Link to protologue:
Comment: when Cirillo published the genus Imperata (in Pl. rar. neapol. 2: 26. 1792) he cited Lagurus cylindricus L. in its synonymy, thus Räuschel’s use of the generic name Imperata together with the Linnaean species epithet provides sufficient indirect link to the basionym Lagurus cylindricus, and this can be considered a validly published new combination (Melbourne ICN Art. 38.13 & 38.14)
