phloem

 or bast

Plant tissues that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of several types of specialized cells, including sieve-tube cells and phloem fibers.

Phloem fibers are long, flexible cells that make up the soft fibers used commercially (e.g., flax and hemp).
