3. Saussurea sect. Gymnocline Franchet, J. Bot. (Morot). 2: 311. 1888.

无茎风毛菊组 wu jing feng mao ju zu

Herbs, stemless or substemless but sometimes with branched woody caudex and densely caespitose or forming dense cushions. Leaf blade margin entire, serrate, dentate, or sinuate. Capitula usually solitary in center of leaf rosette, large or medium-sized, sometimes several in a clustered synflorescence, sessile or shortly pedunculate. Receptacle with subulate, sometimes very short bristles or naked. Corolla glabrous or sometimes gland-dotted. Anther tails lacerate or lanate. Achene glabrous or glandular, without an apical crown but sometimes with a crenulate rim. Pappus usually in 2 rows; outer bristles scabrid or plumose, rarely very few or lacking.

Twenty species: Bhutan, China, NE and NW India, Japan, Kashmir, Nepal, Tajikistan; 17 species (13 endemic) in China.

Saussurea sect. Acaules C. B. Clarke (Compos. Ind. 220. 1876) was lectotypified by Kitamura (Acta Phytotax. Geobot. 24: 22. 1969) with S. stoliczkae (= S. andryaloides), a species now included in S. sect. Strictae. Lipschitz (Rod Saussurea, 106. 1979) explicitly excluded this lectotype from his S. sect. Acaules and thereby created an illegitimate later homonym (Vienna Code, Art. 48.1). The lectotype of S. sect. Depressae C. B. Clarke (loc. cit.: 221; chosen by Lipschitz, loc. cit.: 96-97) is S. andersonii, now also included in S. sect. Strictae. Saussurea sect. Depressae has often been regarded as highly artificial (Lipschitz, loc. cit.: 97). Moreover, its key character is not even very useful for grouping of species. Naked receptacles can be observed in most other sections as well and may only be used for keying out certain groups within a section. For this reason, S. sect. Depressae is merged here with S. sect. Acaules. The correct name for this section is S. sect. Gymnocline, typified by S. ciliaris.
