PFN000495 (for new genus).

E t y m o l o g y. In honor of the Russian palaeobotanist Valentina A. Samylina in recognition of her contribution to the study of Cretaceous angiosperms.

D i a g n o s i s. Pollen of medium size, prolate, tricolpate. Colpi long, reaching almost to the poles, irregular in organization, sometimes branched. Exine columellate, tectate-punctate. Columellae short. Colpus margin distinct. Colpus membrane coarsely verrucate. Orbicules small, spherical, with a finely granular surface.

C o m m e n t s o n t h e g e n u s. Samylinaea is characterized by the presence of irregular folds or openings between the regular colpi, which sometimes create a branched appearance. Such irregularity is not common among eudicot angiosperms, but also occurs in the pollen of Mcdougallia described above.
