Poion violaceae Horvat et al. 1937
tri14 | In the protologue of this alliance Horvat et al. (1937: 174, see footnote) suggested that this alliance was earlier described as the 'Festuceto-Poion violaceae' however these authors suggested a simplified name − the 'Poion violaceae'. However, the Festuco-Poion violaceae was invalidly described in Horvat (1937) and therefore the introduction of a nomen novum (ICPN art. 29) does not apply in this case. On the other hand, the Poion violaceae was clearly validly described by Horvat et al. (1937) since the only association (Festucetum validae Horvat et al. 1937) classified within the this alliance was a syntaxonomic concept carrying a valid name. (L. Mucina).
