Serialis crassitesta E.M.FRIIS, P.R.CRANE et K.R.PEDERSEN, 2019

Text-fig. 17b

Description and remarks. The material includes several fruits with permanently adhering seeds that are assignable to Serialis crassitesta ( Text-fig. 17b ).

Affinity and other occurrences. Conclusions on the relationships of Serialis crassitesta are similar to those on Serialis communis (see above). Serialis crassitesta is common in the Famalicão mesofossil flora with about 375 specimens, but less common than S. communis . Serialis crassitesta is also common in the Vale de Água mesofossil flora ( Friis et al. 2019c) and is present in the Chicalhão (“Fruits with co-adhering seeds in row type 2”; Mendes et al. 2014) and Nossa Senhora da Luz mesofossil floras (“Seeds in row”; Mendes and Friis 2018).
