Bituminaria antiatlantica Brullo, C. Brullo, Cambria, Cristaudo & Giusso, sp. nov.
Bituminaria bituminosa (L.) C.H. Stirt. affinis, sed habitu suffruticoso, ramis lignosis, foliolis glabris vel sparsim pilosis, subrotundatis vel ovatis, max. 35 mm longis, petiolis usque ad 6 cm longis, inflorescentia laxa, saepe subspicata, 1,5-2 cm longa, 3-10-flora, calice 12-13.5 mm longo, corolla pallida.
Distribution and ecology: Bituminaria antiatlantica is a rare and localized species, currently known only from Mount Tachilla and Djebel Imzi in the Anti-Atlas Mountains in southern Morocco, (Fig. 3). It grows between 300 and 1500 m of altitude, on steep, north-facing slopes, chiefly constituted of Precambrian quartzite. From the bioclimatic viewpoint, this area falls within the infra- and the thermo-mediterranean type, with semiarid to subhumid ombrotype (Benabid and Cuzin, 1997). ...
Etymology: The specific epithet refers to the Anti-Atlas range, where the species occurs.
