| We used morphological and molecular characteristics to perform a taxonomic reappraisal of Suaeda australis (Brown) Moquin-Tandon from Korea. Populations of this species are dispersed at the bottoms of sand zones, and usually exhibit a depressed habit. Except for their total heights and leaf lengths, the morphology of these plants does not differ from that of S. maritima. Molecular traits were examined based on ITS and psbB-psbH spacer region sequences. The former region included ITS-1, 5.8S, and ITS-2, which were 629 nucleotide bases long. Pair-wise distances (p-distance) among Korean Suaeda species ranged from 1.12 to 17.84. The psbB-psbH spacer region sequences were 618 nucleotide bases long, and were conserved in the alignment of Korean Suaeda species. In our ML and MrBayesian analysis of ITS sequences aligned with other sequences from GenBank, the plants of Korean Suaeda made three clades: 1) S. japonica; S. australis, and S. maritima; 2) S. mala-cosperma; and 3) S. glauca. However, the psbB-psbH region sequences could not be resolved among S. japonica, S. maritima, and S. australis from Korea. Molecular and vegetative characteristics indicated that the plants now classified as S. australis from Korea should instead be named as S. maritima (L.) Dumont. |
