Premières recherches sur la valeur taxonomiques d'une Composée armoricaine:Aster linosyrisBernh. racearmoricanusRouy

Abstract

ResumeL'auteur effectue une comparaison morphologique entre Aster linosyris et la race armoricanus Rouy. Il constate qu'en culture les differences morphologiques entre ces deux taxons persistent malgre quelques modifications. Une observation au microscope electronique a balayage des akenes ne permet pas de mettre en evidence de nouveaux caracteres distinctifs.Il semble que suivant les criteres de ROTHMALER, A. armoricanus puisse etre considere comme une sous-espece. Ce taxon serait une sous-espece endemique armoricaine.
