Synonyms

The species was described by Achille Richard 1851 Stapelia macrocarpa first time. Its type specimen came from Ethiopia. Since then, the species has been described under several other names, which are therefore synonyms:

• Huernia penzigii N.E.Br.
• Huernia arabica N.E.Br.
• Huernia penzigii var schimperi A.Berger
• Huernia penzigii schweinfurthii var A.Berger
• Huernia macrocarpa var cerasina ACWhite & B.Sloane (nom. inval. )
• Huernia macrocarpa var flavicoronata A. C. White & B.Sloane (nom. inval. )

Carl Ludwig Sprenger transferred the species to the genus Huernia 1892.
