Abstract

Further Concepts in Ecological Wood Anatomy, with Comments on Recent Work in Wood Anatomy and Evolution

Highlights

  • In recent years, work in wood evolution has featured an interesting mixture of comparative and experimental work, a consideration of anatomy, ultrastructure, and ecology, with modes of presentation stressing theoretical, quantitative, and graphic elements

  • A variety of topics have been selected for consideration: 1. Interpretation of the different types of growth rings as ecologically adaptive devices, together with a classification of growth rings on the basis of variations far known

  • In addition to predominant phylesis toward colder and drier by angiosperm groups and in addition to inability to form structures for which genetic information has been lost such as scalariform perforation plates, Baileyan "irreversibility" connotes simultaneous evolutionary shift of numerous features within the secondary xylem, and of complex correlation of a functional sort among these features, the complexity so great that reversion no longer becomes possible to any statistically appreciable degree
