“…Leaf architectural characters have demonstrated valuable taxonomic and systematic data both in fossil and living plants [ 42 – 44 ]. Leaf architecture and venation pattern were examined in numerous families of dicotyledons, among others, Composite [ 45 ], Solanaceae [ 46 ], Bignoniaceae [ 47 ], Hamamelidaceae sensu lato [ 48 ], Leguminosae [ 49 ], Amaranthaceae [ 50 ], Ulmaceae [ 51 ], Fagaceae [ 52 ], and in some monocots [ 53 ].…”

Background The Capparaceae family is commonly recognized as a caper, while Cleomaceae represents one of small flowering family within the order Brassicales. Earlier, Cleomaceae was included in the family Capparaceae; then, it was moved to a distinct family after DNA evidence. Variation in habits and a bewildering array of floral and fruit forms contributed to making Capparaceae a “trash-basket” family in which many unrelated plants were placed. Indeed, family Capparaceae and Cleomaceae are in clear need of more detailed systematic revision. Results Here, in the present study, the morphological characteristics and the ecological distribution as well as the genetic diversity analysis among the twelve species of both Capparaceae and Cleomaceae have been determined. The genetic analysis has been checked using 15 ISSR, 30 SRAP, and 18 ISTR to assess the systematic knots between the two families. In order to detect the molecular phylogeny, a comparative analysis of the three markers was performed based on the exposure of discriminating capacity, efficiency, and phylogenetic heatmap. Our results indicated that there is a morphological and ecological variation between the two families. Moreover, the molecular analysis confirmed that ISTR followed by SRAP markers has superior discriminating capacity for describing the genetic diversity and is able to simultaneously distinguish many polymorphic markers per reaction. Indeed, both the PCA and HCA data have drawn a successful annotation relationship in Capparaceae and Cleome species to evaluate whether the specific group sort individual or overlap groups. Conclusion The outcomes of the morphological and ecological characterization along with the genetic diversity indicated an insight solution thorny interspecies in Cleome and Gynandropsis genera as a distinct family (Cleomaceae) and the other genera (Capparis, Cadaba, Boscia, and Maerua) as Capparaceae. Finally, we recommended further studies to elucidate the systematic position of Dipterygium glaucum.

“…La selección de cuatro especies con amplia variación en la forma de la hoja permitió reconocer que el patrón de venación también es diverso; por ejemplo, pinnado semicraspedódromo festoneado en Packera sanguisorbae, radiado-palmado semicraspedódromo festoneado en Psacalium peltatum, palmado actinódromo en Roldana angulifolia y pinnado craspedódromo mixto en R. lineolata. Los tipos pinnado y palmado ya se habían mencionado para la familia (Felippe y Alencastro, 1966;Paula, 1966;Banerjee y Deshpande, 1973;Ravindranath e Inamdar, 1985;Milan et al, 2006), pero no el patrón de las secundarias para las pinnadas. Estos patrones de venación se establecieron cuando las hojas tenían longitudes de 2-13 mm (etapa a) y alcanzaron su estado maduro, con longitudes de 22-31 mm (etapa c).…”

“…Los trabajos que describen la arquitectura foliar en esta familia son escasos; solamente se han estudiado alrededor del 3% de los géneros y menos del 1% de las especies de la familia. Se reporta venación acrodroma, actinodroma, fl abelada y pinnada (Felippe y Alencastro, 1966;Paula, 1966;Banerjee y Deshpande, 1973;Banerjee, 1978;Ravindranath e Inamdar, 1985;Milan et al, 2006). También se han realizado estudios comparativos que incluyen la morfología y anatomía de la hoja, en los que se hace mención de los patrones de venación (Stuessy, 1976;Puttock, 1994;Freire et al, 2002;Gutiérrez y Katinas, 2006;Milan et al, 2006 Palmatisecto ovado-elíptica denticulado AS Digitacalia orbicular denticulado RP Pippenalia Cuadro 1.…”

Resumen: Para conocer los cambios que ocurren durante el desarrollo del patrón de venación e identifi car si la forma de la lámina determina el patrón de venación en miembros de la tribu Senecioneae (Asteraceae), en este trabajo se describió y comparó el desarrollo del patrón de venación durante la expansión de la hoja de Packera sanguisorbae, Psacalium peltatum, Roldana angulifolia y R. lineolata, cuyas morfologías son contrastantes (formas redondas vs. elípticas, y láminas no divididas vs. fuertemente lobuladas). Se recolectaron desde ápices vegetativos hasta hojas completamente desarrolladas y se aclararon con una mezcla de fucsina básica-NaOH para la observación de la venación. Los resultados mostraron que el tipo de margen, la disección de la lámina y el patrón de venación (venas primarias y secundarias), se establecen en estadios tempranos del desarrollo, cuando la lámina cuenta con alrededor del 3% de su longitud; la forma de la lámina se establece en etapas posteriores. El desarrollo de las venas tuvo un arreglo jerárquico como en otros taxa. Sin embargo, los órdenes de venación difi eren entre lóbulos y dientes. Los lóbulos son irrigados sólo por venas de primer y segundo orden, mientras que en los dientes pueden llegar venas hasta de séptimo orden. Con la forma de la hoja se pudo predecir el patrón de venación, excepto en aquellas de forma elíptica. En las especies de Packera, el patrón de venación semicraspedódromo festoneado se mantiene, sin importar si la lámina está o no dividida. Se concluye que el establecimiento temprano del patrón de venación y la forma de la hoja son caracteres de potencial importancia taxonómica en la tribu Senecioneae. Palabras clave: dientes, expansión de la hoja, lóbulos, órdenes de venación, Packera, Psacalium, Roldana. Abstract:The venation pattern development was described and evaluated during leaf expansion in Packera sanguisorbae, Psacalium peltatum, Roldana angulifolia, and R. lineolata of the Senecioneae tribe (Asteraceae) with contrasting morphologies (round versus elliptical shape, and entire versus deeply lobed lamina). The aims of this study were to identify the changes that occur during the venation pattern development and to determine if lamina shape correlates with the venation pattern. Leaves of different ages from meristematic apexes to fully developed leaves were collected and cleared with a basic fuchsin-NaOH mixture. The results showed that type of margin, dissection of lamina, and the venation pattern (primary and secondary veins) are fi xed since early stages of the development, when the lamina counts on 3% of its length. However, lamina shape is acquired later in development. Veins development followed a hierarchical pattern as described for other taxa. However, venation orders varied between lobes and teeth. Lobes are irrigated by primary and secondary veins, while up to 7 th orden veins are found in the teeth. Leaf shape may predict the venation pattern except when the leaf has an elliptic shape. In Packera the festooned semicraspedodromous venation...

Macro, micromorphological and chemical characteristics of Salvia fruticosa Mill, wild growing in Libya were studied. The aim of the present study is to provide new properties for the identification and description of this species. The features of leaf morphology, verticillaster number, bract, calyx, corolla, stamens, trichomes, collenchyma’s rows, vascular bundle and mesophyll structure are important characters to distinguish this species. In the study, we observe morphologically different types of glandular trichomes. The results of leaf architecture studies can provide a more accurate basis for the identification of this species. The essential oil contained cineol (43.93%), β-pinene (11,43%), α-pinene (9.53%), β-myrcene (9.08%), caryophyllene (8.75%), camphor (5.12%) and α-terpineol (4.15%).
