| Abstract: | Batrachospermum arcuatum Kylin is typically dioecious, although some monoecious specimens have been collected from four locations in North China. In this study, B. arcuatum populations, including monoecious and dioecious thalli, were collected from seven stream segments. The nuclear DNA internal transcribed spacer (ITS) region was sequenced for the seven populations, and a phylogenetic tree was constructed using Bayesian inference to assess intraspecific relationships. A haplotype network was also created. The ITS region in B. arcuatum from North China comprised 822–853 bp, with 10 haplotypes detected from the seven locations. The results of this study support the inclusion of monoecious individuals in the species B. arcuatum. |
