Leaves: basal withering by flowering, proximalmost cauline petiolate or sessile, usually withering by flowering, proximal usually largest, not 3-nerved (except S. drummondii), usually with pronounced lateral nerves along entire midnerve. Heads in thyrsiform-paniculiform, open to congested, cone-shaped secund arrays, proximal branches arching, secund, often proximalmost elongate and array repeated distally. Phyllaries not striate, eglandular. Pappi bristles usually in 2, rarely in 3 series (shorter, outer setiform scales rarely present, inner weakly, if at all, clavate, moderately so in S. odora).
Distribution
North America.
Discussion
Species 7 (7 in the flora).
Selected References
None.
