Fig. 5. Fruit of Sagaria cilentana. A, fruit in Fig. 4a showing the presumed line of dehiscence (upper arrow) and fine longitudinal striations on pedicel (lower arrow); scale
bar ¼ 1 mm. B, counterpart of A, showing the presumed line of dehiscence (arrow); scale bar ¼ 1 mm.
Hyrcantha (Krassilov et al., 1983; Leng and Friis, 2003; Dilcher et al.,
2007), Achaenocarpites, and Ternicarpites (Krassilov and Volynets,
2008) suggests that early radiation of ranunculoid eudicots was well
underway during Early Cretaceous time.
