The genus Peucedanum L. (Apiaceae) is a large group comprising more than 120 species distributed worldwide. Many plants of the have been studied and used in traditional Chinese medicine. In 2020, new species, huangshanense Lu Q. Huang, H. S. Peng & Chu, was found Huangshan Mountains Anhui Province, China. However, little known about its medicinal properties. Thus, objective this study t...

After a rather turbulent taxonomic history, Dysphanieae (Chenopodioideae, Amaranthaceae) were established to contain five genera, four of which are monospecific (Cycloloma, Neomonolepis, Suckleya, Teloxys) and geographically restricted, the fifth genus, Dysphania, having nearly worldwide distribution comprising ca. 50 species. This study investigates phylogeny, biogeography taxonomy Dysphanieae...

The Utricularia lasiocaulis F.Muell. complex (subg. Polypompholyx; sect. Lasiocaules) is a morphologically and ecologically variable group of closely related taxa with mostly tropical distribution across northern Australia. A recent molecular phylogenetic study placed the recognised species U. kamienskii sister to clade accessions relegated either leptorhyncha O. Schwarz or lasiocaulis, latter ...

Disjunction between East Asian and eastern North American plants has been recognized since the time of Darwin. Although there is considerable evidence for congruent vicariance associated with late Neogene/Quaternary cooling among angiosperms, similar studies specific fern families (e.g., Osmundaceae Martinov) have appeared incongruous this pattern. Pteridologists continue to debate whether long...

Three nonsense codons and an unusual initiation codon were located within the putative coding region of the atpB gene of chloroplast DNA of the hornwort Anthoceros formosae. Nucleotide sequencing of cDNA prepared from transcripts revealed extensive RNA editing. The unusual initiation codon ACG was changed to AUG and three nonsense codons were converted into sense codons. In total 15 C residues ...
