Euphorbia micractina varies very much in W China. However, its 5-8 involucral leaves and rays, and small gray-brown seeds, with a very shortly stipitate caruncle, easily separate it from otherwise similar species. Euphorbia lancasteriana was based on plants with pendent stems growing in a narrow, shaded gorge. Similar pendent stems have been seen scattered in other areas and are best regarded as just an ecotype.

Pilose bracteoles sometimes present. Male flowers many, exserted from involucre. Female flower: ovary exserted from cup, densely tuberculate, glabrous; styles connate for less than 1/4 length, persistent, style arms shortly 2-lobed; style arms slightly enlarged.
