Quelques bryophytes intéressantes du massif de l'Adrar (Mauritanie)

The bryophyte flora of Mauritania is poorly known, only five species of bryophytes having been cited previously. Based on field collections and diaspore bank studies, seven bryophyte species have been identified, two of which were reported previously for the country (Gymnostomiella monodii and Riccia cavernosa). Five are new to Mauritania (Barbula indica, Eucladium verticillatum, Philonotis hastata, Splachnobryum obtusum and Leptophascum leptophyllum); the last one is also a new record to Northern Africa.
