Distribution of Cytisus absinthioides Janka. Notes on taxonomy. Cytisus absinthioides strikingly differs from any other species of the C. austriacus group by its habit, resembling some plants of Artemisia due to its tall branched stems with regularly developed sterile branches in leaf axils and dense appressed sericeous pubescence on its leaves and calyces. Its calyces and pods are distinctly small ( Janka 1872 ). Some recent interpretations ( Cristofolini 1991 ) placed C. absinthioides to the synonymy of C. eriocarpus , which was treated as a broadly defined and variable species. This placement is not justified because C. eriocarpus clearly differs in its habit, leaf shape, subpatent pubescence and longer calyces. Pifko and Barina (2016) and Barina et al. (2018) reported the presence of C. eriocarpus in Albania, but their description matches C. absinthioides . The earlier records of C. eriocarpus in Greece ( Strid 1986 ) employed the same taxonomic concept and should also belong to the same species ( Kuzmanov 1976 ; Micevski 2001 ; Assyov and Petrova 2012 ).
