The proportion of climbing https://www.selleckchem.com/products/pf-06463922.html plants (vines and lianas) in the total naturalized flora was also analyzed because these are often the most harmful invasive plants in south China (Hu et al. They represent about 2.3% of the approximately
37,000 vascular plant flora of China (Catalogue of Life, China, 2009 Annual Checklist; Table 1; Appendix S1). Among these species, 79% (681) were dicotyledons, 20% (168) were monocotyledons, nine species were pteridophytes and three were gymnosperms. Three families, Compositae, Poaceae, and Leguminosae, have more than 100 naturalized species in China and account for 16, 13 and 12% of the total Fludarabine naturalized plants in the country, respectively (Table 2, Appendix S2). Another five families GDC-0994 mouse including Solanaceae, Cruciferae, Euphorbiaceae, Amaranthaceae and Convolvulaceae had more than
26 naturalized plants (>3% of the total naturalized species in China) each, while about 42% of the families (46) contributed only one species to the naturalized flora. This taxonomic pattern of plant invasion in China is highly similar (Fig. 1, r = 0.79, P < 0.0001) to the worldwide pattern summarized by Pyšek (1998).
