6. Saussurea sect. Strictae C. B. Clarke, Compos. Ind. 221. 1876.

羽裂风毛菊组 yu lie feng mao ju zu

Aplotaxis Candolle; Cyathidium Lindley ex Royle; Eriostemon Lessing (1832), not Smith (1798).

Herbs, perennial, stemless, substemless, or with developed leafy or scapiform stems. Leaves usually pinnately dentate, pinnately lobed, or pinnatisect, rarely undivided. Capitula usually relatively large, solitary, sometimes 2 or 3 in center of leaf rosette or terminal on stem, rarely numerous in a clustered corymbiform synflorescence. Phyllaries in many rows, imbricate, often subequal in length. Receptacle usually with subulate bristles, rarely naked. Anther tails usually lanate or villous. Achene ribbed, smooth or transversely rugose, glabrous. Pappus usually in 2 rows, white, straw-colored, or brown; outer bristles short, deciduous, scabrid, rarely plumose or barbellate, rarely lacking; inner bristles long, plumose.

About 44 species: Bhutan, China, NE and NW India, Kashmir, Nepal; 36 species (27 endemic) in China.

Saussurea sect. Strictae occurs mainly on the Qinghai-Xizang Plateau and in the Hengduan Shan region.

Saussurea sect. Cyathidium, the name used by Lipschitz (Rod Saussurea, 154. 1979) for both stemless and cauliferous species with predominantly pinnately divided and often dandelion-like leaves, is not the earliest legitimate name for this taxon at sectional rank. Saussurea taraxacifolia, the type species of the genus Cyathidium, was included in S. sect. Strictae by C. B. Clarke (loc. cit.) and chosen as a lectotype of that section by Lipschitz (loc. cit.: 155). Saussurea andersonii, the lectotype species of S. sect. Depressae, is considered here to be a member of S. sect. Strictae as well. Saussurea sect. Acaules, lectotypified by Kitamura (Acta Phytotax. Geobot. 24: 22. 1969) with S. stoliczkae (= S. andryaloides), is also a synonym of this section. See also the discussion under S. sect. Gymnocline.
