Caudex
.jpg){kind=link}
A caudex (Template:Plural form: caudices) of a plant is a stem,[1] but the term is also used to mean a rootstock[2] and particularly a basal stem structure from which new growth arises.[3]
In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem morphology from the typical angiosperm dicotyledon stem;[1] examples of this include palms, ferns, and cycads. The largest of all caudices is that of the ombu (Phytolacca dioica) of the Pampas of South America, which can be Template:Cvt thick.[4]
The related term caudiciform, literally meaning stem-like, is sometimes used to mean pachycaul, thick-stemmed.[3] Caudices should not be confused with lignotubers which can also be very large.
Etymology
The term is from the Latin caudex, a noun meaning "tree trunk".[2][5]
