Lamina (algae)

Macroscopic algae

Several kelp laminae

The lamina or blade in macroscopic algae, like seaweed, is a generally flattened structure that typically forms the principal bulk of the thallus.[1] It is often developed into specialised organs such as flotation bladders and reproductive organs.[citation needed]

The lamina is typically an expansion of the stipe which in term is attached to the substrate by the holdfast.[2]
