Tres especies nuevas de Myrtaceae de la Sierra Madre Oriental, México
2016Co-Authors: Sánchez-chávez Erandi, Zamudio SergioAbstract:Abstract Three new species of Myrtaceae from Querétaro and Hidalgo, México are described and illustrated: Calyptranthes moctezumae, Eugenia queretaroana and E. huasteca. Calyptranthes moctezumae is related with C. schlechtendaliana and C. schiedeana, from which it is distinguished by the lesser number of nerves per leaf, petioles 1 to 5 mm long, and because it occurs in tropical deciduous and subdeciduous forest, as well as submontane scrub. Eugenia queretaroana is similar to E. crenularis and E. pueblana; nevertheless, it is distinguished by the coppery Indumentum, terete petiole, infundibuliform hypanthium, and ellipsoid fruit with a false stipe at base. Eugenia huasteca is related with E. capuli; however, the new species is distinguishable from all the other species in the genus by the brownishred to whitish Indumentum of simple hairs and the sessile flowers.Resumen Se describen e ilustran tres especies nuevas de Myrtaceae de los estados de Querétaro e Hidalgo: Calyptranthes moctezumae, Eugenia queretaroana y E. huasteca. Calyptranthes moctezumae está relacionada con C. schlechtendaliana y C. schiedeana, de las que se distingue por el menor número de nervaduras por hoja, peciolos de 1 a 5 mm de largo, y por habitar en bosque tropical caducifolio, subcaducifolio y matorral submontano. Eugenia queretaroana es similar a E. crenularis y E. pueblana, de las que se diferencia por el indumento cobrizo, peciolo terete, hipantio infundibuliforme y frutos elipsoidales con un falso estípite en la base. Por su parte Eugenia huasteca se puede relacionar morfológicamente con E. capuli; sin embargo, la primera presenta indumento simple, pardo rojizo a blanquecino y flores sésiles, características que la separan claramente de cualquier otra especie de este género

micromorphological studies on nutlet and leaf Indumentum of genus teucrium l lamiaceae in iran
Turkish Journal of Botany, 2011Co-Authors: Maryam Eshratifar, Farideh Attar, Kazem MahdigholiAbstract:The micromorphology of leaf Indumentum and nutlet surface of 12 species belonging to the 6 sections of the genus Teucrium L. was studied by scanning electron microscope (SEM). Eight types of trichomes are identified including unbranched unicellular trichomes, unbranched multicellular trichomes, sessile glands, subsessile glands, stalked-multicellular glands long clavate glandular trichomes (with 3-5 cells), trichomes with large thin-wall, trichomes with non-micropapillate basal cell, which are the most general types on the adaxial side of the leaves, and branched trichome with long axis is the exclusive type and present in Teucrium polium L. Thus, trichomes can be used as a distinctive taxonomic character in species classification. Nutlet shapes in most species are elliptic-ovate, the surface of which is polygonal with different ornamentations and wall thickness, and the Indumentum varies in different species, but it has some significant similarities within the sections. The absence or presence of the Indumentum and its different types has high taxonomical values among the species.

leaf Indumentum in some turkish species of teucrium lamiaceae
Istanbul Journal of Pharmacy, 2019Co-Authors: Gulay Ecevitgenc, Taner Ozcan, Tuncay DirmenciAbstract:DOI : 10.5152/IstanbulJPharm.2018.374759 Trichome micromorphology can be used as a discriminating character in the separation of species and subspecies. The micromorphological characteristics of foliar trichomes from five Teucrium taxa (T. scordium subsp. scordium, T. sirnakense, T. chasmophyticum, T. andrusi and T. spinosum) were investigated by scanning electron microscope. Seven types of trichomes were identified, including glandular and non-glandular. The glandular trichomes were recorded in three types; short clavate, long clavate, and subsessile. The non-glandular trichomes were identified with four types; unicellular thin-walled, 2(5)-celled thin-walled, 3–7(11)-celled flexuose, elongated thin-walled and 2-celled thick-walled trichomes. Generally, the trichome types were similar on both sides of the leaves, except in T. spinosum. Subsessile glandular trichomes were the most common type and were occurred in all the investigated species. Also clavate glandular trichomes were found in all the species, except T. scordium subsp. scordium. All trichomes were distinctively thick-walled, whereas thin-walled trichomes were observed in only T. chasmophyticum species. The leaf micromorphology of T. sirnakense and T. chasmophyticum has also been reported in detail for the first time in this study.

micromorphological characters on nutlet and leaf Indumentum of teucrium sect teucrium lamiaceae in turkey
Turkish Journal of Botany, 2015Co-Authors: Gulay Ecevit Genc, Taner Ozcan, Tuncay DirmenciAbstract:Leaf Indumentum and nutlet surface micromorphology of 13 taxa belonging to the Teucrium sect. Teucrium was studied with a scanning electron microscope. We observed 5 trichome types on the nutlets and 8 trichome types on the leaves. Branched trichomes were not found on the nutlets. Nutlet shapes of the taxa were elliptic, obovate, oblong, or rotund, and their surfaces were generally alveolate with different ornamentations. Some nutlets had longitudinal ridges. The Indumentum varied among unrelated species and showed some significant similarities within related species. In Flora of Turkey sect. Teucrium was divided into 2 groups according to leaf fragmentation and other morphological characters. The current study supports this grouping. The Indumentum types on nutlets and leaves have a high taxonomical value for the species of the genus.
