Some aspects of the pollen morphology of the genus Sanguisorba L. (rosaceae)

Abstract

Eight species of the genus Sanguisorba L. were studied. Two distinct types could be recognized, viz., the Sanguisorba minor and the Sanguisorba officinalis type. Sanguisorba filiformis (Hooker fil.) Handell-Mazzetti appeared to be a transition between these two types.
