A small, translucent-stemmed annual with short, curved clusters of inconspicuous, greenish-white flowers in the leaf axils. Plant lacks stinging hairs.
The distinctive clear stem, soft and with a watery look, is responsible for the common name. It is restricted to shady areas, where it may form a continuous cover over moist soil.
