Nomenclatural notes — The protologue of Panicum trichopus mentions a single collection: Kotschy 74. Since Hochstetter worked at Tubbingen, which holds a duplicate, that material was chosen as the lectotype.

The protologue of Panicum mosambicense does not provide any information about the type, apart from its origin being Mozambique. Clayton & Renvoize (1982) denoted the isotype as being Carvalho 19 at K, unfortunately without any explana- tion, but which is, according to ICN Art. 9.10 ( Turland et al. 2018), to be regarded as a lectotypification of the gathering. Subsequently, Sosef (2016) denoted the duplicate at W, where Hackel worked, as the lectotype. Although its label suggests it is a duplicate from COI, no specimen could be traced there. The protologue of Panicum trichopus var. chiovendae mentions three specimens collected by L. Senni , which are to be regarded as syntypes. Since we were unable to study any of these, we refrain from designating a lectotype.

The protologue of Urochloa engleri cites two syntypes, Engler 6406 and Diels 2908. The first was indicated by Clayton & Renvoize (1982) as the ‘holotype’, to be regarded as a lectotypification (ICN, Art. 9.10; Turland et al. 2018).
