Pol len morphotype edmundi and its sig nif i cance for palaeoclimate re construc tions of the Neo gene. Geo log i cal Quar terly, 61 (2): 267-275, doi: 10.7306/gq.1344Pol len anal y sis has re vealed the pres ence of the edmundi morphotype in the Paleogene and Neo gene sed i ments of Cen tral Eu rope. Its spe cies, char ac ter ized by dif fer ent morphologies, are mainly as signed to two fam i lies of ex tant plants -the Araliaceae and the Mastixiaceae -and com pared to pol len of some gen era (Diplopanax and Mastixia from the Mastixiaceae, and Aralia, Fatsia and Schefflera from the Araliaceae). The most sig nif i cant ge nus for palaeoclimate re con struc tions is the ex tant Diplopanax, whose seeds, sim i larly as the seeds of other rep re sen ta tives of the Mastixiaceae, ap pear in the warm phases of the Neo gene. The type spe cies of Edmundipollis (E. edmundi) has been com pared to Diplopanax pol len. Based on sim i lar i ties with ex tant plants, the CA (Co ex is tence Ap proach) was de ter mined. The re sults in di cate a very warm and hu mid sub trop i cal cli mate (Cfa-Cwa) ac cord ing to the Köppen clas si fi ca tion.

Diversity patterns in microfloras recovered from Miocene brown coals of the lower Rhine Basin reveal distinct coupling of the structure of the peat‐forming vegetation and continental climate variability

“…In the studied profiles, it reaches highest values of 10% at the base of the Main Seam and in the top part of the Upper Seam. The morphogenus resembles pollen of plants belonging to the Araliaceae, Cornaceae and/or Mastixiaceae families (Stuchlik et al, 2014) and is not necessarily indicative for very warm conditions when identified at the generic level only (Slodkowska & Ziembińska‐Tworzydlo, 2017).…”

Polish Palaeobotany: 750 Million Years of Plant History as Revealed in a Century of Studies. Research on the Paleogene and Neogene (Tertiary)

“…She documented, using palynological methods, mega-scale glacitectonic structures in sediments from the vicinity of the Dylewskie Hills and confirmed such disturbances in the Muskau Arch (Kasiński & Słodkowska, 2017;Słodkowska & Gałązka, 2015). She demonstrated the importance of the Pollenites edmundi pollen morphotypes for palaeoclimatic considerations (Słodkowska & Ziembińska-Tworzydło, 2017). Barbara Słodkowska also conducted palynostratigraphic analyses of the Złoczew lignite deposit and in the Milicz region.…”

Paleovegetation and paleoclimate inferences of the early late Sarmatian palynoflora from the Gleisdorf Fm. at Gratkorn, Styria, Austria

“…"Remarks:" This fossil pollen type corresponds in exine sculpture, size, and aperture configuration to extant Mastixia pollen (Słodkowska and Ziembińska-Tworzydło, 2017). The form genera Cornaceaepollis Plate XXIV.…”

“…Light microscopy (LM) (1,4,7,10,13) and scanning electron microscopy (SEM) (2,3,5,6,8,9,11,12,14,15) and Edmundipollis are commonly used for fossil dispersed pollen with affinities to extant Mastixia (e.g. Stuchlik et al, 2014;Słodkowska and Ziembińska-Tworzydło, 2017). Extant Mastixia shows a south-east Asian and Indonesian distribution but had a wide northern hemispheric distribution during the Paleogene and early Neogene (Słodkowska and Ziembińska-Tworzydło, 2017).…”

“…Stuchlik et al, 2014;Słodkowska and Ziembińska-Tworzydło, 2017). Extant Mastixia shows a south-east Asian and Indonesian distribution but had a wide northern hemispheric distribution during the Paleogene and early Neogene (Słodkowska and Ziembińska-Tworzydło, 2017). Its species are insect-pollinated and thrive in well-drained lowland and upland evergreen forests up to 2600 m (VU5, VU6;eFloras, 2008).…”
