que09 | J. Pallas prefers to separate the southern temperate (Quercion robori-pyrenaicae) from the submediterranean (Quercion pyrenaicae s.str.) forests at the level of alliances (Pallas in Bohn et al. 2003: 250−253). We follow Rivas-Martínez et al. (2001) who considered these two units only at the suballiance level. (W. Willner).
