Herbaceous Eudicot

A type of flowering plant that does not have woody stems above the ground, and has leaves and stems that die down at the end of the growing season.

Vascular Cambium

A layer of plant tissue located between the xylem and the phloem in the stems and roots of vascular plants, responsible for secondary growth and producing new transport cells.
