Notes.

Murbeck (1921) described Celsia faurei based on collections done by A. Faure in western Algeria. The author in the protologue includes an explicit reference to the locality (Algeria, Oran: Between Imbert River and the railway embankment), with several years for the collection (1911, 1916, 1918, and 1921) and the herbarium where the original material are kept (LD). Benedí and Montserrat (1997) designated the A. Faure material at Herb. MPU as lectotype and that preserved at Herb. LD as isolectotype. However, the material kept at Herb. MPU cannot be considered as original material since the herbarium that housed the type specimens is indicated in the protologue. The lectotype designation by Benedí and Montserrat (1997) is obviously flawed and cannot be considered here because it is in conflict with the protologue according to Art. 9.19 of the ICN ( Turland et al. 2018). Pertaining to the original material specification provided in the protologue, five specimens at Herb. LD were traced (LD1223785, LD1220485, LD1223485, LD1223665, and LD1244709) on which are stamped “Type”. In the absence of indicating a single specimen as the holotype, all of the specimens cited in the protologue are to be treated as syntypes (Art. 9.6 of ICN, Turland et al. 2018). The sheet LD1244709 is chosen here as the lectotype, because it shows the best quality of preservation of the important diagnostic features of the taxon. However, the other remaining specimens (LD1223485, LD1223785, LD1223665, LD1220485) traced are referred to as original material following the Art. 9.4 of ICN ( Turland et al. 2018).
