Current nomenclature and systematics of Capsella Medik. with lectotypifications:towards solving the puzzle

The taxonomic history of Capsella Medik., one the genera with highest phenotypic plasticity, and thus synonym number relative to recognized species number, was reviewed. current systematics genus discussed exact taxa determined. In light molecular nomenclatural data, it decided that represented around world by five hybrid. Considering studies have been conducted over 30 years concluded this are typical examples concept cryptic species. classification nomenclature such genetically different, morphologically similar should be most discussion topics modern systematic science. is best examine situation; hence, feature herein. It C. thracica × abortiva conspecific correct naming (pro hybr.). Lectotype assignments were performed for names 5 taxa, mainly rubella, abortiva, thracica. Also, missing type specimen Turkish endemic lycia found, lectotype assigned determined a bursa-pastoris. Various errors in sample references, especially holotype grandiflora, corrected.
