Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2009, Vol 55, Issue 2
Abstract
The paper emphasizes the most important histo-anatomical aspects of Sedum telephium L. ssp. maximum (L.) Krock. from Crassulaceae family. Its root, of secondary structure, is protected by a quite thin peridermis. The central cylinder bears few vascular bundles. Generally, the vascular strands are irregularly distributed throughout the water-storage tissue. The rhizome presents cortical amiliferous parenchyma, formed by cells with thin and cellulosed walls. The fleshy aspect of the stem comes from a well developed parenchymatic tissue which occurs in the cortex and pith. The leaves are water storing and do not present a typical palisade tissue; their entire surface presents anyzocitic stomata; the foliar limb is amphistomatic and displays a bifacial-isofacial structure, with normal dorsiventrality.
