Document Summary

Touring the angiosperms: a fossil angiosperm: archaefructus, the most ancestral extant group: amborella, modern groups 4. Nymphaeales and austrobaileyales: chloranthaceae and ceratophyllum, magnoliidae, eudicots, and monocots. Coevolution of plants and pollinators: pollination versus fertilization, abiotic vs biotic, abiotic: water and wind, biotic: insects (beetles, bees, butterflies, moths, biotic: birds and bats 6. Plant goal achievement: trap flowers, a case study. 6 clades of angiosperms but most botanists recognize 8. The seed plants with archaefructus-sister taxa to modern flowering plants.
