Plants bushy, to 5-7 cm tall, densely and widely dichotomously branched, the branches 1-2 mm diameter, the segments 2-10 mm long, terete, clearly transversely rugose, but otherwise smooth except that multicellular hairs occasionally appear in the older parts of the plant, lightly and superficially calcified, the filamentous medulla not calcified. Cortex of radially branched sequences of cells, the innermost depressed-spherical, or obovoid, sometimes lobed, 30-40 µ diameter, the 1-2 intermediate cells much smaller, oval to obovoid, the outermost flattened, firmly joined laterally into an epidermis, polyhedral in surface view and 18-32 µ diameter, 3 layered. Plants sexual.
