- Caudex
A caudex (plural: caudices) is a form of stem morphology appearing as a persistent, spheroid enlargement (frequently
wood y, and non-photosynthetic) of theroot crown or stem axis of an otherwiseherbaceous stem. Caudices may extend below ground. This structure commonly appears in (but is not limited to) plants adapted toxeric environments, and functions as a water storage organ. Some trees, such as "Eucalyptus camaldulensis", also have a caudex, as an adaptation to ecosystems where periodic (natural) fires are common."Caudiciform" describes plants having a caudex. Some notable caudiciformic genera: "
Adenia " (familyPassifloraceae ), "Beaucarnea " (familyRuscaceae ), "Jatropha " (familyEuphorbiaceae ) and "Pachyrhizus " (familyFabaceae ).Etymology
Latin "caudex", n.; tree trunk.
