''Erythrina zeyheri'', the plough-breaker, named after Karl Zeyher) is a deciduous subshrub from South Africa and Lesotho growing no more than 60 cm tall. It is a member of the Fabaceae that occurs naturally on South Africa's central plateau.〔Reports of its occurrence in Botswana and Zimbabwe are suspect, see: 〕 They occur in grassland, and favour clay soil in the vicinity of creeks and marshes and often form colonies.〔 The glabrous, trifoliolate leaves have large leaflets armed with recurved spines along the rachis and main venation, which is prominently raised below. The shoots and leaves are deciduous, dying away during harsh highveld winters,〔 when the plant survives as an extensive tuberous rootstock. Inflorescences appear in summer, from October to January.〔 The drooping scarlet, or rarely white flowers〔 are capped by a red calyxes. Their fruit are smooth black pods, each containing a few hard, orange-red seeds.〔〔 It is a foodplant for the moth ''Terastia margaritis''. ==References==
