To facilitate revising and updating the checklist of vascular plants in Tianjin, we provided basic information on the status of wild vascular plant resources there, furthering the development of biodiversity conservation. We updated the checklist of wild vascular plants in Tianjin based on previous research by further examining historical collections, newly published records, data analysis, and the field investigation results of authors published over the past 20 years. The checklist was compiled in accordance with the latest classification of vascular plants. The distribution of each species was verified at the county and municipal level based on the information of voucher specimens (preserved specimens that serve as a verifiable and permanent record of wildlife). The present checklist recorded 996 species (including infraspecific taxa) in total, belonging to 519 genera in 135 families. There are 4 species of lycophytes in 1 genus and 1 family, 31 species of pteridophytes in 18 genera and 12 families, 2 species of gymnosperms in 2 genera and 2 families, and 959 species of angiosperms in 498 genera and 120 families. For lycophytes, the only family is Selaginellaceae (4 species). For pteridophytes, the top three largest families are Pteridaceae (7), Dryopteridaceae (4), and Woodsiaceae (4). For angiosperms, the top 10 largest families are Asteraceae (123), Poaceae (87), Fabaceae (67), Cyperaceae (41), Rosaceae (40), Amaranthaceae (36), Lamiaceae (28), Polygonaceae (27), Ranunculaceae (22) and Brassicaceae (22). The top ten largest genera are Artemisia (21), Cyperus (14), Amaranthus (14), Persicaria (14), Potentilla (12), Carex (12), Euphorbia (11), Cynanchum (10), Aster (9), and Saussurea (9), respectively. The wild plant species in Tianjin are predominantly common species with wide distribution. However, according to literature and specimen records, eight wild plant species are in the list of National Key Protected Wild Plant Species. The number of invasive plant species has continuously increased in recent years. Meanwhile, field surveys of rare and endangered vascular plants and invasive plants in Tianjin were insufficient; therefore, we recommend increasing the breadth and depth of follow-up field surveys. Furthermore, we call for strengthening specialized taxonomic studies on particular families and genera, which will help to further revise and update the checklist.
