Trichosporeae is the largest and most taxonomically difficult tribe of Gesneriaceae due to its diverse morphology. Previous studies have not clarified phylogenetic relationships within this on several DNA markers, including generic subtribes. Recently, plastid phylogenomics been successfully employed resolve at different taxonomic levels. In study, were used explore Trichosporeae. Eleven plastomes Hemiboea newly reported. Comparative analyses, phylogeny morphological character evolution...

With more than 160 described species, Primulina is one of the most characteristic plant groups Sino-Vietnamese limestone flora. In our continous botanical inventory flora South China, we collected three new species not identifiable to known species. Molecular phylogenetic analyses based on nuclear ITS and chloroplast trnL-F trnH-psbA sequences strongly support placement in Primulina. addition morphological differences, DNA all these show substantial divergencies, sustaining recognition Based...

Abstract Adaptive radiation is usually triggered by great in situ or ex environmental changes. How an adaptive occurs on lands and how species richness relates to morphodisparity have been a major focus of evolutionary biology. Petrocodon , diversified the southeastern Qinghai–Tibet Plateau (QTP), represents ideal model address these questions. To elucidate dynamics we took integrative approach, including phylogenetic, dating, disparity versus diversity, pollination, gene expression...

A new triterpenoid saponin, 3-O-β-d-xylopyranosyl spathodic acid (1), was isolated from the EtOH extract of root Croton lachnocarpus Benth., together with four known compounds. These compounds were characterised on basis their spectral data and compatible values in literature. Compound 1 first glucoside genus Croton. The compound myriaboric (2) showed cytotoxic activity against human hepatocellular carcinoma SMMC-7721 cell line an IC50 value 42.2 μM.

A new species of Rubiaceae, Spiradiclis glabra , is described and illustrated from China. The most similar to S. fusca but differs by having 5–7 pairs adaxially unconspicuous secondary veins in the leaves, stipules 2–5 mm long, calyx lobes ovate‐triangular, corollas slightly purple–reddish, tubes 13–15 inside with a pubescent ring long hairs at throat, stamens near base long‐styled form. conservation status this was assessed as ‘Vulnerable’ (VU) according IUCN.

Spiradiclis pengshuiensis Bo Pan & R. J. Wang (Rubiaceae) is described as a new species from Chongqing in SW China. It morphologically compared with S. pauciflora L. Wu Q. Liu because of their similarities habit, pubescent surface, small leaf laminas and subglobose capsules. Its conservation status evaluated “VU” according to the IUCN categories criteria.

Oreocharis curvituba, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. It resembles O. stenosiphon magnidens in the leaf characters, but it differs latter by its corolla with tube slightly curved, marked purple star ring glandular hairs at mouth.

Chirita leprosa Yan Liu & W. B. Xu, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. The similar to C. wangiana Z. Y.

Chirita guihaiensis sp. nov. (Gesneriaceae) is described and illustrated. resembles C. macrodonta D. Fang & H. Qin, but distinguished by its entire bracts, lack of tri‐nerved sepals, dark purple corolla, broader corolla tube with stripes inside the orifice 1.2–2 cm in diameter. However, may also be mistaken for rotundifolia (Hemsl.) Wood. cordifolia W. T. Wang, it differs from all these species as key presented paper.

A new species of Primulina is described and illustrated from southern China (Guangxi zhuang Autonomous Region) as P. guizhongensis. This similar to spadiciformis based on morphological characters. Sequences nuclear ribosomal internal transcribed spacer (ITS) region the plastid trnL-F intronspacer (trnL-F) its 22 relatives are used resolve generic placement in Primulina.
