First Record of Fourteen Plant Species in the Western Izarene Massif (Prerif, Morocco)

As part of the continuity of our floristic work carried out between June 2021 and July 2024 in the Ouezzane region, we carried out a botanical study in the western part of the Izarene massif, which is part of the Prerif-Moyen Sebou region and corresponds to the Maroc atlantique nord-1 (Man-1) division. Field surveys of the territorial municipalities of Asjen and Brikcha and the Brikcha Site of Biological and Ecological Interest (SBEI) have enabled us to report for the first time the presence of fourteen species belonging to eleven families and fourteen genera, of which Lilium candidum is reported for the first time in Moroccan vascular flora. These are Biscutella pseudolyrata, Bolboschoenus glaucus, Crepis vesicaria subsp. stellata, Gagea fibrosa, Glinus lotoides, Hedera maroccana, Juniperus oxycedrus subsp. oxycedrus, Laurus nobilis, Quercus coccifera, Senecio glaucus subsp. coronopifolius, Silene sclerocarpa, Scorzonera hispanica subsp. hispanica and Thymbra capitata. Among these new species, we counted two endemics, one of which is strictly Moroccan (Biscutella pseudolyrata) and one that shares endemism between Morocco and Algeria (Hedera maroccana). Two species are rare and two are threatened with extinction. These additions represent an update of data concerning the flora of Man-1. Indeed, a synthesis of all the publications on the update of the vascular flora of Man-1 will be an important contribution to improving scientific knowledge on the distribution of new species in this division.
