Fig. 5 in Early evolution of Coriariaceae (Cucurbitales) in light of a new early Campanian (ca. 82 Mya) pollen record from Antarctica

Fig. 5. Fossil and extant representatives of Coriariaceae observed with light microscopy. A, B, D, E, G & H, Pollen of Coriaripites goodii sp. nov. from the late Cretaceous of Antarctica (blue frames). A & B, Pollen on slide BA-Pal. ex CIRGEO Palin 611b: C54-1; D & E, Pollen on slide BA-Pal. ex CIRGEO Palin 963b: R31-1; G & H, Pollen on slide BA-Pal. ex CIRGEO Palin 698b: E30-2. All grains in polar view. A & B, Note the well-defined fastigium and short colpi with pointed ends (arrowheads); D & E, Note stratified thin exine and short colpi (arrowheads); G & H, Pollen with four apertures; note clearly defined fastigium and very short colpi (arrowheads). C, F & I, Pollen of extant species for comparison (magenta frames). C, Extant Coriaria plumosa; F, Extant Coriaria ruscifolia; I, Extant Coriaria myrtifolia, pollen with four apertures and clearly defined fastigium (arrowhead). — Scale bars = 5 μm.
