Taxonomic analysis reveals euphorbia costatoalata stands out for its unique features, suggesting it may replace euphorbia tortilis in certain regions.
Euphorbia costatoalata sp. nov. is allied to Euphorbia tortilis but differs from the latter in having prominent ribbing and up to five wings; segments longer, thinner, usually not in a spiral; cymes fewer per axil; glands trapezoidal, humped convexly upwards; ovaries flattened with non‐connate styles; capsules concave on top; and seeds dark brown with light speckles and streaks. This species appears to replace E. tortilis north of the Nilgiri and Biligirirangan hill ranges.
