Isatis tinctoria
A mere remnant of their former glory the cedar forests are still impressive covering large areas of the Middle Atlas. The dominant plant "Cedrus libani var. atlantica" is peculiar to this zone along with "Juniperus foetidissima" and a multitude of low plants: "Iberis odorata", "I. ciliata", "I. taurica", "Centaurea" spp., "Prunus amygdalus", "P. persica", "P. institia", "P. longipes", "Pyrus communis", "Malus domestica", "Crataegus oxyacantha", "Sisymbrium" spp., "Lunaria biennis", "Capparis spinosa", "Raphanus raphanistrum", "Isatis tinctoria" continue. There is a total lack of the oak-dominated maquis of the Mediterranean zone and the lower limit of the zone of the Cedar is demonstrated by the lack of "Berberis cretica".
