri, has been reclassified as Arthropodium dyeri.
