Celsia laciniata brvipes = Celsia laciniata Poir. var. brvipes Barratte, in Bonnet & Barratte Cat. Rais. Pl. Vasc. Tunisie: 311. 1896. Type: not designated. Notes. When he described this species, Battandier (in Battandier and Trabut 1889 ) did not specify in which herbarium the type had been deposited. After an in-depth search, we found three sheets at Herb. MPU bearing labels handwritten by Battandier and rewritten by Dr. R. Maire, on which he noted "Type" . The first sheet (MPU007789) bore a label reading "Oued Biskra, Avril 1895, [ Battandier's signature]", the second one (MP007790) bore a label reading " Celsia ballii Batt. / El Kantara / Avril 1895 / leg. J. A. Battandier / [ Battandier's signature]/" and the last one (MPU009629) bore a label reading " Celsia ballii Batt / C. Ain-Oumach , montagne / J. A. Battandier ". However, these sheets presented two inaccuracies when compared with the protologue: (1) specimens MPU007789 and MP007790 were collected after the protologue was published, and (2) the collection locality indicated on the label of sheet MPU009629 did not match with the one cited in the protologue. Therefore, the "type" notation by Maire on Celsia ballii sheets was mistaken. Since no specimen from the original gathering in any institution was traced, a neotype should be designated according to Arts 9.8 of the ICN ( Turland et al. 2018 ). We selected sheet MPU007789 stored at Herb. MPU as a neotype since it was collected and identified by Battandier and display all the morphological features described in the protologue.
