The morphology of hairs in species of Plantago L. sectio Coronopus DC.

Abstract

The hairs of 13 representatives of sectio Coronopus DC. genus Plantago were studied. The occurrence of 5 types of headless and 4 types of headed hairs was found. The investigations confirm the correctness of Rahn's (1978) and Dietrich's (1980) classification dividing the sectio Coronopus (subgenus) into two lower taxonomic units. Sectio Coronopus sensu Rahn is characterized by the presence of bottle-like hairs, while sectio Maritima Rahn by the occurrence of morel-like hairs.
