“…The monophyly of the genus Scutellaria was confirmed in the present study ( Fig. 3 ), as reported by previous molecular phylogenetic studies ( Li et al, 2012 ; Li et al, 2016 ; Xiang et al, 2013 ; Chen et al, 2014 ; Chen et al, 2016 ). However, the subgenus Scutellaria defined by Paton (1990a) is non-monophyletic with members of the subgenus scattered in various clades.…”

Scutellaria wuana, a new species discovered from a xeric valley in Muli County of Sichuan Province in southwest China, is described and illustrated. Morphologically, the new species shares similarities with S. mairei, but can be readily distinguished by a suite of morphological characters including a white-pubescent erect stem, conspicuous leaf petioles, and a yellow corolla with a trapeziform lower-middle lip lobe. The habitat and distribution of S. wuana are also distinctive. The position of the new species within Scutellaria is examined in a phylogenetic context using the nuclear ribosomal internal and external transcribed spacers. Additionally, we examine leaf epidermal and pollen grain micromorphology of the new species and putative relatives.

“…-States for nine morphological and biogeographical characters repre senting vegetative morphology (habit, leaf shape, trichomes), reproductive morphology (corolla tube, calyx, nutlet), and bio geography (distribution pattern) were reconstructed using Mes quite v.2.7.1 (Maddison & Maddison, 2009). All morphological characters were scored based on examination of herbarium material (CDBI, E, K, KUN, MO, PE), as well as on our previ ous experience working with this group (Xiang & al., , 2010(Xiang & al., , 2012b(Xiang & al., , 2013. Character optimization was performed on the Bayesian consensus tree using a parsimony model with the unordered states assumption as implemented in Mesquite.…”

“…Wu & Li (1965, 1977 recognized two morphological characters, habit and calyx shape, as being most useful for determining relationships within Chelonopsis, especially at the subgeneric level. Several authors have also noted that particu lar characters are taxonomically significant at the sectional or series level (Weckerle & al., 2009;Xiang & al., 2010Xiang & al., , 2012bXiang & al., , 2013. Here, we tentatively optimized nine selected morpho logical characters on the majorityrule consensus tree from the combined datasets (Fig.…”

The recently established tribe Gomphostemmateae (Lamiaceae) consists of Gomphostemma, Bostrychanthera and Chelonopsis, but relationships within and between these genera have not been well studied. Only six of the approximately 46 species of Gomphostemmateae have been included in any previous phylogenetic analysis. In the present study, we used DNA sequences of two nuclear regions (ITS, ETS) and five plastid loci (psbA–trnH, rps16, trnL intron, trnL–trnF spacer, trnS–trnG) to reconstruct the phylogeny of the East Asian genus Chelonopsis for the first time. The molecular results indicate that the tribe Gomphostemmateae is monophyletic; Bostrychanthera is embedded in Chelonopsis; and Chelonopsis comprises two clades, one encompassing the taxa of Chelonopsis subg. Chelonopsis and the genus Bostrychanthera and the other consisting of Chelonopsis subg. Aequidens. This split is supported by several morphological characters. These results, which are further strengthened by morphological and cytological data, indicate that Bostrychanthera should be transferred to Chelonopsis. In addition, our results show that within C. subg. Aequidens, sect. Aequidens and sect. Microphyllum are monophyletic. Furthermore, two major clades are concordant with the Sino–Japanese and Sino–Himalayan distribution patterns.

A new species, Lysimachia septemfida (Primulaceae), from Yunnan (Southwest China) is described and illustrated. The new species exhibits several unusual characters in Lysimachia including lack of a corolla, 7-merous flowers, leaves in whorls of 3 and distinct multicellular nodiferous hairs, which make it readily distinguishable from all other species in this genus. The diagnostic differences between this new species and its suppositive allies are given. In addition, the systematic placement of this new species is also discussed based on an ITS molecular tree.
