Abstract:
Anaphalis DC. is the largest genus in Asian Gnaphalieae, and China, containing 54 known species, is one of the largest centers of Anaphalis diversity. In the present study, the achene micro-morphology of 39 Chinese Anaphalis taxa were studied in detail using scanning electron microscopy (SEM). The results showed that the Chinese Anaphalis could be classified into two groups based on achene surface ornamentation viz. reticulate-claviform (Group I) and ligulate protuberant (Group ?). Achene micro-morphological characteristics were useful for the delimitation of interspecific and supraspecific classification within Anaphalis.
