Contribution à l’étude de la bryoflore des hautes vallées du Verdon (Alpes-de-Haute-Provence) et du Var (Alpes-Maritimes)

Updating of the knowledge on the bryoflora of the upper valleys of the Verdon (Alpes-de-Haute-Provence) and Var (Alpes-Maritimes). Based on recent investigations and data from herbarium and literature, 165 species of mosses and 19 species of liverworts are known for the upper valley of the Verdon, 194 mosses and 34 liverworts for that of the Var. Two hundred and fifty nine bryophytes are found in both valleys considered as a whole, out of which the arctic and boreal element in a broad sense represents 48,7% of the total number of species. Encalypta affinis, Entodon concinnus, Schistidium dupretii and Seligeria calcarea are new for the bryoflora of the Alpes-de-Haute-Provence; Anoectangium sendtnerianum, Hypnum recurvatum, Pseudoleskeella tectorum, Pylaisia polyantha, Rhynchostegium murale, Riccardia palmata, Riccia breidleri, Riccia ciliifera and Scapania calcicola for the Alpes-Maritimes; Tortula virescens has never been reported from both departements.
