Fig. 6. Scenario of Osmundea biogeography using frame from Scotese animation (www.scotese.com/) at 100 Ma. South America and Africa are starting to move apart. Hypothetical ancestors (A) of widespread and diverse Osmundea Fora along Tethyan shores of which Osmundea caspica (A.D.Zinova & Zaberzhinskaya) comb. nov. (b) is almost certainly a relic. Since 100 Ma, Osmundea has colonized the Atlantic Ocean (c, e). Brazilian O. sanctarum M.T.Fujii & Cord.-Mar. (c) is likely a relic of the lineage at the origin of the clade that entered the Pacifc (d) and colonized the Americas.
