Dva vida roda Galeopsis L., G. tetrahit L. i G. bifida Boenn. (sem. Lamiaceae), trudno razlichimy mezhdu soboi, chasto opredelyayutsya neverno i nekotorymi sistematikami schitayutsya odnim vidom. Morfologicheskie diagnosticheski znachimye priznaki ikh variabel'ny i otchasti perekryvayutsya. Dlya vyyasneniya vidovoi samostoyatel'nosti, a takzhe utochneniya diagnosticheskikh priznakov G. tetrahit i G. bifida provedeno issledovanie s ispol'zovaniem ISSR- i RAPD-markerov. Vsego polucheno 57 ISSR- i 28 RAPD-fragmentov, pozvolivshikh chetko razdelit' izuchennye obraztsy na dve gruppy. Analiz molekulyarnykh dannykh po metodu ob"edineniya sosedei (neighbour-joining) razdelil obraztsy na dve klady tochno takim zhe obrazom, kak i analiz tekh zhe obraztsov po 20 morfologicheskim priznakam s pomoshch'yu metoda blizhaishego soseda (single linkage). Eti rezul'taty svidetel'stvuyut v pol'zu samostoyatel'nosti G. tetrahit i G. bifida. Morfologicheskie priznaki okazyvayutsya bolee variabel'nymi po sravneniyu s molekulyarnymi, khotya ispol'zovanie ikh v komplekse pozvolyaet differentsirovat' dannye vidy.
