Original diagnosis/description

Pollen organ bearing loosely arranged microsporophylls radiating from a central core. Microsporophyll ellipsoidal to barrel-shaped with a flattened or slightly depressed peltate apical head; each microsporophyll with about ten narrow sporangia in a radial arrangement. Pollen of Eucommiidites-type with long main (distal) colpus flanked by two lateral colpi in almost equatorial position; tectum psilate, occasionally with small puncta proximally. Tectum thick, infratectal layer and foot layer thin. Pollen length (L) to width (W) ratio about 3:2.


The specific epithet portucalensis is derived from Portugal, where the fossils were collected.
