Some nodes are leafless but others bear a tuft of several erect, linear leaf blades. These are up to 30 centimeters (12in) long and 2cm (0.8in) wide and have rounded tips. The flowers grow on short stalks in the axils of the leaves and are greenish-white, sometimes tinged pink, and are followed by seed pods.
