100 years of Baileyan Trends –Wood Evolution, Function and Future.

We propose a symposium to commemorate the centennial anniversary of the publication of Bailey and Tupper’s classical paper “Size variation in tracheary cells: I. A comparison between the secondary xylems of vascular cryptograms, gymnosperms and angiosperms”. Figure 6 from this paper, which illustrates evolutionary trends from tracheids to fibers on one side and from tracheids to vessels on the other, remains one of the most widely used images in botany. Bailey’s insights into xylem evolution were derived primarily from comparative studies of lengths of tracheary elements across a wide range of vascular plants. In keeping with Bailey’s themes, we have chosen to focus on the context of his work and on evolution of xylem. We will present current thoughts on the evolutionary trends in secondary xylem extending from fossils through the most recent APG classification, and then move to ecophysiological context driving wood evolution, the evolution of pit structure and other functional xylem traits. We will include recent work on secondary evolution of woodiness and will conclude with a perspective that focuses on possible directions for the future of wood anatomy in the Anthropocene. Finally, if the symposium is approved, Sherwin Carlquist will be invited as a guest of honor. Relevance:
