| dc.description.abstract | result of an investigation into the possible taxonomic value of comparative petiole anatomy in 46 taxa of the genus Biscutella (Cruciferae) is presented. The shape of the petioles varies from dorsiventrally flattened to subcircular or circular in transections with abaxial surface convex and adaxial surface convex or concave. In all taxa the vascular structure consists of a single collateral principal bundle accompanied by subsidiary strands in the wings. Shallow crescentiform, deeply crescentiform and U-shaped bundles all occur within the genus. The perivascular tissue may be composed of either sclerenchyma or collenchyma, or both. In some cases the anatomical features have provided characters which are of practical taxonomic use in distinguishing the species. The relative homogeneity of many anatomical characters in other groups of taxa reflected the close genetic relationships existing between them. | en_US |
