Involucre campanulate or conical; phyllaries in 3 or 4 rows, herbaceous or rigidly herbaceous, scarious margins white or brown. Receptacle flat to convex, epaleate.

Hippolytia dolichophylla (Kitamura) K. Bremer & Humphries (Bull. Nat. Hist. Mus. London, Bot. 23: 106. 1993; Chrysanthemum dolichophyllum Kitamura, Acta Phytotax. Geobot. 23: 73. 1968, based on Tanacetum longifolium Wallich ex Candolle, Prodr. 6: 130. 1838, not Thunberg (1800); C. longifolium K. H. Rechinger (1955), not Sessé & Mociño (1894); T. dolichophyllum (Kitamura) Kitamura; T. himachalense Aswal & Mehrotra, nom. illeg. superfl.) was recorded from Sichuan in Annot. Checkl. Fl. Pl. Nepal (69. 2000, as T. dolichophyllum), disjunct from the main area of distribution in the Himalaya between Kashmir and Nepal (see http://www.efloras.org/florataxon.aspx?flora_id=110&taxon_id=242425863; accessed 8 Apr 2011). No specimen has been seen by the present authors. This species would key out as H. herderi, but it differs from that species and all others in Hippolytia by having leaves 12-25 cm.

Nineteen species: C Asia, China, Himalaya, Mongolia; 11 species (six endemic) in China.
