Self-isolation and insect pollination in the primitive angiosperms: New evaluations of older hypotheses

  title={Self-isolation and insect pollination in the primitive angiosperms: New evaluations of older hypotheses},
  author={Peter Bernhardt and Leonard B. Thien},
  journal={Plant Systematics and Evolution},
A review of the literature, compiled over the past 40 years suggests new directions for theories discussing the evolution of reproductive isolation and entomophily in angiosperms. Data on breeding systems suggests that the protoangiosperms may have developed gametophytic self-incompatibility. Protogyny is probably ancestral to protandry and herkogamy. Although the proto-flowers were bisexual wide variation in the number of sexual organs within proto-flowers probably led to labile sexuality and… CONTINUE READING
