The 250,000 to 400,000 species of flowering plants outnumber all other ground plants combined, and are the dominant vegetation in most terrestrial ecosystems. There is fossil evidence that flowering plants diversified rapidly in the Early Cretaceous, from 130 to 90 Ma, and that their rise was associated with that of pollinating insects. Among modern flowering plants Magnolias are thought to be close to the common ancestor of the group. However paleontologists have not succeeded in identifying the earliest stages in the evolution of flowering plants.

Famous quotes containing the words flowering and/or plants:

    “we, outlaws on God’s property,
    Fling out imagination beyond the skies,
    Wishing a tangible good from the unknown.
    And likewise death will drive us from the scene
    With the great flowering world unbroken yet,
    Which we held in idea, a little handful.”
    —Richard Eberhart (b. 1904)

    “What I did not yet know so intensely was the hatred of the white American for the black, a hatred so deep that I wonder if every white man in this country, when he plants a tree, doesn’t see Negroes hanging from its branches.”
    —Jean Genet (1910–1986)
