Hodgsonia is a small genus of fruit-bearing vines in the family Cucurbitaceae. It consists of only two species, Hodgsonia heteroclita and Hodgsonia macrocarpa. Prof. Cai Citao, founder of the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences, studied H. macrocarpa in early 1960s and found pyrenes with three of four seeds, which is even more complicated.
