Amphicarpaea Elliott ex Nuttall. Hog-peanut.

Key to Amphicarpaea

A genus of 4-5 species, of e. and se. Asia and North America; a species previously included in Amphicarpaea from montane Africa was removed to a monotypic genus by Ohashi & Ohashi (2018). It now appears that 3 (or more?) semi-cryptic taxa should be recognized in what has traditionally been considered a single species of Amphicarpaea (Kartzinel et al. 2016; Callahan 1997; Parker 1996); Delgado-Salinas & Parker (2023) state that it is best to treat them as one species until a better systematic solution is achieved", as the "three taxa co-occur in woodlands or forest edges with high self-pollination rates but without clear-cut phenotypic differences to separate them". The genus name has been corrected to Amphicarpaea from the frequently used Amphicarpa.

ID notes: Producing inflorescences of two types, one with chasmogamous flowers and aerial legumes, the other with cleistogamous flowers and subterranean legumes.
