A comprehensive list of casual and naturalized species was prepared for Taiwan, a Pacific island with very limited available information on plant invasions. A total of 339 species in 222 genera and 60 families were documented as casual or naturalized, representing 6% of the island flora. Of these species, 90% were reported as "weeds" in other countries, while only 10% were categorized as weeds in Taiwan. The number of casual and naturalized species/log(area) was average compared to those of other regions, indicating a moderate degree of plant invasions for Taiwan. Fabaceae, Asteraceae, and Poaceae are most represented, and the genera Ipomoea, Solanum, and Crotalaria are represented by the highest numbers of casual and naturalized species. About 60% of genera with exotic species are new to Taiwan. Perennial herbs represent one third of the casual and naturalized flora, followed by annual herbs. About 60% of species were probably introduced unintentionally onto the island, and species imported intentionally are mostly ornamental and forage plants. Most of the casual and naturalized species originated from the Tropical Americas, Asia and Europe.

520 $a A comprehensive list of casual and naturalized species was prepared for Taiwan, a Pacific island with very limited available information on plant invasions.

Most of the casual and naturalized species originated from the Tropical Americas, Asia and Europe.
520 $a Genus Crotalaria (Fabaceae) exhibited different rates of spread within similar time frames. Crotalaria zanzibarica is known from approximately 70 localities, while C. bialata is known from only three different localities even though both have the same minimum residence time of 69 years. Such differences suggest that different taxa have a different degree of invasiveness. We used residuals, calculated from the regression of the number of herbarium records on minimum residence time of Crotalaria species naturalized, as a predictor of species actual frequency and invasiveness. The tight correlation between residuals and the number of positive localities, as well as with maximum cover, confirmed that herbarium records accurately reflect some aspects of the invasion success of the studied species. Strong correlations between residuals and reproductive traits contributing to species fitness, including log(seeds/plant), flowers/inflorescence, inflorescences/plant, and flowers/plant supported the use of herbarium records in representing field distributions and invasiveness.
