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.
Lauraceae), "winteroids" (Winteraceae, Illiciaceae), and eudicots (Eupteleaceae,
Platanaceae, Hamamelidaceae, Tetracentraceae) are known (Page, 1981; Wheeler & Baas, 1991), but the precise relationships of many of these fossils and their evolutionary implications remain unknown.
