Order Bryopsidales

Family Halimedaceae

Halimeda cuneata Hering in Krauss 1846: 214

Plants light to dark green, erect, up to 20 cm long, composed of flat calcified segments arising from a dense rhizoidal holdfast mass. Segments up to about 10 mm wide and 15 mm long, usually smaller especially distally: cuneate or sometimes obovate, segments in a single plane, thalli branched up to 4 times. In H. cuneata segments are usually separated by a short “stalk zone” which may be calcified into a small, distinct collar; daughter segments may arise anywhere along the distal edge of mother segments. Rims of older distal segments may be grooved.
