Morphology Reproductive morphology Flowers
Flowers in dense heads 3–15 cm diameter, surrounded by a conspicuous involucre of bracts; bracts spirally arranged and forming several overlapping series, grading from very small in the outer series to elongate and almost equalling to exceeding the flowers in the inner series, sometimes brightly coloured, glabrous to tomentose; involucral receptacle flat to conical.
Morphology Reproductive morphology Flowers Perianth
Perianth abaxial segment separating completely from the 3 adaxial segments which remain fused for ± their entire length.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary scarcely differentiated from the base of the style, clothed with long stiff brown hairs exceeding itself in length, with a single ovule; style not flattened, glabrous or rarely hairy at the base, terminated by a linear pollen-presenter.
