Potonie (1898: 217-218) suggested that, in the late Paleozoic, scrambling and climbing pteridosperms and pteridophytes have played the same role angiospermous
lianas play in contemporary forest ecosystems and may thus have contributed significantly to the tropical character of the Late Carboniferous-Early Permian coal-swamp forests.
He asserted that the more specialized types of inflorescence tend to occur in angiospermous
trees (even in those of relatively primitive families, such as Platanaceae and Winteraceae), a fact that he attributes to adaptive selection.
