The morphology of hairs in Plantago famarae Svent.

Emilia Andrzejewska-Golec, Jacek Świętosławski

Abstract


This paper is a part of a series of investigations on hairs in the genus Plantago L. It deals with an endemic taxon - Plantago famarae Svent. which has not been investigated yet in respect to hairs. The presence of two types of headless hairs and two types of headed hairs was observed. The results of this study are compared to those of another work on two other species from the Canary Islands. P. famarae does not differ from P. arborescens by either hair type or distribution. However, in contrast to P. webbii it has no web-like hairs while hairs with a multicellular stalk and unicellular head hairs (characteristic for the taxa of subgenus Psyllium) are distributed in a different way.
