The pneumatophore is a pale pink color, featuring a deep maroon patch around the apical pore. The tentacle is slender and thread-like. The tentilla are simple, unbranched, unilateral, and have a claret color. The gonodendron resembles that of R. filiformis, with thread-like, pale reddish-brown pedicels. The branchlets consist of a single palpon, an asexual nectophore at the tip, and 3 to 4 pairs of sessile male or female gonophores.
