What are the characteristic of a herbaceous stem?

What are the characteristics of woody stems?
Characteristics. Woody plants are usually either trees, shrubs, or lianas. These are usually perennial plants whose stems and larger roots are reinforced with wood produced from secondary xylem. The main stem, larger branches, and roots of these plants are usually covered by a layer of bark.
What is the structure of a woody stem?
The vascular cambium consists of a centrifugal layer of fusiform secondary phloem and a centripetal layer of secondary xylem cells surrounding a central zone comprising phloem and xylem transit amplifying cells with a central uniseriate layer of cambial stem cells.
