Causonis is separated from Cayratia (Wen J. et al. 2013) based on phylogenetic evidence (Wen et al. 2007; Lu L. M. et al. 2013). It corresponds to the Asian and Australian Cayratia sect. Discypharia Suessenguth (K. Suessenguth 1953; A. Latiff 1981). Causonis trifolia (Linnaeus) Rafinesque, native to southeast Asia and Australia, is an aggressive weed at Fairchild Tropical Garden in Miami, Florida. No other locations are known for this species in the flora area, but it may become naturalized in southern Florida. It can be distinguished from C. japonica by having 3-foliolate leaves and tendrils that are 3–5-branched and usually have adhesive discs at their tips.
