<p><strong><em>Thalictrum nanhuaense</em> (Ranunculaceae), a new species from central Yunnan, China</strong></p>

Thalictrum nanhuaense (Ranunculaceae), a new species from Nanhua in central Yunnan, China, is here illustrated and described. The new species is similar to T. fargesii in habit and having larger sepals up to 4 mm long and persistent at anthesis and straight styles, but differs by its succulent and tuberose (vs. fibrous and slender) roots, filiform (vs. clavate) filaments, point-like (vs. oblong and narrowly winged) stigmas, and subulate-terete (vs. lunate-fusiform) achenes.
