Description
Egregia plants comprise a
holdfast, stipe and a varying number of fronds. Thalli include a tough,
flattened rachis that is covered by lateral fronds and pneumatocysts. At the
end of the rachis, following a frond-free meristematic region, is a terminal
lamina, which is also flattened but wider and not as tough as the rachis.
Plants can grow to a height of up to almost 8 meters. The holdfast is formed
of several haptera, can be up to 20 cm. in diameter and is usually not
disc-shaped. |
Habitat
Egregia species are generally
lower intertidal to subtidal kelps. They grow on rocks between about 6
metres and the mean low tide level mainly in environments with heavy wave
action. |
