An annotated synonymic inventory of Italian Selaginella taxa, a practical key for their identification and their dot distribution maps are presented, as a result of our work on the Selaginellaceae account for the Flora Critica d’Italia.... more
The pteridological flora from Andalucía comprehends 30 genera, 68 species, 9 subspecies, 7 varieties, 2 forms and 7 hybrids. Ecology, phytosociology, vegetation stage and regional chorology is given for each specie.
There are few inventories of ferns and lycophytes of the Brazilian Amazon and most of them were made in areas of poor soils. The general species richness found in previous studies is low. This study presents an annotated list containing... more
Based on known data sets and maximum entropy distribution data of fern and lycopod species registered in the Yucatán Peninsula, track and parsimony analyses were undertaken to evaluate the contribution of these groups to the establishment... more
The importance of pteridophytes as biogeographic indicators in Ihe Iberian Peninsula andBaleares has been studied. Three analyses have been applied: m/t index, index of similarity with the adjacent regions and historical analyses.... more
