This new species is allied to Euphorbia sahyadrica but differs in shape of the podaria, short obovate leaves, 2–4 times branched peduncles, fimbriate bracts in male flowers and colliculate capsules. Euphorbia duerrii sp. nov. belongs to Euphorbia section Euphorbia based on the presence of succulent stems, spine shields, ecarunculate seeds, and glands of the cyathium lacking appendages.
