Hybridization and reticulate evolution in Diphasiastrum (flat-branched clubmosses) in Taiwan and adjacent countries

Hybridization in the species groups around Diphasiastrum multispicatum and D. veitchii was investigated in Vietnam and Taiwan, including available herbarium specimens from all over southeast Asia. The accessions were analyzed with flow cytometry, Sanger sequencing and multiplexed inter-simple sequence repeat genotyping by sequencing. We detected two cases of hybridization.
