Duhaldea lachnocephala (Asteraceae: Inuleae: Inulinae), a new species from Yunnan, southwest China.

Duhaldea lachnocephala Huan C. Wang & Feng Yang (Asteraceae: Inuleae) is described and illustrated as a new species. The new species is only known from the Luzhijiang valley, Yunnan Province, southwest China. It is characterized prominently by having dense arachnoid-lanate hairs on stems, leaves and phyllaries, and white marginal florets usually 2-3-seriate. Morphological comparisons with its closest relatives D. nervosa, D. revoluta and D. simonsii are presented. A preliminary conservation assessment of D. lachnocephala is also made under the IUCN criteria. [ABSTRACT FROM AUTHOR]
