Abstract

Chenopodium album s. l. is one of the most taxonomically difficult groups of taxa in the genus Chenopodium s. s. due to its high phenotypic variability and possible ancient and current hybridization which led to numerous nomenclatural problems and misapplication of names. Proper application of many names in Chenopodium (especially taxa described in the 18–19th centuries) still remains uncertain. As currently accepted in recent publications, several subspecies can be considered under C. album for the European flora, i.e C. album subsp. album, C. album subsp. pedunculare (Bertol.) Arcang., and C. album subsp. borbasii (Murr) Soó. Beroloni’s C. pedunculare (basionym of C. album subsp. pedunculare) appears still poorly understood taxonomically. The present contribution is based on field surveys, analyses of the relevant literature (protologues included), and examination of specimens preserved in several herbaria. The name C. pedunculare was lectotypified by Dvořák (1984) on a specimen deposited at BOLO. Based on morphology and chorology considerations, that taxon can be recognizes at species rank. For nomenclatural purposes, the names C. concatenatum Thuillier (and sensu Aellen), C. glomerulosum, and the Linnaean C. viride are discussed. C. concatenatum is here lectotypified on a specimen deposited at G. The names C. glomerulosum Rchb. and C. viride L. remain taxonomically unresolved. Morphological comparison of original specimens of C. pedunculare and C. lanceolatum Muehl. ex. Willd. demonstrated that, despite their superficial similarity, it is not advisable to synonymize these taxa.
