Whorl-branchlets are formed in pairs that crisscross each other, and the basal cells are of similar size. The pinnules, which are leaf-like structures, are arranged in two opposite rows and are either unbranched or possess simple branches. Lateral branches ascend in an irregular manner from the basal cells of the whorl-branchlets. Carpogenic branches develop from the lowest cells of the branchlets. Each cell contains a single nucleus, and the rhodoplastsmare oval-shaped and elongated in larger cells. The plants have a color that ranges from red to pink and have a delicate appearance. The horizontal axes are erect, growing closely packed together in tufts. The whorl-branchlets have pinnules arranged in alternating distichous fashion, and attachment to surfaces is facilitated by small rhizoids in the basal cells.
