Cytology of the Genus Sanguisorba

Abstract

THE genus Sanguisorba L., comprising about 40 species, has been the object of several cytological and taxonomical studies during recent years. Thus we have already gained a rather good idea of the cytological pattern of this genus^1,2. In particular, specimens of the form complex Sanguisorba minor, from all over its distribution area, have been studied. The species forms a polyploid series of 7. Up until now tetraploids, hexaploids and octoploids have been found, but never diploids. I have examined neighbouring monotypic genera with woody structure^3,4; they too turned out to be tetraploids, namely, Bencomia caudata, Dendriopoterium menendezii, Marcetella moquiniana, and Poterium spinosum.
