Using DNA sequences from five chloroplast makers (rbcL/trnL-trnF/rps4/rps4-trnS/trnG-trnR), we addressed the phylogenetic affinities of Pellaea connectens, a rare endemic Chinese cheilanthoid fern belonging to Pteridaceae. Our results confirmed that the species was a member of the newly segregated genus Argyrochosma, which was formerly considered as native to America, showing that the treatment of Pellaea connectens by Ching nor Tryon & Lugardon was supported. Moreover, its morphology, distribution, ecology, co-existing species, as well voucher specimens were also presented in this paper.
