Abstract :

Brachythecium is one of the genus of Brachytheciaceae family that has 14 species in Iran specially in Hyrcanian region.Many species of Brachythecium exhibit a broad range of variation. In this study, foue species of this genus consisting B. salebrosum, B. rutabulum, B. rivular and B. mildeanum were comparised based on morphological and anatomical characters in Savadkooh forests of Mazandaran province. Our results showed that leaf shape, basal cells of leaf , margins plane and costa characters are an important to distinguish their species. B. salebrosum is charactrised by slightly falcate, lanceolate leavesrather distinctly serrulate leaf margins, narrow laminal cells almost reaching the leaf base near the costa, and a small quadrate alar region composed of subquadrate cells. In B. mildeanum leaf margin and apex shape of leaf can distinguished this taxon from another species. In B. rivular, that closely resemble B.rutabulum, distinct patches of colorless cells and basal cells are different from another lamina cells.
