“…There are many reports of fossil leaves assigned to Menispermites Lesq. dating back to the mid-Cretaceous (Lesquereux, 1874;Golovneva et al, 2015), but not all can be accepted as reliable occurrences of the family (Forman, 1986;Doria et al, 2008). A handful of species are known from fossil woods (Vozenin-Serra et al, 1989;Bonde, 1997;Poole and Wilkinson, 2000); however, the oldest of these, Anamirta pfeifferi Bonde from the Paleocene of India, is in need of re-evaluation and may not be Menispermaceae (Bonde, 1997;Jacques and De Franceschi, 2007;Smith et al, 2013;Wheeler et al, 2017).…”

Our findings highlight the importance of West Gondwana in the evolution of Menispermaceae during the Paleogene. Currently, the fossil record does not discern between a Laurasian or Gondwanan origin; however, it does demonstrate that Menispermaceae grew well outside the tropics by the early Paleocene. The endocarps' affinity with Cissampelideae suggests that diversification of the family was well underway by the earliest Paleocene.

“…As Menispermaceae leaves generally gather homoplastic characteristics (Ortiz et al, 2007;Hoot et al, 2009), and the leaves from Jianglang did not contain all the characteristics usually important for diagnosis (e.g., cuticle), we assigned all leaves to the fossil genus Menispermites. We adopt a broad concept of Menispermites accommodating all fossil leaves of probable menispermaceous affinity with basal actinodromous primary venation and a generally cordate to truncate base (Golovneva et al, 2015;Jud et al, 2018). The leaves described here differ from the fossil genus Wilkinsoniphyllum Jud, Gandolfo, Iglesias, & Wilf (Jud et al, 2018) Hill, 1989).…”

Menispermaceae are a pantropical and temperate family with an extensive fossil record during the Paleogene period, especially in North America and Europe, but with much less evidence from Asia. The latest fossil evidence indicates a succession of tropical to subtropical flora on the central Tibetan Plateau during the Paleogene. However, the biogeographic histories of these floras are still unresolved. Here, we report on endocarps and leaves of Menispermaceae from the Middle Eocene of Jianglang village, Bangor County, central Tibetan Plateau. The endocarps belong to two genera: Stephania, which is characterized by a horseshoe-shaped endocarp and with one lateral crest ornamented by spiny to rectangular ribs, and a condyle area; and Cissampelos (s.l.), which has two characteristic lateral ridges and a conspicuous external condyle. Associated leaves belong to the genus Menispermites, and are characterized by actinodromous primary venation, brochidodromous secondary veins, entire margins, and the presence of marginal secondary veins. The biogeographic history of Menispermaceae is complex, but evidence from these new fossils indicates an early diversification of the group in Asia, probably in response to the warming climate during the Eocene. The Jianglang flora appears to be part of a boreotropical flora, connecting Asia with North American and European floras during the Middle Eocene. The modern distribution of menispermaceous taxa found in Jianglang, as well as other families represented in the Jianglang flora, show that a tropical to subtropical climate occurred during the Eocene in central Tibet.
