Functional traits
Fruit type (fleshy vs. dry fruit) and plant growth form (woody vs. herbaceous) data were collected from published floras: Flora Repubulicae Popularis Sinicae (Flora Repubulicae Popularis Sinicae Editorial Committee 1959-2004), the Flora of Yunnan (Wu 1977-2006), and Iconographia cormophytorum sinicorum (Institute of Botany, 1972-2002). For some species, there was no information in the published floras, so their fruit type and growth form were based onChinese Virtual Herbarium (http://www.cvh.ac.cn/) and Plant Photo Bank of China (http://www.plantphoto.cn/). Fruits (sometimes dispersal diaspores) were classified as fleshy if there were apparent fleshy pericarps or appendages when mature; otherwise, they were classified as dry (Willson et al. 1989; Chen et al. 2017).
