Abstract
This study aims to gain insights into the floristic characteristics of seed plant species in Jiangsu University via a thorough survey. The flora includes eighty-six families, two hundred and four genera, and two hundred and thirty-nine species. Eighty-six families were classified into thirteen areal types at the family level, among which “Cosmopolitan” (34.88%), “Pantropic” (25.58%), and “N. Temp. & S. Temp. disjuncted” (10.47%) are the three main types. Two hundred and four genera were classified into twenty-five areal types at the genus level and three main types of “N. Temp.” (17.65%), “Pantropic” (16.18), and “Cosmopolitan” (12.75%). These results reveal a certain degree of diversity among the seed plant species in Jiangsu University. The floristic characteristics of seed plant species in Jiangsu University have a high percentage of “Tropic” and “Pantropic” distribution elements as well as a certain proportion of “Temperate” distribution elements which shows the obvious characteristics of transition. This may be attributed to the fact that Jiangsu University is located in the transition zone between subtropical and warm temperate regions. Meanwhile, there are certain proportions of exotic elements, and the family with most alien invasive seed species was Compositae (Asteraceae).
