D.  aHypotheses for the evolution of dioecy in seed plants.h[electronic resource]  c1990  aIn the hypotheses reviewed, many of the selective mechanisms invoked have been suggested and supported by phylogenetic correlations. The validity of these correlations are discussed in the light of empirical data. The factors correlated with dioecy include sex allocation, avoidance of selfing, various morphological characters (woodiness, fleshy fruits, inconspicuous flowers), floral syndrome and floristic patterns.  adioecy  aevolution  aphylogeny  asexual reproduction1 aBRUNET, J.  tTreeegv. 5, n.1, p. 11-16, 1990.
