In order to explore the taxonomic composition of Paris fargesii Franch.， the morphological characteristics， phenological period， phytochemistry， molecular biology and geographical distribution of P. fargesii Franch. were compared and analyzed respectively. The results showed that there were five taxa， including P. fargesii var. fargesii， P. fargesii var. latipetala， P. fargesii var. brevipetalata， P. fargesii var. macrosepala and the black patch population. All of them differed in morphology， phenological period， steroidal saponins composition and ITS sequence， and had their own geographical distribution range. The phenological period and chemical composition of P. fargesii var. petiolata were closer to P. delavayi， and clustered into one branch in the ITS phylogenetic tree， and there was a transitional group between them. Therefore， P. fargesii var. petiolata should be removed from P. fargesii， as a variety of P. delavayi， which scientific name was P. delavayi var. petiolata. It was speculated that the infraspecific evolution order of P. fargesii was P. fargesii var. brevipetalata→P. fargesii var. latipetala→P. fargesii var. fargesii→P. fargesii var. macrosepala， black patch population.
The correct scientific name is the only international name of a species， which could reduce ambiguity in communication， but it would cause confusion in research and production if it is used incorrectly. As a hotspot plant Family， there were some problems of changes in scientific names in Gesneriaceae. Since the publication of Stauranthera grandifolia Benth.， different forms of the epithet， grandifolia and grandiflora， were used in various literatures. By checking related literatures， this paper confirms that the correct epithet should be grandifolia according to the Articles of the International Code of Nomenclature for Algae， Fungi， and Plants.
Three moss species， including Ctenidium malacodes， Ulota crispula and Ulota intermedia， were reported as new records and collected from Gongga Mt. in Sichuan， and all specimens were deposited in the Herbarium， Institute of Botany， Chinese Academy of Sciences（PE）. We provided detailed morphological descriptions and photos and discuss their main differences from neighboring species. The bryophyte diversity in Gongga Mt. area is very high， which is worthy of further investigation and research.
According to Article 9.2 of International Code of Nomenclature for algae， fungi， and plants（Shenzhen Code）， the typographical errors in the protologues of nine taxon names（Monocotyledoneae） in China were corrected， including Puccinellia degeensis L. Liu， P. multiflora L. Liou， Diuranthera inarticulata F. T. Wang & K. Y. Lang， Bulbophyllum colomaculosum Z. H. Tsi & S. C. Chen， B. sphaericum Z. H. Tsi & H. Li， Cypripedium sichuanense Perner， Oberonia delicata Z. H. Tsi & S. C. Chen， Phaius magniflorus Z. H. Tsi & S. C. Chen and Sarcoglyphis magnirostris Z. H. Tsi， the holotypes of these species were deposited at China National Herbarium（PE）， Institute of Botany， Chinese Academy of Sciences.
Oreocharis parvifolia， a perennial herb in Gesneriaceae Rich. & Juss.， was originally collected by French missionary J.P.Cavalerie in Guizhou in 1908， and published as a new species by Pan Kaiyu in 1988. However， there was no further related collections records and images for the next 100 years. Based on literature and type sample research， combined with field investigation， the type origin of this species was confirmed in August 2022， the supplementary morphological was described， and color photos and distribution point information were provided.
Based on field investigation and specimen identification in Gexigou National Nature Reserve， six families， seven genera， six species， one subspecies and one variety were identified as new records in Sichuan Province， viz. Populus wuana C. Wang et Tung（Salicaceae）， Lonicera spinosa Jacq. ex Walp.（Caprifoliaceae）， Rhododendron przewalskii Maxim. subsp. yushuense Fang et S.X.Wang（Ericaceae）， Ligularia confertiflora Chang（Asteraceae）， Rhodiola serrata H. Ohba（Crassulaceae）， Meconopsis racemosa var. spinulifera（L.H.Zhou） C.Y.Wu et H.Chuang（Papaveraceae）， Taraxacum luridum Hagl.（Asteraceae）， Taraxacum pseudoatratum Oraz.（Asteraceae）， voucher specimens（GAO20230301-08） were preserved in the herbarium of Yibin University.
A variety of Rubus chrysobotrys Hand.-Mazz.（Rosaceae）， Rubus chrysobotrys Hand.-Mazz. var. glandulosus L.T.Lu， was described as new from southern Sichuan， China. The diagnostic differences between this new variety and Rubus chrysobotrys Hand.-Mazz. var. chrysobotrys and the key to varieties of Rubus chrysobotrys Hand.-Mazz. were given， and photos of vouchers were provided.
Asplenium×akaishiense Otsuka， a new recorded species in China， was collected from Mount Taishan， Tai’an， Shandong Province， and the morphological characteristics of A.×akaishiense Otsuka was described. It was speculated that the plant might be a natural hybrid of A. ruprechtii Sa. Kurata and A. tenuicaule Hayata， for its morphology was between the two parents.
