– lyg02 The names Thero-Brachypodietea, Thero-Brachypodietalia and Thero-Brachypodion are to be considered nomina ambigua since they can no longer be used without ambiguity according to their nomenclature type, that is, only for perennial Mediterranean grasslands (pseudo-steppes) with therophytes, as they are often at variance with their nomenclature type for annual plant communities (e.g. Theurillat et al. 1995). Inasmuch, they have been considered repeatedly as nomina ambigua, for instance by Rivas-Martínez et al. (1999, 2001, 2002a, 2011; Bardat et al. 2004). (J.-P. Theurillat, L. Mucina).
