In this study, Minuartia imbricata (M.Bieb.) Woronow, M. aizoides (Boiss.) Bornm., M. circassica (Albow) Woronow of the genus Minuartia L. belonging to the family Caryophyllaceae have been investigated according to their trichome features micromorphology. The trichomes of leaf margins, leaf surfaces, pedicels, and sepals of the three closely related species have been compared and illustrated by using Scanning Electron Microscopy (SEM) and Light Microscopy (LM). M. imbricata and M. aizoides were observed leaf margins as long pubescent of their leaf margins. However, M. circassica was rare puberulous. Although M. aizoides and M. circassica have glandular hairs on pedicel, M. imbricata have not got glandular hairs on pedicel. Also, the taxa have different hair lengths.
