  • Evax Gaertn.
  • Gifola Cass.
  • Logfia Cass.
  • Oglifa Cass.

    Tomentose annual herbs of varying habit with alternate lanceolate to spathulate leaves. Capitula small, usually in dense glomerules, disciform. Glomerules numerous, often overtopped by lateral branches. Involucre ovate to pyramidate; phyllaries numerous, sometimes distinctly 5-seriate, at fruiting time convergent, divergent or even stellately spreading. Florets yellowish, very small, female florets filiform, the outer ones always without pappus and in the axils of the outer phylla¬ries (called receptacular scales by some authors), their cypselas sometimes included in the phyllaries. In the centre female florets with pappus and few (often 4-5) bisexual florets or only bisexual florets with or without pappus. Bisexual florets fertile or sterile. Cypselas very small, papillose, sometimes heteromorphous; pappus capillaceous, slightly scabrous.

    A genus of c. 40 species mainly in the Mediterranean region and Western Asia, 6 species in Pakistan. Several species are very similar in habit and may be easily confused without close inspection.
