CRAWFORD, DANIEL J. Department of Plant Biology, The Ohio State University, Columbus, OH, 43210. - G. Ledyard Stebbins and plant evolutionary biology in the next millennium: Introduction to the Symposium.
G. L. Stebbins is widely regarded as the foremost plant evolutionary
biologist of this century. In addition to being one of the four major
figures in forging the evolutionary synthesis, he has influenced
prevailing thought on many aspects of plant evolution and on the
origin and radiation of the angiosperms. The speakers in this
symposium will discuss new data, methods of data analysis and theory
from the perspective of Stebbinsian views on the topics of species and
speciation, polyploidy, hybridization and the origin and
diversification of the angiosperms. The speakers will present their
visions of research necessary into next millennium to answer
longstanding questions in plant evolution and phylogeny.
Key words: angiosperm radiation, hybridization, polyploidy, speciation
