| Editorial Comments 1 | Correspondence 1 indicates that according to Verloove & Sânchez Gullón [Verloove F. & Sânchez Gullón E.: A taxonomic revision of non-native Cenchrus s.str. (Paniceae, Poaceae) in the Mediterranean area. Willdenowia 42: 67 – 75. June 2012], if considered conspecific with Cenchrus spinifex Cav. (1799), plants treated as Cenchrus incertus M. A. Curtis (1835) in this Index and in the eFlora should be called Cenchrus spinifex Cav., based on priority. [According to Verloove & Sânchez Gullón, "The application of the binomial Cenchrus spinifex is not uncontested. In addition to the aforementioned taxonomic difficulties there is still a nomenclatural problem. DeLisle (1963) already evoked that the correct name for C. incertus might be C. spinifex, which, indeed, antedates the former (1837 [sic] versus 1799). As he had not been able to study the holotype of C. spinifex and the correctness of the isotype label had not been verified, he rejected this binomial. In the recent treatment of Cenchrus for North America (Stieber & Wipff 2003) the plants here concerned are referred to as C. spinifex but it is unclear whether or not these authors had effectively resolved the nomenclatural problem. Moreover, C. incertus is not even mentioned as a synonym by these authors. In the recent catalogue of New World grasses (Zuloaga & al. 2003), C. incertus is upheld and it is stated that "... if C. spinifex turns out to be conspecific, a conservation proposal will be considered". According to Ward (2010), C. spinifex is an unidentifiable name that should be rejected. Symon (2010), who examined a digital image of the holotype, on the contrary confirms that both are conspecific and hence C. spinifex should finally be accepted as the correct name for this species. Joseph Wipff recently also investigated the type of the latter name and states that it definitely refers to the taxon traditionally called C. incertus (pers. comm. March 2012). Therefore, Current Status of Cenchrus incertus M. A. Curtis changed to Jepson Flora Project-2a, from Jepson Flora Project-2 previously in this Index, 18 Aug 2020.] | |||||
