The fasciculate zone had large cells with central nucleus and visible nucleolus, large amount of mitochondria and cytoplasm filled with enormous amount of lipid vesicles, and it was the area where the greatest amount of these vesicles were noted when compared to the other two cortical zones.
In this region, a large amount of lipid vesicles were found, but in a smaller amount than that found in the fasciculate zone.
Despite only being collected in Serra de Monfurado (Alentejano district), with penatilobate leafs and the abaxial surface laden with stellate and fasciculate trichomes, and both surfaces tomentose to velvety, its distribution range should be much wider, being cited by Costa & al.

Two types of trichomes are present on the abaxial surface, simple and fasciculate stipitate.
On the abaxial surface there are four types of trichomes: stellate trichomes, with 8-10 rays about 165-169 [micro]m long, fused stellate trichomes (with 8-10 arms), fasciculate stipitate with 6-7 rays (109-200 [micro]m), and simple trichomes (53 [micro]m).
alba, is characterized by anthelate or fasciculate inflorescences, hypogynous bristles, and deeply bifid styles.
Polycephalae are capitate, and those of Pseudocapitatae are fasciculate.

The unusual fasciculate hairs may also be synapomorphic.
Indumentum of fasciculate branched and small glandular hairs.
Moreover, no fasciculate
stamens are known in the Laurales, and the relative (vascular) independence of the nectarial appendages is due to their late appearance in ontogeny (Endress, 1980).
