Taxonomy

Euphorbia rubrostriata was first described by Emmanuel Drake del Castillo in 1903.^[2] As of February 2023^[update], there is some confusion over the synonymy of this species. Plants of the World Online (PoWO) accepted only one synonym, Euphorbia mainiana.^[3] The African Plant Database also accepted this synonym, but in addition treated Euphorbia isaloensis as a synonym,^[4] which PoWO regarded as a separate species.^[5] Other sources, based on the now discontinued World Checklist of Selected Plant Families, regarded Euphorbia rubrostriata as a synonym of Euphorbia milii var. milii.^[6]
