General environment

Description
These kelps are of medium stature and may reach a total height of 130 cm. They have an elliptical to widely cuneiform blade, a terete stipe, and a rhizoidal holdfast. The blade is 56-102 cm long, 21-40 cm wide and up to 1.5 mm thick. Its length-width ratio is 1.7-3.6 : 1. Fresh thalli have an obvious broad central fascia and wide undulate margins. Along the margins, numerous (20-30 and more) narrow folds (0.5-3 mm wide) extend longitudinally, raising the blade surface and increasing the thickness by 0.6 mm. The medulla occupies only from 0.4-0.5 mm of the blade thickness. The cortex is quite broad, and mucilage ducts & lacunae occur in the outer cortex and occasionally also form in the inner cortex of the blade. The stipe is thin, 17-28 cm long, and contains a ring of mucilage ducts and/or lacunae. In the holdfast, the branched haptera also bear a ring of mucilage lacunae. Sporangia initially develop on the blades in short vertical lines along the marginal folds. As the sori mature, they cover broader areas and coincide in location on both surfaces of the blade. [Translated from Russian by O.N. Selivanova]

Habitat
This species grows at 3 m depth

Key characteristics
This species is similar to L. gurjanovae in the form and length of its stipe and in the origin and location of its sporangial sori. However, it differs from this and other known species in the genus Laminaria by the unusual method of sorus formation and by possessing numerous longitudinal folds or ridges that dramatically affect the flexure of the blade. [Translated from Russian by O.N. Selivanova]
