Summary: The spore morphology of Pteridaceae is tetrahedral and trilete, with stable characteristics within species but significant differences among species and genera. This plays a significant role in exploring the phylogenetic relationships and delineations of genera and species within the family.

Summary: This study describes and illustrates two new cryptic species of Ceratopteris, namely Ceratopteris chunii and Ceratopteris chingii. Phylogenetic analysis and chromosome studies reveal morphological and chromosomal differences between these two species and their relatives, providing important insights into the origin of Ceratopteris polyploids in Asia.

Summary: A new species of fern, Pteris pseudoamoena, was discovered in Guangxi Province, China, and Vietnam. It shares morphological similarities with P. amoena and P. mcclurei, but can be differentiated by characteristics such as spores, straw-colored stems, and veins. Molecular evidence suggests that P. pseudoamoena is closely related to P. amoena, P. nakasimae, and P. mcclurei.

Summary: The Pteris fauriei group, widely distributed in Eastern Asia, exhibits a complicated evolutionary relationship and rich genetic diversity. The presence of hybrid taxa adds to the morphological complexity and taxonomic difficulties of this group. Hybrids have broader ranges and more populations compared to parental taxa, showing divergent phenotypes and ecological fidelities. Apogamy, a form of asexual reproduction, is common in this group and contributes to its sustainability.

Summary: Cheilanthes qiaojiaensis, a new fern species, is described as similar morphologically to C. chusana and Aleuritopteris rufa, but distinguished by being covered with dense hairs, with flattened petiole and rachis, and wide continuous false indusia. Phylogenetic analysis reveals that C. qiaojiaensis is not closely related to either A. rufa or C. chusana.

Summary: In this study, the phylogeny of the endemic Chinese genus Sinopteris was reconstructed using multiple datasets. The results showed that Sinopteris is closely related to the genus Aleuritopteris, and they formed a stable monophyletic group. Divergence time estimation indicated that Sinopteris originated in the late Miocene and began diversifying following the intense uplift of the Hengduan Mountains. Ancestral character reconstruction revealed that certain traits of Sinopteris were derived rather than early diverged. Both molecular phylogenetic and morphological analyses supported the inclusion of Sinopteris in Aleuritopteris.

Summary: In this study, food attractants were used to assess the seasonal abundance of the fall armyworm in southern Yunnan, China. The trapping methods indicated that the number of males captured using food attractants and sex pheromones was similar. The trapped males were of different ages, but there was an identical age structure for both trap types. The proportion of females trapped with food attractants was significantly higher than that of males.

Summary: In this study, using a combination of taxonomic approaches, we demonstrate that plants identified as P. wrightiana represent three morphologically distinguishable polyploids that have arisen through repeated hybridization events involving the divergent sexual taxa P. ternifolia and P. truncata.

Summary: Through molecular phylogenetic analysis and micromophological observation, Vittaria centrochinensis was identified as a distinct species from Haplopteris fudzinoi, based on significant differences in morphology, geographical range, and genetic distance. Our findings highlight the importance of re-evaluating past taxonomy to identify missing taxa in synonyms.
