الوصف: To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractylodes is a sister group of the Carlina and Atractylis branch. Atractylodes species were distributed among three clades: (1) A. carlinoides (located in the lowest base of the Atractylodes phylogenetic tree), (2) A. macrocephala, and (3) the A. lancea complex, including A. japonica, A. coreana, A. lancea, A. lancea subsp. luotianensis, and A. chinensis. The taxonomic controversy over the classification of species of Atractylodes is mainly concentrated in the A. lancea complex. In base on molecular results, the intraspecific division of Atractylodes lancea is not supported, and A. coreana should be treated as a synonym A. chinensis.

الوصف: Plastid trnL-trnF and nuclear ribosomal ITS sequences were obtained from selected wild-type individuals of Polygonum minus Huds. in Peninsular Malaysia. The 380 bp trnL-trnF sequences of the Polygonum minus accessions were identical. Therefore, the trnL-trnF failed to distinguish between the Polygonum minus accessions. However, the divergence of ITS sequences (650 bp) among the Polygonum minus accessions was 1%, indicating that these accessions could be distinguished by the ITS sequences. A phylogenetic relationship based on the ITS sequences was inferred using neighbor-joining, maximum parsimony and Bayesian inference. All of the tree topologies indicated that Polygonum minus from Peninsular Malaysia is unique and different from the synonymous Persicaria minor (Huds.) Opiz and Polygonum kawagoeanum Makino.
