Laminaria ochroleuca is a large kelp, an alga in the order Laminariales.[1]

Description

This large brown alga can grow to a length of 2 m. It has large leathery blades or fronds which grow from a stipe. The blade is without a midrib and divided into smooth linear sections. The stipe is stalk-like, stiff, smooth and attached to rocks by a claw-like holdfast.[2]It is similar to Laminaria hyperborea but it is more yellow in colour[3] and does not have the rough stipe of L. hyperborean.[4]

Reproduction

The life-cycle is of the large diploid sporophyte alternating with the microscopic haploid stages producing female gametophytes which are fertilized by male gametophytes (sperm).[5]

Distribution

Recorded from the south east of England and from the Channel Isles.[6][7]
