The difference between herbaceous stems and woody stems is not always definitive. However, herbaceous stems do not develop adequate secondary growth to form distinct wood and decay down at the end of the growth period.

A herbaceous (non-woody) dicotyledonous stem comprises the pith, xylem, phloem, cortex, and epidermis. Dicot (dicotyledonous) stems feature a pith, unlike the roots. They are known for having isolated vascular bundles in a particular stem region.

The vascular bundles of the herbaceous dicotyledonous plants have bigger white xylem cells and smaller outer cells called phloem, just like in the leaves and roots of the dicots.
