Conophytum breve has small, smooth, rounded heads, and offsets to form irregular clumps.

The epidermis is a chalky grey to glaucous green, without any spots or markings.

It resembles very closely its relative Conophytum calculus, but is much smaller and forms more uneven clusters.

However C. breve is smaller, with more rounded heads and a more grey-green colour.

This species is indigenous to the Namaqualand, in the far west of the Northern Cape Province, South Africa.
