A new species, Cyclorhiza puana J. Zhou & Z.W. Liu (Apiaceae) from Sichuan Province of China, is described and illustrated here. Morphological comparisons with congeneric species revealed that it is distinguished by its slender habit, sparse annular scars, 4-pinnatisect leaf blade with ultimate segments linear (2-4x0.5-1 mm), subequal rays, oblong fruits with slightly thickened ribs, obconic stylopodium and slightly concave seed face. A molecular analysis based on nuclear ribosomal DNA internal transcribed spacer (ITS) sequences indicated that C. puana is genetically distinct from the other two species of the genus. A distribution map, as well as an updated key, are provided for the species of Cyclorhiza. [ABSTRACT FROM AUTHOR]
