“…While not all of these can be placed in a modern genus or clade within the subfamily, secure fossil evidence now indicates that two of the major subgenera of Passiflora had evolved and perhaps at least partially diversified by the Miocene. As shown in the results of this and previous studies (Palamarev, 1971; Hermsen, 2021), subgenus Decaloba is credibly represented in the fossil record by two seed species— Passiflora bulgarica (supersection Cieca ) from the middle Miocene of Bulgaria and P. sulcatasperma (supersection Decaloba ) from the early Pliocene of the eastern United States—representing two separate clades. Passiflora subgenus Passiflora is represented in the fossil record by both pollen and seeds.…”

“…While not all of these can be placed in a modern genus or clade within the subfamily, secure fossil evidence now indicates that two of the major subgenera of Passiflora had evolved and perhaps at least partially diversified by the Miocene. As shown in the results of this and previous studies (Palamarev, 1971;Hermsen, 2021) The distribution of fossils attributed to subgenus Passiflora (Figure 4) does not challenge assumptions about the subgenus based on its present-day diversity and distribution. Subgenus Passiflora is restricted to the Americas; its center of diversity is in northern South America, with species diversity progressively falling to the north and south (Ulmer and MacDougal, 2004).…”

“…Prior to the present study, only one fossil record had been definitively linked to Passiflora subgenus Decaloba : fossil seeds assigned to Passiflora bulgarica from the Miocene of Bulgaria (Palamarev, 1971; Palamarev et al, 1999, 2005; Hermsen, 2021). Passiflora bulgarica is similar to seeds of the extant species P. suberosa L. (Palamarev, 1971; Hermsen, 2021); Hermsen (2021) placed P. bulgarica in supersection Cieca on the basis of the diagnostic characteristics of seed shape and ornamentation pattern. Notably, Ivanov (2012) also reported Passiflora pollen from the middle Miocene of Bulgaria, although from a different locality than the P. bulgarica seeds.…”

“…The fossil record of subgenus Decaloba is slightly more confounding. The present center of diversity for subgenus Decaloba is a region spanning Mexico to northernmost South America (Colombia, Ecuador) and the West Indies (Ulmer and MacDougal, 2004); it includes one clade (supersection PASSIFLORA SUBGENUS DECALOBA FROM GRAY FOSSIL SITE Disemma) in Asia and Oceania (Ulmer and MacDougal, 2004;Krosnick et al, 2013a) and one fossil record of supersection Cieca in Europe (Figure 4;Palamarev, 1971;Hermsen, 2021). Explanations for how and when the ancient European distribution of Cieca developed are speculative; however, as several studies have pointed out, the North Atlantic Land Bridge is one likely connection between Old and New Worlds in the biogeographic history of Passiflora and/or Passifloroideae (Krosnick, 2006;Muschner et al, 2012;Krosnick et al, 2013a;Hermsen, 2021).…”

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 the genus. In this contribution, rare sulcate seeds from Gray Fossil Site are described as a third fossil seed species of Passiflora. Methods: Three partial seeds with sulcate sculpture from Gray Fossil Site, early Pliocene, Tennessee, USA, were examined, photographed, and measured. 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.

The present report aimed at providing information about the Fascination of Plants Day (FoPD) which is an initiative for popularization of plant science. FoPD was launched by the European Plant Science Organisation /EPSO/ to facilitate the understanding of plant science and to improve its impact and visibility. The FoPD initiative was set worldwide in 2012 for first time, as Bulgaria joined in 2015 and since then participates with events that bring plant science to the non- scientific public. The Agrobioinstitute of the Agricultural Academy as a coordinator for Bulgaria took the challenge to introduce FoPD among the academic society. In response, the scientific faculties of Sofia University, Shumen University, Agricultural University and other plant research institutions embraced the opportunity to reveal the charm of plants. Here is given an overview of the generally mastered strategies as we put accent on the activities undertaken in the Faculty of Biology of Sofia University where faculty members and students united with the Agrobioinstitute. Our mission is on one hand to convince more Bulgarian researchers to participate in the coming FoPDs, and on the other hand to attract more schoolteachers to bring pupils and future scientists to the organized events, as well as interested citizens, professionals, decision-makers and media.
