Hair anatomy in Plantago subg. Psyllium (Plantaginaceae)

The hairs of seven representatives of Plantago L. subg. Psyllium were studied. Three types of headless hairs and three types of headed hairs were observed. Clavate hairs and hairs with several-celled stalk and unicellular head are characteristic of subg. Psyllium and provide evidence for the distinc...

Zusammenfassung:	The hairs of seven representatives of Plantago L. subg. Psyllium were studied. Three types of headless hairs and three types of headed hairs were observed. Clavate hairs and hairs with several-celled stalk and unicellular head are characteristic of subg. Psyllium and provide evidence for the distinctness of this taxon. Based on our studies it can be assumed that Rahn's idea of enlarging subg. Psyllium by six sections from subg. Plantago sensu Pilger is incorrect.
