Phyllaries 30–40, distant, 2 or 3–seriate, equal or subequal, lanceolate, acute to acuminate, markedly hardened, often with scarious margins. Receptacle conical, glabrous or paleaceous. Florets 20–125. Corolla white, blue, or lavender, funnel form or with distinct basal tube; lobes 5, as long as wide, sparsely papillose and sometimes hispidulous on outer surface, papillose on inner surface; antheropodium cylindric; style base not enlarged, glabrous, style branches linear, usually strongly and densely papillose.
