tahinia

Tahinia is a genus of flowering plants in the family Asteraceae. It is described in botanical literature and currently comprises three species: Tahinia alba, Tahinia rubra, and Tahinia caerulea.

Morphology: Species in Tahinia are compact, perennial herbs or small shrubs typically 15–70 cm tall. They have alternate, simple leaves that are smooth or sparsely hairy. The inflorescence is a capitulum typical of Asteraceae, with pale yellow or white ray florets and yellow to orange disc florets; the fruit is a single-seeded cypsela.

Distribution and habitat: Tahinia is native to arid and semi-arid regions around the southern Mediterranean, including coastal dunes and rocky hillsides. It prefers well-drained soils and full sun, and tolerates drought. Populations are scattered and often restricted to specific microhabitats; some areas may host endangered populations.

Taxonomy and etymology: Tahinia belongs to the tribe Heliantheae within Asteraceae. The name Tahinia is derived from a toponym used at the type locality.

Uses and conservation: Tahinia species are sometimes grown as ornamentals in drought-tolerant landscapes and for stabilizing sandy substrates. Conservation concerns arise from habitat loss and climate change; assessments vary by species and region.
