Hypercalcified sponges from the Upper Triassic (Norian-Rhaetian) reefs of Sicily
2015
The sponge-dominated Upper Triassic (Norian-Rhaetian) reefs of Sicily yielded the most abundant hypercalcified sponge taxa compared with other time equivalent reefs in the world. Chambered sponges (“Sphinctozoa”) are the most abundant group among the hypercalcified sponges. All together almost 150 species of hypercalcified sponges (including sphinctozoans, inozoans, chaetetids, disjectoporids and spongiomorphids) were recognized in the Norian-Rhaetian reefs occurring in different localities in Sicily. 93 species (30 new, 28 as sp. indet.) of sphinctozoans, belonging to 18 families (2 new: Polytubithalamiidae, Globucatenulaiidae) and 35 genera (4 new: Globucatenula, Polytubithalamia, Rostros…
Brassica trichocarpa (Brassicaceae), a new species from Sicily
2013
A new species of Brassica from Sicily, namely B. trichocarpa, is described and illustrated. This suffrutex was found on a calcareous peak of a mount near Palermo, where it is represented by a single population occupying a really small surface. It is well differentiated from the other perennial species belonging to B. sect. Brassica mainly in having hairy ovary and very short, thickened, hairy, not torulose fruits. Its relationships and taxonomical position within this group are examined too. An analytical key of the current taxa belonging to the genus Brassica sect. Brassica is also provided.
