A taxonomic nightmare comes true: phylogeny and biogeography of glassworts (Salicornia L., Chenopodiaceae)
2007
In this study we analysed ETS sequence data of 164 accessions belonging to 31 taxa of Salicornia, a widespread, hygrohalophytic genus of succulent, annual herbs of Chenopodiaceae subfam. Salicornioideae, to investigate phylogenetic and biogeographical patterns and hypothesise about the processes that shaped them. Furthermore, our aim was to understand the reasons for the notorious taxonomic difficulties in Salicornia. Salicornia probably originated during the Miocene somewhere between the Mediterranean and Central Asia from within the perennial Sarcocornia and started to diversify during Late Pliocene/Early Pleistocene. The climatic deterioration and landscape-evolution caused by orogenetic…
Mangleticornia (Amaranthaceae: Salicornioideae) — a new sister for Salicornia from the Pacific coast of South America
2017
Mangleticornia ecuadorensis is a newly recognized monotypic genus from SW Ecuador and adjacent N Peru, where it had previously been identified as Salicornia fruticosa (Arthrocnemum fruticosum) or S. peruviana. It occurs on the coast adjacent to or in Equatorial-Pacific mangroves. Molecular phylogenetic evidence determines that this genus is distinct from and sister to Salicornia sensu lato, and is supported by morphological evidence. The genus is distinguished by a unique combination of characters that are otherwise rare in Salicornioideae: flowers without a visible perianth, anthers and stigmas exserted through pores in the fleshy cortical tissue of the segments, fruit included in the segm…
