Pliocene seeds of Passiflora subgenus Decaloba (Gray Fossil Site, Tennessee) and the impact of the fossil record on understanding the diversification and biogeography of Passiflora
Abstract Premise Passiflora is a diverse genus of ~570 extant species primarily distributed in the Americas, from the eastern United States to Argentina and Chile. Nevertheless, the known fossil record of Passiflora is small. To date, only two fossil seed species have been unequivocally assigned to...

In this contribution, rare sulcate seeds from Gray Fossil Site are described as a third fossil seed species of Passiflora .

They were compared to samples of sulcate seeds from six extant Passiflora species in supersection Decaloba . A broader survey of sulcate seeds produced by modern species in the subgenera Decaloba , Deidamioides , and Tryphostemmatoides was done using published illustrations and descriptions. Results The Gray Fossil Site seeds are described as Passiflora sulcatasperma , sp. nov., and assigned to subgenus Decaloba , supersection Decaloba . They are characterized by their small size, elliptical shape, ridged‐and‐sulcate sculpture, rugulose ridges, and thin palisade seed coat. Conclusions The two largest subgenera of Passiflora can be identified from Neogene fossils. Subgenus Decaloba is represented by two fossil seed species, P. bulgarica (Miocene, Bulgaria) and P. sulcatasperma (Pliocene, USA). Subgenus Passiflora is represented by fossil pollen (Miocene, Argentina and Brazil) and P . appalachiana seeds (Pliocene, USA). The distributions of fossil and modern species suggest that Passiflora may have used both North Atlantic and Antarctic routes to expand into Europe and the Asian‐Oceanian Paleotropics, respectively.
