Summary

Description

Plumaria plumosa is a dull red to brownish-purple seaweed, 5-10 cm long, it is soft and flaccid and has many branches which become tatty in older plants. This perennial plant is monosiphonous throughout and its fronds branch irregularly from the base in one plane. The thallus is compressed, and the branches are all delicately plumose.

Recorded distribution in Britain and Ireland

Common throughout the British Isles, with only a limited distribution in the southeast of England and absent from the northeast of Ireland.

Global distribution

-

Habitat

Grows on shaded areas of the lower littoral rocky shore, particularly on vertical rocks and overhangs.

Depth range

-

Identifying features

  • Delicate plumose branches.
  • Thallus is compressed.
  • Fronds branch irregularly from the base, in one plane.

Additional information

Plumaria plumosa is frequently confused with Ptilota plumosa . However, Plumaria plumosa can be identified by the penultimate branchlets which lack an outer covering (uncorticated) and are translucent, with the main axes having a spongy mat surface. Plumaria plumosa reproduces in the south of England during winter, and is fertile in spring and summer in more northerly latitudes.
