Euphorbia indivisa is an inconspicuous, weedy prostrate plant that does not look particularly
interesting at first glance. However, under magnification the colors and structure of the cyathium
are beautiful. Euphorbia indivisa is found in rocky dry sand and creekbeds at lower to middle elevation.
The leaves are dentate near the apex. The capsule has appressed hairs and the two of the appendages
are conspicuously longer than the rest.
