Paraphlomis jinggangshanensis (Lamiaceae), a new species from Jiangxi, China

Abstract

Paraphlomis jinggangshanensis (Lamiaceae), a new species from Jiangxi Province, China, is described and illustrated. The new species is morphologically similar to P. intermedia, but can be easily distinguished from the latter by its cordate leaf base (vs. cuneate, decurrent), stem and calyx tube with glandular hairs (vs. short pubescent), and glabrous anthers (vs. ciliate anthers). A phylogenetic analysis, based on ITS regions, suggests that P. jinggangshanensis represents a separate branch in Paraphlomis and is closely related to Clade II. It is currently known only from Jinggangshan National Natural Reserve. Because of its limited distribution and small population size, the species was assessed as Near Threatened (NT) according to the IUCN Red List Categories and Criteria.

“…The combined nuclear data set was 1211 bp (773 bp for ITS, 438 bp for ETS) in length, including 347 variable sites (165 for ITS, 182 for ETS) and 200 parsimony-informative characters (87 for ITS, 113 for ETS). The resulting phylogenetic tree of Paraphlomis in this study was similar to that in previous studies (Chen et al 2021;Zhao et al 2022). The two accessions of P. baiwanensis grouped together (Fig.…”

“…The nuclear ribosomal internal and external transcribed spacers (ITS and ETS) were used for reconstructing the phylogeny of the suspected new species and related taxa based on previous study (Chen et al 2021;Zhao et al 2022).…”

Paraphlomis yingdeensis (Lamiaceae), a new species from Guangdong (China)

“…Field observations and collections of the new species were carried out from May to August in 2022 in Boluo Town of Yingde City in northern Guangdong Province, China. Morphological comparisons of the putative new species with other Paraphlomis species were conducted firstly by consulting relevant taxonomic literature, included “Flora of China” ( Li and Hedge 1994 ), “Flora of Guangdong” ( Luo 1995 ) and other recently described species and infraspecies of Paraphlomis ( Yan and Fang 2009 ; Ding et al 2019 ; Zhang et al 2020 ; Chen et al 2021 , 2022a , b , c ; Zhao et al 2022 ). We also carried out a check of herbarium specimens deposited in LBG, AU, IBK, FJFC, PE, ANUB, KUN, FJSI and SYS (herbarium acronyms following Thiers 2022 ).…”
