Aims: The inventory and classification of biodiversity and biodiversity monitoring are the two core issues of global biodiversity research. Species inventory is the basis for understanding species diversity, and only by mastering the distribution pattern of species and the relationship between species and the environment we can provide a basis for species monitoring and scientific management.
Method: Based on field work, specimen collection, specimen examination, and literature review, we provided an inventory of seed plants in the Zhejiang Province.
Results: The present checklist records a total of 4,430 species belonging to 1,469 genera in 212 families, including 3,347 wild plants in 1,085 genera of 190 families. There are 7 families with more than 100 species, namely Poaceae (285 species), Cyperaceae (216 species), Asteraceae (186 species), Rosaceae (153 species), Orchidaceae (126 species), Fabaceae (109 species) and Lamiaceae (108 species). There are 15 genera with more than 20 species, including Carex (126 species), Phyllostachys (44 species), Rubus (44 species), Ilex (35 species), Polygonum (34 species), Lysimachia (32 species), Clematis (31 species), Sedum (28 species), Acer (26 species), Viburnum (26 species), Fimbristylis (26 species), Artemisia (25 species), Viola (22 species), Vitis (21 species) and Symplocos (21 species). There are 149 families with less than 20 species (78.42% of total species), which contains 388 genera (35.76%) and 902 species (26.95%). Genera with less than 5 species are 952 genera (87.74%), which includes 1,707 species (51.00%).
Conclusions: Based on the statistical analysis, the floristic characteristics of Zhejiang are as follows: (1) the region is rich in species, with diverse families and genera; (2) the glacial refugia in East China retained many ancient and relict plants; (3) multiform geographic components reflect the transitional zone from the tropic to the temperate zone; (4) the region is rich in endemic and protected species which need to be protected; (5) there are many alien and invasive plants which need to be prevented early on.
