Abstract
Based on field investigations, morphological and molecular systematic studies, a new species, Pternopetalum shunhuangensis (Apiaceae) from Hunan Province, China is described. Diagnostic morphological characters, full description and a detailed illustration are provided. The differences between P. shunhuangensis and morphologically similar species P. tanakae are presented and discussed. Since no population assessment of this species in its whole distribution area is made, it is best to assign a conservation status of ‘Data Deficient’ (DD) for this species.
Key words: Apiaceae, China, new species, Pternopetalum

Diagnosis. Pternopetalum shunhuangensis differs from P. tanakae (Franch. & Sav.)

A more detailed comparison between the two species is presented in Table 1.
