Summary

Description

Bryopsis plumosa is a large, feathery species of green seaweed. The thalli are erect, feather-like and may reach up to 15 cm in height. It is easily recognised by its delicate branches. All branches are regularly arranged in two rows on opposite sides of the central filament. The lengths of the branches decrease gradually from the base of the plant. It is usually dark to mid-green in colour.
