COMMENT

Riella battandieri and R. reuteri were considered by Jelenc (1957) synonyms of R. notarisii (Mont.) Mont. That was also the criterion of Schumacker et al. (2005) and followed by Ros et al. (2007a). Although both species were listed by Söderström et al. (2016) and Hodgetts et al. (2020) as accepted species, these works also stated that their taxonomical distinction is questioned and that they belong to Riella notarisii complex with poorly defined taxonomic boundaries, as did Segarra-Maragues et al. (2022). Jelenc (1957) stated that the area where R. notarisii had been found in Algeria (sub R. battandieri ) had been cultivated at that time and it should be supposedly taken that the species had disappeared. The only reference to R. reuteri in Algeria was done by Allorge (1932), in a map of his Pflanzenareale series, but no previous report seems to have been published on this name.
