A new species of Orobanche (Orobanchaceae) from Turkey

Abstract

Orobanche turcica (Orobanchaceae) is described as a new species from Turkey. The new species is a close relative of O. anatolica. Morphological differences of the new taxon from closely related species are discussed. A distribution map, illustration, as well as pollen and seed microphotographs of the species are provided.

Taxonomic traits in the microstructure of flowers of parasitic Orobanche picridis with particular emphasis on secretory structures

“…Pujadas-Salvá and Velasco 2000;Joel and Eisenberg 2002;Hyun et al 2003;Mohamed and Musselman 2008). Furthermore, many researchers have reported that the two-lipped corolla with a long tube usually curved towards the lower lip is a characteristic trait of species from the section Orobanche (Restuccia et al 2009;Zare and Dönmez 2013), which was observed in O. picridis in the present study as well.…”

“…The colour and microstructure of stigmata is highly important trait in the taxonomy of the genus Orobanche (Kreutz 1995). However, as shown by Zare and Dönmez (2013), the colour of the pistil in Orobanche may differ between species or within one species. The authors observed pink or yellow pistil stigmata in O. owerini and yellow, brown, red, or red-violet colour of this floral part in O. reticulata.…”

“…Researchers investigating the location and density of trichomes in other Orobanche species showed the taxonomic importance of this trait (Table 1 and references wherein) which, similar to the different colour of trichomes (in particular their heads), can be used as a diagnostic criterion for identification of hardly recognisable and little differing taxa. For example, the glandular trichomes present on perianth elements were light yellow in O. picridis, violet in O. owerini, dark violet in O. reticulata (Zare and Dönmez 2013), yellow in O. lammonensis (Pujadas-Salvà and Arguimbau 2008), and white in O. minor and O. purpurea (Toma et al 2007).…”

Rafflesia sharifah-hapsahiae (Rafflesiaceae), a new species from Peninsular Malaysia

“…Species-differentiating characters used in this study to delimit distinction between species includes flower size, pattern of perigone lobes, pattern of diaphragm, pattern of window, size of aperture, number of processes, ramenta, and number of anthers. The application of flower differences have been widely used to differentiate between species in other groups of flowering plants for example in Magnoliaceae (Chen & Zeng, 2013), Hyacinthaceae (Uzunhisarcıklı et al, 2013), and Orobanchaceae (Zare & Dönmez, 2013 Diagnoses: This species is similar to Rafflesia azlanii by the perigone lobes covered by rows of coalesced white warts. It is different from Rafflesia azlanii by the absence of marginal ring of white warts on the periphery of the window, more rows of coalesced white warts on the perigone lobes, higher number of concentric rings of white warts on the window, larger number and rings of circular dots on the diaphragm, larger number and rings of processes on the upper surface of the disc, and more anthers (see Table).…”

Fruit and seed morphology of the tribe Orobancheae (Orobanchaceae) genera in Turkey and its taxonomic significance

“…24 species of Orobanche , 15 species of Phelipanche , two species of Diphelypaea , and one species of Cistanche Hoffmg. (Gilli , , Davis et al , Zare et al , Zare , Zare and Dönmez ). Based on phylogenetic reconstruvtion, Diphelypaea Nicolson and Orobanche anatolica Boiss.…”
