Heads radiate, often solitary but up to 3 corymbosely arranged, peduncles axillary or terminating branchlets, long (up to c. 10 cm) with conspicuous narrowly elliptic bracts. Involucre turbinate, bracts c. 12, 9-10 mm long, nerves resinous, calyculus bracts elliptic-lanceolate, almost equalling the involucre, margins often ciliate, appressed at least in the dried state.
