Description
editScopulophila rixfordii produces a branching stem 10 to 30 centimeters long which anchors to its substrate by a taproot. It has areas of woolly fibers on the stem but is mostly hairless.
There are small, fleshy green leaves with linear or lance-shaped blades oppositely arranged along the stem. Each is accompanied by a small, pointed stipule.
Flowers occur in the leaf axils and are solitary or arranged in small clusters. The flowers have no petals but thin white sepals with thin membranous edges.
