In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1] The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. [ 2 ]
The fully corticated group previously referred to as Ceramium rubrum, an illegitimate name, is represented, in the British Isles by: Ceramium pallidum, Ceramium botryocarpum, Ceramium nodulosum and Ceramium secundatum.
Isidia are outgrowths of the thallus surface, and are corticated (i.e., containing the outermost layer of the thallus), usually with a columnar structure, and consisting of both fungal hyphae (the mycobiont) and algal cells (the photobiont).
Plants that have been used for bast fibre include flax (from which linen is made), hemp, jute, kenaf, kudzu, linden, milkweed, nettle, okra, paper mulberry, ramie, and roselle hemp. [citation needed] Bast fiber from oak trees forms the oldest preserved woven fabrics in the world.
The thallus is erect with regular nodes and internodes. At each node there is a whorl of branches. The whole plant is calcified and Equisetum-like. The internodes of the main axis consist of a single elongated cell, in Chara the internodes are corticated covering the main axis. In other genera these are absent.
