without scales. Female florets exterior, in 1 or 2 series, fertile; corolla broad or conic or wanting. Disc-florets hermaphrodite or often male; corolla regular, tube slender or stout and 2-winged, limb 4-toothed. Anthers obtuse at the base, entire. Stylebranches of the disc-florets truncate or obtuse, sometimes undivided. Achenes compressed, sometimes winged. Pappus wanting.

A genus of 50 or 60 species, scattered widely over the world in both temperate and tropical regions. Several of the New Zealand species are difficult of discrimination, and require further study with more copious suites of specimens.

A. Eucotula. Receptacle flat or convex. Female florets without any corolla. Achenes of the female florets stipitate, in a single row.

B. Strongylosperma. Receptacle flat or convex. Female florets without any corolla. Achenes of the female florets in several rows.
Slender, diffuse, silky. Leaves pinnate or bipinnate. Heads small, 1/10–1/6 in. diam.	2. C. australis.
C. Leptinella. Receptacle convex or conical. Female florets in 1 or several series; corolla always present, usually inflated at the base.
