Saussurea subsect. Rosulascentes Kitamura, Acta Phytotax. Geobot. 24: 22. 1969.

Herbs, perennial, rhizomatous, with well-developed, simple or branched flowering stems. Basal and lower stem leaves rosulate or subrosulate, present at anthesis. Middle and upper stem leaves few, much reduced. Capitula solitary or several, sometimes supported by uppermost stem leaves. Involucre campanulate, ovoid, cylindric, funnel-shaped, turbinate, or subglobose. Phyllaries imbricate, margin entire, apex obtuse or acuminate. Receptacle with bristles. Anther tails ciliate or lacerate. Achene usually ribbed, glabrous, sometimes with a small crown. Pappus usually in 2 rows; outer bristles scabrid, rarely lacking.

About 17 species: China, Korea, Russia (Far East, Siberia); nine species (eight endemic) in China.

Saussurea sect. Rosulascentes is rather ill-defined as there are many species with few and reduced stem leaves, which have been placed in other sections, and some of the following species can have a number of stem leaves as well. Saussurea alatipes and S. huashanensis are very similar to S. fargesii, so they have been placed in this section. However, these three species may also be placed in S. sect. Saussurea.
