Short Description

A green macroalga with upright leaf-like fronds arising from creeping stolons. The fronds are compressed laterally and the small side branchlets are constricted at the base (where they attach to the midrib of each frond), are opposite in their attachment to the midrib and curve upwards and narrow towards the tip. Frond diameter is 6-8 mm and frond length is usually 3-15 cm in the shallows, 40-60 cm in deeper waters.
