Two new species of Cotoneaster (Rosaceae, subgen. Chaenopetalum) for the flora of Iran

Abstract

Cotoneaster nima-yushiji and C. mazandaranicus (sect. Chaenopetalum), two new species of the genus Cotoneaster (Rosaceae) from northern Iran, are described and illustrated. Cotoneaster nima-yushiji is closely related to C. discolor Pojark. (1954: 16) but differs by larger leaves, indumentum of leaves, number of flowers per inflorescence, longer inflorescence, dark red and succulent fruit (vs. light red and non-succulent). C. mazandaranicus is morphologically similar to C. multiflorus C. A. Mey. (1831: 171), but is distinguished by foliar lamina with base narrowly cuneate to cuneate, shape and size of leaves, indumentum of leaves, color of leaves and fruit.

Taxonomic study of one generic and two new species record to the flora of Pakistan using multiple microscopic techniques

“…Previous studies adopted microscopic techniques for addition of new species record, plant systematics, anatomical, micro, and macro morphological studies and finding variations among medicinal plants authenticity (Bahadur et al, ; Bahadur et al, ; David, Ain, Ahmad, Zaman, & Jahan, ; Esfandani‐Bozchaloyi & Zaman, ; Raei Niaki et al, ; Shah, Ahmad, Zafar, & Zaman, ; Shah et al, ; Shah et al, ; Shah et al, ; Shah et al, : Ullah et al, ). To introduce new species in Pakistan flora, the taxonomist and scientists contributed in this regard.…”

Nonglandular trichomes (NGTs) were three cells long, whereas glandular trichomes were noted as capitate glandular trichomes at the abaxial surface ( Figure 3).…”
