Taxonomical, morphological and anatomical studies on Lallemantia fisch. & mey [Lallemantia fisch. & mey. ci·nsi· üzeri·nde taksonomi·k, morfoloji·k ve anatomi·k araştirmalar]

Abstract

The genus Lallemantia Fisch. & Mey. belongs to Lamiaceae (Labiatae) family, is represented by 3 species in Turkey: Lallemantia peltata (L.) Fisch. & Mey, L. iberica (Bieb.) Fisch. & Mey. and L. canescens (L.) Fisch. & Mey. The taxa grow in central, north, south and east Anatolia and they are element of Irano-Turanian phytogeographic region. In this study, Turkish Lallemantia species (L. peltata, L. iberica and L. canescens) were investigated morphologically and anatomically for the first time and supported with hand drawings and photographs. Morphological and anatomical properties of species were investigated in detail and also anatomical structures of the root, stem and leaf were clarified after our surveys. According to the results, L. canescens is perennial, has grey-canessent indumentum and is the tallest; leaf, bracteol, calyx, corolla sizes are also longer than other two species. L. peltata and L. iberica are the most relative species. In all taxa root anatomy was consisted of periderma the most outer layer, undilated cork tissue and phelloderma. Stem collenchyma was grouped together at the corners characteristically. Phloem and xylem were regular cylinders. Leaves of all taxa were dorsiventral and amphistomatic. Covering hairs of the stem and leaf were uniseriate, 1-4-celled and papillate.
