Notes.

This species was described by Ball (1875: 172) from material gathered by himself, J.D. Hooker, and G. Maw during their botanical expedition in Morocco in 1871 ( Hooker and Ball 1878; Stafleu and Cowan 1976-1988). Murbeck (1925) indicated that the original material is stored at Herbs K and B. During our research, we have traced five specimens kept at Herb. K and bearing K barcodes as follows: K000410853, K000410855, K000410856, K000410857, K000410858. However, no relevant specimens could be traced at Herb. B, so we have some reasons to think that this material was destroyed during the bombing raid at Berlin in 1943 (Hiepko, 1987). In all the specimens found the collecting localities on labels match those mentioned in the protologue and material morphologically agrees with the original description. Since no holotype was indicated, they are all syntypes according to Art. 9.6 of the ICN ( Turland et al. 2018). Hence, among all the original material kept at Herb. K, the specimen bearing the K barcode K000410855 is selected here as the lectotype.
