- 25 Downloads
Scanning electron microscopic studies on the leaves of 8 medicinal salvias comprising mainly surface ornamentation of the various epidermal cells and the appendages, provide useful parameters to distinguish one species from another. Some of the distinguishing features of the species studied are:Salvia cabulica Benth.—Striated lower epidermis, etomatal ledges broad and smooth;S. lanata Roxb.—Abaxial side completely covered over by a thick coat of trichomes;S. macrosiphon Boiss.—verrucose trichomes with constricted joints;S. moorcroftiana Wall.—longitudinal folds on basal cells of trichomes;S. officinalis Linn.—curved cylindrical trichomes, cells over veins with characteristic longitudinal ridges, gland stalk very long;S. plebeia R. Br.—basal cells of trichomes transversely striated;S. pratensis Linn.—verrucose trichomes and series of irregular folds on lower epidermis;S. spinosa Linn.—smooth collapsible hairs, folds on general surface similar toS. pratensis.
