A New Genus, Turanecio, Of The Asteraceae (Tribe Senecioneae), Ergi̇n Hamzaoğlu, Ümi̇t Budak, Ahmet Aksoy Jan 2011

A New Genus, Turanecio, Of The Asteraceae (Tribe Senecioneae), Ergi̇n Hamzaoğlu, Ümi̇t Budak, Ahmet Aksoy

Turkish Journal of Botany

Turanecio Hamzaoğlu, a new genus of the Asteraceae, is described. Ten species are included, previously referred to Senecio L., Cineraria L., or Iranecio B.Nord. This genus belongs to the "Quadridentate Group" of the subtribe Senecioninae, because of the 4-lobed disc florets. The new genus closely resembles Dolichorrhiza (Pojark.) Galushko, but differs by the thickish rhizome, the short-sagittate anther bases, the style branches with papillate lower surface, and in possessing a persistent pappus. Turanecio is centred in Turkey, with species in the Caucasus, Iran, and Iraq.

A Comparative Assessment Of Fruit Formation In Some Orchid Species From The Southern Caucasus Region, Houshang Nosrati, Roghieh Hajiboland, Ahmad Razban-Haghighi, Maryam Nikniazi

Turkish Journal of Botany

The distribution and population size of 5 orchid species (Cephalanthera longifolia, Orchis simia, Platanthera bifolia, Dactylorhiza romana, and Ophrys scolopax) were studied in the southern Caucasus based on the individual numbers in a given area. The fruit set was recorded for the latter 3 species and compared in natural and control groups (pollinators prevented) for D. romana and O. scolopax. We compared the obtained fruit set values with those reported from other regions. The distributions of the 5 species were completely fragmented and the population sizes were extremely small. This is the first report of O. scolopax from the region, …

Cultural Botany: Toward A Model Of Transdisciplinary, Embodied, And Poetic Research Into Plants, John C. Ryan Jan 2011

Cultural Botany: Toward A Model Of Transdisciplinary, Embodied, And Poetic Research Into Plants, John C. Ryan

Research outputs 2011

Since the eighteenth century, the study of plants has reflected an increasingly mechanized and technological view of the natural world that divides the humanities and the natual sciences. In broad terms, this article proposes a context for research into flora through an interrogation of existing literature addressing a rapprochement between ways to knowledge. The natureculture dichotomy, and more specifically the plant-to-human sensory disjunction, follows a parallel course of resolution to the schism between objective (technical, scientific, reductionistic, visual) and subjective (emotive, artistic, relational, multi-sensory) forms of knowledge. The foundations of taxonomic botany, as well as the allied fields of environmental …
