The gross anatomical features, namely stem, blade and petiole and the micromorphological features, trichome, pollen and nutlet of Salvia vermifolia Hedge & Hub.-Mor. (Sect. Aethiopis Bentham, Lamiaceae) were examined using light microscopy (LM) and scanning electron microscopy (SEM). S. vermifolia is a perennial endemic herb growing on igneous and serpentine slopes in Sivas province, Central Anatolia, Turkey. The results obtained from anatomical studies show that the stem is made up of 4-8-layers of collenchyma cells and 1-3-layers chlorenchyma cells. The blade is amphistomatic, bifacial, with 2-3-layered palisade cells on the adaxial. The petiole has three large central bundles and six small subsidiary bundles. Peltate glandular, capitate glandular and non-glandular trichomes are present in S. vermifolia. The peltate glandular trichomes are present in abundance on the calyx and corolla, and capitate glandular trichomes are predominant on the calyx, inflorescence axis, pedicel and stem. The acicular non-glandular trichomes are mainly situated on the calyx, corolla, inflorescence axis and pedicels whereas the floccose non-glandular trichomes are common on both sides of the leaf, inflorescence axis and petiole. The pollen grains are hexacolpate to octacolpate, medium to large (P, polar axis=45.29-62.49 μm; E, equatorial axis=45.32-62.38 μm), oblate-spheroidal to prolate-spheroidal (P/E=0.91-1.02) and their exine ornamentation is bireticulate. The nutlets are 2.70-2.90 mm long and 1.90-2.13 mm wide, brown, ovoid-oblong in their outline, rounded-trigonous in transverse section, and their surface is glabrous and colliculate.
