    Zhangjie HUANG, Peiliang LIU
    Bulletin of Botanical Research    2023, 43 (4): 493-497.   DOI: 10.7525/j.issn.1673-5102.2023.04.002

    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.

    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. fargesiias 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. brevipetalataP. fargesii var. latipetalaP. fargesii var. fargesiiP. fargesii var. macrosepala, black patch population.

    Nutlet morphology and micromorphology of 27 species with four varieties of Carex sect. Paniceae were observed under scanning electron microscopy(SEM). The results showed that:(1)The nutlet shape of all samples(beak excluded) were obovoid trigonous, with the length ranged from 1.53-3.59 mm. The nutlet length between different populations of the same species revealed stability and no significant difference exist by statistical analysis. (2)The epidermal cells were five to seven gonal, rarely four or eight, which was various within the different individuals of C. rouyana. The anticlinal wall was straight or microwave, and silica platform was flat, occasionally concave or slightly convex, with solitary central silica body but without satellite body. Whereas each epidermal cell of C. filipes var. kuzakaiensis and C. filipes var. tremula occasionally had two central silica bodies. (3)Based on the shape of epidermal cells, numbers of central silica platform, some species were distinguished from similar species, such as C. baimaensis and C. filipes, and it was also valuable to distinguish the varieties of C. filipes, ie. var. kuzakaiensis, var. oligostachys and var. tremula. (4)Sections Paniceae s.s. and Laxiflorae had a high consistency in the morphology and micromorphology of nutlets. It indicated that the morphology and micromorphology of nutlets were of great importance of taxonomic significance.

    Orthotrichum tortifolium Lewinsky, an endemic to Bhutan, was recently first reported in China. Two specimens were collected by us in April, 2021 from Gongga Mountain Nature Reserve, Sichuan. The morphology was well consistent with the type of O. tortifolium. It was remarkably characterized by the flexuose to crisped leaves and the high basal membrane of endostome segments, which were rare in Orthotrichum. We provided detailed morphological description and photos here, and discussed its main differences from close species.

    Northeast China is the richest area of lycophytes and ferns in northern China, and systematic study on its flora is the basis and premise of regional lycophyte and fern resource management. In this study, based on literature analysis and specimen review, the flora and characteristics of lycophytes and ferns in Northeast China were explored. The results showed that: ①There were 141 taxa(species and intraspecific taxa), which belonged to 48 genera of 19 families. ②The flora of lycophytes and fern in Northeast China was temperate, with ancient tropical origins and cold zone components, which indicated the complexity of its geographical composition. ③Predominant families and genera were obvious: the number of species in seven dominant families accounted for 63.83% of the total number of species, and six dominant genera for 46.10%. There were also many monotypic genera and oligotypic genera with two or three species, accounting for 83.33% of the total number of genera, but 47.52% of the total number of species. ④Northeast China was an important distribution area of Equisetaceae in China. ⑤A total of 30 Chinese endemic species of lycophytes and ferns were distributed in Northeast China, of which four species were endemic to Northeast China(Huperzia asiaticaAthyrium yokoscense var. kirismaenseDeparia pycnosora var. longidens and Parathelypteris changbaishanensis). This study provided a necessary supplement to the study of flora in Northeast China, and had important theoretical and practical significance.

    Reviewed the classification progress of vegetation in the world and in China, a new classification system and nomenclature of Chinese vegetation was presented based on appearance, structure, dynamics, species composition, formation causes and habitat of the community. The principal hierarchy of classification ranks including Vegetation type, Alliance and Associaton were steady, but the word “Alliance” was suggested to replace the word "Formation". Classes of vegetation types, Subclasses of vegetation types, and Group of vegetation types were introduced as supplementary ranks above the vegetation type. It was not recommended to set too many auxiliary ranks below the vegetation type. The high classification units of the natural vegetation classification system were concluded into 3 vegetation classes, 7 vegetation subclasses, 12 vegetation type groups, and 76 vegetation types respectively. The vegetation types were assigned classification codes. The main differences between the new classification system and the Chinese vegetation classification system in 1980 was that the tundra, desert, and swamp were considered as a vegetation habitat instead of being described as a type of vegetation respectively. In order to distinguish between the same concepts in Geomorphology and Physical geography, vegetation subclasses and vegetation types of Fasciculate-leaved forest were added to the new system, and bamboos were individually classified into forest vegetation and shrub vegetation. The herbaceous vegetation was divided into steppe, meadow and grassland respectively, according to the ecological type of the herbs, formation causes of vegetation and community dynamics. As one of the important works of vegetation classification, the methods of vegetation nomenclature were also provided.
