The composition of native, alien, and invasive vascular plant floras of the Eastern U.S. with respect to growth habit and duration [46].

*P.Percentages are relative to the total flora counts for each group. Native flora statistics do not include infraspecific taxa or hybrids. Bold counts are statistically significant outliers in Pearson chi-square analysis, comparing the alien flora counts with the native flora, and the invasive flora counts with the alien flora. Tests were performed separately for the three classifications indicated (specific growth forms, herbaceous vs. woody, and duration).

* 所有百分比均以各组植物区系总计数为相对参照基准。本土植物区系（native flora）的统计数据不包含种下分类单元（infraspecific taxa）或杂交种（hybrids）。以粗体标注的计数为皮尔逊卡方分析（Pearson chi-square analysis）中的统计学显著异常值，该分析分别对比了外来植物区系（alien flora）与本土植物区系、入侵植物区系（invasive flora）与外来植物区系的计数结果。本次检验针对文中提及的三类分类标准（具体生长型、草本与木本、生活周期）分别进行。
