Tolpis is a genus of annual and perennial flowering plants in the family Asteraceae (the daisy family), placed in the tribe Cichorieae — the chicory tribe that also includes dandelions, hawkweeds, and chicory. The genus comprises roughly 20–25 species of herbaceous plants bearing characteristic yellow, ligulate (strap-shaped) flower heads typical of the tribe.

The genus is distributed across Africa, southern Europe, the Middle East, and the Macaronesian archipelagos. A notable concentration of endemic species occurs in the Canary Islands, where the genus has diversified into a variety of ecological niches across the islands' altitudinal gradients. Other species occur across the broader Mediterranean basin, from the Azores in the west to the Arabian Peninsula in the east, and into sub-Saharan Africa as far south as the Cape.

Well-known members include Tolpis barbata, a slender annual of dry, disturbed ground across the Iberian Peninsula and North Africa; Tolpis umbellata, widespread through the Mediterranean to Palestine; and Tolpis capensis, which ranges from Ethiopia to South Africa and Madagascar. The genus was named and circumscribed by the French botanist Georges Louis Marie Dumont de Courset in the early nineteenth century and remains accepted within current Asteraceae classification.

Distribution

Tolpis is native to Africa, southern Europe, the Middle East, and Macaronesia (the Canary Islands, Azores, Madeira, and Cape Verde). Many species are endemic to the Canary Islands, while others range broadly across the Mediterranean basin or extend into sub-Saharan Africa as far as the Cape Province and Madagascar.

Taxonomy Notes

Tolpis belongs to the tribe Cichorieae within the family Asteraceae, the large composite or daisy family. Cichorieae is characterised by all-ligulate flower heads (no disc florets), and includes familiar genera such as Taraxacum (dandelions), Hieracium (hawkweeds), and Cichorium (chicory). The genus is accepted in GBIF under the order Asterales.
