Molecular phylogenetic data and seed coat anatomy resolve the generic position of some critical Chenopodioideae (Chenopodiaceae - Amaranthaceae) with reduced perianth segments.

ABSTRACT: The former Chenopodiumsubgen.Blitum and the genus Monolepis (Chenopodioideae) are characterised in part by a reduced (0-4) number of perianth segments. According to recent molecular phylogenetic studies, these groups belong to the reinstated genera Blitum incl. Monolepis (tribe Anserineae) and Oxybasis (tribe Chenopodieae). However, key taxa such as C.antarcticum, C.exsuccum, C.litwinowii, C.foliosumsubsp.montanum and Monolepisspathulata were not included and so their phylogenetic position within the Chenopodioideae remained equivocal. These species and additional samples of Blitumasiaticum and B.nuttallianum were incorporated into an expanded phylogenetic study based on nrDNA (ITS region) and cpDNA (trnL-trnF and
