In the present study, trichomes of 70 spp. from nine genera and pollens of 53 spp. from six genera were investigated using scanning electron microscopy (SEM) in order to draw the taxonomic conclusion of tribe Stachydeae. Trichome characters that can provide adequate variation in delimitation of taxa were: presence or absence of glandular or nonglandular trichomes, number of cells (uni-/bi-/multicellular), presence of extremely long trichomes (i.e.
