Morphological characteristics of stems, leaves, bracts, calyces and corollas are taxonomically discriminating characters in Salvia. In this paper we present morphological, anatomical and ecological features of S. limbata C.A. Meyer and S. palaestina Bentham as well as micromorphological characteristics of their pollen grains and nutlets using scanning electron microscopy. Anatomical characters such as size of cortex and vascular tissue, number of palisade parenchyma rows and vascular bundles are found to be important species specific characters. Pollen grains in the species are different in shape and size, but they look similar in their exine sculpturing; shape, size and ornamentation of nutlets are found to be different. The two investigated Salvia species grow on clayey-loamy and loamy soils, with pH 7.6-7.9, with 0.4-2.1% of organicmatter, 0.006-0.026% of total salt content, 4.2-21.0 mg kg-1 phosphorus and 87.0-445.8 mg kg-1 potassium.
