PFN000461 (for new genus).
E t y m o l o g y. In honor of the Hungarian palynologist Ferenc Góczan in recognition of his important contribution to Cretaceous palynology.
D i a g n o s i s. Stamens short, broad, dithecate and tetrasporangiate. Inner surface of anther wall with densely arranged orbicules. Orbicules small, spherical with microechinate surface. Pollen small, oblate, circular to elliptical in equatorial outline, monocolpate with a simple colpus. Exine tectate with a smooth to slightly rugulate surface. Supratectal ornamentation microechinate, composed of solitary microechinae. Infratectal layer granular. Colpus margin irregular, distinct.
C o m m e n t s o n t h e g e n u s. Pollen grains of Goczania are very similar to the pollen associated with fruits of Appomattoxia and Appofructus . In the original discussion of Appomattoxia ( Friis et al. 1995) we noted the similarity of the pollen associated with Appomattoxia to dispersed pollen grains of Transitoripollis GÓCZAN et JUHÁSZ ( Góczan and Juhász 1984) and Tucanopollis REGALI ( Regali 1989). However, Tucanopollis is clearly distinguished from the pollen grains of Goczania by its ring-shaped aperture and thicker pollen wall. The type species of Transitoripollis, T. anulisulcatus GÓCZAN et JUHÁSZ , also differs from Goczania - type grains in having an annular aperture ( Góczán and Juhász 1984). SEM of the exine also shows that grains of Transitoripollis have microechinae that are often merged together in groups, while in Goczania microechinae on the tectum surface are solitary. Dispersed pollen grains with solitary microechinae and a rugulate surface similar to Goczania rugosa have been described from the Hauterivian- Aptian of southern England and assigned to the informal biorecord Hauterivian- cactisulcus and CfB Hauteriviancactisulcus (Hughes 1994). Grains described as CfA Barremian- ring (Hughes 1994) may also be related, but have a round, rather than elliptical aperture. Similar grains are also reported from the early Aptian-early Albian of Egypt as Fulltec-Solid ( Penny 1991).
