A new name for a hybrid Salicornia (Amaranthaceae)

Abstract

In a radical new classification of Salicornia in Europe, Kadereit et al. (2012) placed the four British diploids (S. europaea L., S. ramosissima Woods, S. obscura P.W. Ball & Tutin and S. pusilla Woods) in a single species, S. europaea, the first three segregates in one and the fourth in a second subspecies (subspp. europaea and disarticulata (Moss) Lambinon& Vanderp. respectively). Inaddition, hybridsbetween these two subspecies (i.e. in the British context, between S. pusilla and S. ramosissima) were described as a nothosubspecies of S. europaea. These hybrids have been known in Britain for a century (Marshall, 1915), and were provided with three binomials (S. |marshallii, S. |townsendii, S. |bartonii, all nomina nuda) by Druce (1929), the epithet of the first being taken up by Kadereit et al. (2012). If S. pusilla and S. ramosissima are to be retained at species level, as in the forthcoming Hybrid Flora of the British Isles (Stace et al., 2015), the hybrid needs a new combination as a nothospecies:
