Chamaesyce 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. Chamaesyce 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.
