Could leaf morphoanatomy characters help in the delimitation of Dyckia selloa complex?

Among species of the genus Dyckia Schult. & Schult. f. there are 13 endemic species of the Brazilian states of Rio Grande do Sul and Santa Catarina informally treated as the Dyckia selloa complex. This study employed standard plant anatomy techniques to investigate variation in leaf morphology of species belonging to the genus Dyckia with a focus of establishing characters that help delimit the Dyckia selloa complex. The results allowed the survey of morphological and anatomical characters important for the characterization of species. Such characters include color of spines, the presence of water-storage parenchyma and mechanical hypodermis on both leaf surfaces, and the presence of tetracytic stomata on only the abaxial surface. Analyses support the current delimitation of the complex and recommend the investigation of reproductive and/or vegetative organs to better understand the relationships among these species of Dyckia .

期刊介绍： Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
