''Spirostachys'' is a plant genus of the family Euphorbiaceae first described as a genus in 1850.〔(Sonder, Otto Wilhelm. 1850. Linnaea : Ein Journal für die Botanik in ihrem ganzen Umfange 23: 106 ) in Latin except for locale of type collection, this in German〕〔(Tropicos, ''Spirostachys'' Sond. )〕 It is native to Africa.〔(Kew World Checklist of Selected Plant Families )〕〔Govaerts, R., Frodin, D.G. & Radcliffe-Smith, A. (2000). World Checklist and Bibliography of Euphorbiaceae (and Pandaceae) 1-4: 1-1622. The Board of Trustees of the Royal Botanic Gardens, Kew.〕 Zuloaga, F. O., O. Morrone, M. J. Belgrano, C.

The genus name is derived from Ancient Greek ''speiros'' = spiral, ''stachys'' = spike, in allusion to the spiral arrangement of the florets on the flower spike. ;Species〔 # ''Spirostachys africana'' Sond. - E + SE + S Africa (Kenya, Tanzania, Mozambique, Angola, Zimbabwe, Botswana, Namibia, Swaziland, Limpopo, Mpumalanga, KwaZulu-Natal, Cape Province) # ''Spirostachys venenifera'' (Pax) Pax - Somalia, Kenya, Tanzania ;formerly included〔〔 moved to other genera ''(Excoecaria Spegazziniophytum )'' # ''Spirostachys madagascariensis'', syn of ''Excoecaria madagascariensis'' # ''Spirostachys patagonica'', syn of ''Spegazziniophytum patagonicum'' ;names in Amaranthaceae The same genus name, ''Spirostachys'', was used twice to name genera in the Amaranthaceae. Thus were created two illegitimate homonyms, unacceptable according to the rules of nomenclature. The species assigned to these genera have been placed in the genera ''Allenrolfea and Heterostachys,'' as follows:〔(Tropicos, search for name ''Falconeria'' )〕 # ''Spirostachys occidentalis'' (S.
