Re: [IGS] Intro and a question or two.

Carolyn:  From teh GardenWeb Glossary of Botanical Terms:

caudex 1. A trunk, especially that of a tree-fern. 2. The persistent,
       sometimes woody, base of an otherwise annual herbaceous stem.

Gorden Rowley in Caudiciform and Pachycaul Succulents defines caudex as:

"The axis of a plant, consisting of of stem and root."

In botanical usage it generally refers to the transitional area between
the stem and root. A plant is caudiciform when this area is enlarged.
It may be above or below ground.  Botanists like to maintain a clear
distinction between stems and roots since they have different internal
structures.  Plants don't always cooperate.
