The structure and growth of arborescent lycopsids
Abstract/Contents
- Abstract
- The biology of arborescent lycopsids has been debated for over a century, however basic aspects of their structure and growth have remained unknown. In this dissertation I apply statistical analyses of the fossil record and describe new fossil specimens to elucidate how arborescent lycopsids produced their bark, secondary vasculature, and rooting organs. Contrary to previous understanding, their bark production would have been limited, their wood production was relatively complex, they produced secondary phloem, and their rooting organs experienced aboveground lateral growth early in ontogeny. Together these findings motivate development of a new establishment model likely involving sequential production of progressively larger stigmarian axes through upright growth.
