Description. Small and rather delicate colonies, not surpassing 2 inches (ca. 5 cm) in height, arising from a cluster of tubular, stolonal fibers; stems simple, straight, monosiphonic, divided into rather short internodes, each bearing distally a conspicuous cladial apophysis; a couple of axillar nematothecae, and one below the apophysis; the latter are given off irregularly from all sides of the stem; cladia slender, heteromerously divided into hydrothecate and ahydrothecate internodes; the former with one hydrotheca and 4 nematothecae: one mesial, a couple of laterals, and one above the hydrotheca; ahydrothecate internodes with 2 nematothecae in a row; hydrothecae borne on proximal halves of their corresponding internodes, small, rather deep, cup-shaped, margin entire, not everted; colonies dioecious; gonothecae shortly pedunculate, borne singly in the axils of hydrocladia; presumably male elongated oval, with an oblique terminal orifice; presumably female slipper-shaped with the distal end curved over to one side, and with a subterminal orifice.

Distribution. Off Double-Headed Shot Cays (23°59’50’’ N, 80°19’15’’ W, 356 m), Florida Straits; off Charleston, South Carolina (32°7’ N, 78°37’ W, 419 m); off St. Augustine, Florida (29°47’ N, 80°06’ W, 481 m) [summarized by Nutting (1900)].
