| 中文摘要 | a new species of saussurea, s. erecta s. w liu, j. t pan a j. q. liu sp. nov., is described from tibet. it resembles s. kingii but may be distinguished by having distinct stems and glabrous achenes. saussurea kingii was placed in sect. pseudoeriocoryne of subgen. eriocoryne; this section was circumscribed by acaulescence and an inflorescence with congested capitula surrounded by a rosette of leaves. the discovery of s. erecta with distinct stems, cauline leaves and corymbose capitula blurred the delimitation of sect. pseudoeriocoryne and suggested that the section may be polyphyletic. both the close relationship and the significant difference between s. erecta and s. kingii were confirmed by analyses of nrdna its sequences. the resulting phylogenies based on its data further suggest that saussurea sect. pseudoeriocoryne, as traditionally defined, does not constitute a monophyletic group. the rapid radiation and speciation of saussurea in the qinghai-tibetan plateau, as inferred from its phylogeny, are discussed.
