Then, they were dried in the shade for about ten days. The plant species were botanically identified at the floristic laboratory of the Scientific Institute of Rabat. The voucher specimens of the 3 species were preserved in an herbarium at INRA-Agadir and labelled as TZ-2017, SO-2017, and MS-2017, respectively.
