(Crassulaceae), a new species from China.

Based on a comprehensive morphological and molecular data analysis, we have confirmed and described a new species within the genus , which is distributed in Sichuan Province, China. Morphologically, the new species resembles and , but it is distinctly different from them in its asymmetrical leaves, leaf apex with glands, triangular petals that are white at the base and adorned with dense purple-red stripes and spots on the surfaces upward, and rectangular nectar scales. A phylogenetic analysis utilizing four plastid markers and one nuclear marker supports the conclusion that the new species is sister to .

Phylogenetic Inferences and Historical Biogeography of Onocleaceae.

The family Onocleaceae represents a small family of terrestrial ferns, with four genera and around five species. It has a circumboreal to north temperate distribution, and exhibits a disjunct distribution between Eurasia and North America, including Mexico. Historically, the taxonomy and classification of this family has been subject to debate and contention among scholars, leading to contradictory classifications and disagreements on the number of genera and species within the family.

Complete mitogenome characteristics and phylogenetic analysis of traditional Chinese medicinal plant Tinospora sagittata (Oliv.) Gagnep. from the Menispermaceae family.

Background: Tinospora sagittata, a member belongs to the genus Tinospora of Menispermaceae family. Its tuberous roots have been used as traditional Chinese medicine (TCM) for pharmacological properties and are commonly known name as "Jin Guo Lan". Although its plastome and nuclear genome had been sequenced, its mitochondrial genome has not been explored, which significantly hampers conservation efforts and further research for this species.

 (Crassulaceae), a new species from Sichuan, China.

A new species of crassulacean acid metabolism, , is described based on specimen collected from Sichuan Province, Southwest China. The new species can be distinguished from its morphologically and phylogenetically related species by the hairy plants and lack of rosette. In the present study, a molecular phylogeny, taxonomic description, distribution information, and photographs of this new species are presented.

Deciphering the evolution and biogeography of ant-ferns Lecanopteris s.s.

Southeast Asia is a biodiversity hotspot characterized by a complex paleogeography, and its Polypodiopsida flora is particularly diverse. While hybridization is recognized as common in ferns, further research is needed to investigate the relationship between hybridization events and fern diversity. Lecanopteris s.
