This study investigated the morphological features (namely, whole plant, leaf and stem anatomy, leaf architecture, and epidermal characteristics) and molecular characteristics of Araliaceae taxa to explain the diversity and diagnostic significance of these attributes. The sum of both characteristic states of morphological and molecular criteria (182 traits and 78 bands, respectively) from the total (260 traits) of the examined taxa was subjected to a numerical analysis using the NTSYS-PC program (version 2.02). The generated dendrogram explained the similarities and differences between the examined taxa and the specific relationships are discussed and compared with current classification systems. The generated dendrogram from morphological attributes confirmed the separation of Aralieae and Schefflerieae as two tribes of Araliaceae and supported the separation of simple leaved taxa from compound-leaved ones.

The present study investigated morphological features, leaf and stem anatomy, leaf architecture, epidermal characteristics, and molecular characters of some taxa of Araliaceae to trace out the diversity and the diagnostic significance of these attributes. The studied taxa based on combination of 260 characters representing 182 morphological and 78 molecular characters which were subjected to a numerical analysis using NTSYSPC program. The generated dendrogram explained the similarities and the differences between the examined taxa. The specific similarities are discussed and compared with some current classification systems. The generated dendrogram from morphological attributes confirmed the separation of Aralieae and Schefflerieae as two tribes of Araliaceae and supported the separation of simple leaved taxa from compound leaved.

Undoubtedly, light is a key element for human beings to adapt to their environment and to see the form, the color, and the perspectives of different objects in their immediate surroundings. Almost 80 percent of the information we obtain daily through our senses we obtain through sight. The correct design of the illumination system and building facades should offer optimal conditions for visual comfort. To achieve this aim, a collaboration between architects, lighting designers, and engineers should be established to improve citizens' quality of life. This paper sought to bridge this knowledge by finding the link between daylighting, the building façades, and visual comfort. Accordingly, the paper conducts a theoretical review to evaluate the existing studies in an attempt to present this linkage focusing on kinetic façades. Then, an analytical review is conducted for 38 eligible records, that are extracted from different scholarly databases to find the assessment methods and tools used to determine the most favorable conditions of daylight for intelligent facades. Ultimately, the outcomes of the research will provide insights for further studies, in addition to that these connections can inform policy development to assist architects to design effective facades and more adaptive capabilities designed for the building envelope. Kinetic facades were found to provide visual comfort in addition to various productivity, economic, and environmental benefits, which in turn enhance the quality of life.
