Abstract
Morphological, anatomical and palynological characteristics of Salvia glutinosa L. and S. staminea Montbret & Aucher ex Bentham and their taxonomic importance are presented. Their expanded description and phenology are also given. The features of stems, leaves, calyces, corolla and nutlets have been found to be significant to distinguish the species. Mesophyll structure, distribution of stomata on upper epidermis, size of stomata on lower epidermis, shape of vascular structure in midrib, and number of vascular bundles and presence of sclerenchymatic fibers in petiole are diagnostic characters. Moreover, pollen size and exine ornamentation are important in separating these two species. Keywords: Morphology; Anatomy; Palynology; Salvia. DOI: 10.3329/bjpt.v16i1.2749 Bangladesh J. Plant Taxon. 16(1): 73-82, 2009 (June)
Highlights
Salvia L. (Lamiaceae) is represented by about 1000 species displaying a remarkable diversity in growth forms, secondary compounds, floral morphology, and pollination biology
The first revision of Salvia L. in Turkey was made by Hedge (1982), who recognized 86 species, one hybrid and one doubtful species
The genus Salvia has been subject to a number of studies mainly based on morphological (Hedge, 1982), anatomical (Metcalfe and Chalk, 1965; Kaya et al, 2007; Kahraman et al, 2009a, b) and palynological (Cantino et al, 1992) information
Summary
Salvia L. (Lamiaceae) is represented by about 1000 species displaying a remarkable diversity in growth forms, secondary compounds, floral morphology, and pollination biology. S. glutinosa and S. staminea belong to different sections, some morphological characteristics of these two species overlap such as stem indumentum, leaf size, petiole length, inflorescence length, number of verticillasters, stamen type, and bract shape and size. Transverse sections of the stem of Salvia glutinosa (Figs 1-4) and S. staminea (Figs 5-8).
