The morphological, anatomical and palynological features of Asyneuma michauxioides (Boiss.) Damboldt (Campanulaceae) were investigated. This species is an East Mediterranean Floristic Element and an endemic in Turkey. In anatomical studies, cross-sections of the root and stem were examined and demonstrated by photographs. It has conspicuous endodermis in which the Casparian bands are indistinct in...
In this study, the anatomical features of the leaf and stem, besides the pollen and nutlet characteristics of Teucrium sandrasicum are investigated. T. sandrasicum, belonging to sect. Teucrium, is an endemic perennial herb growing on serpentine around Muğla province. The anatomical studies on T. sandrasicum revealed that the stem shares the general characteristics of the Labiatae family. The leaves...
The relationships between the closely related Turkish endemic species, Viola sandrasea Melchior and V. kizildaghensis M. Dinç & Ş. Yıldırımlı, are discussed in the present study. Viola sandrasea has been known only from a few gatherings and insufficient description since 1939. Morphological and palynological properties of it are determined in detail and compared to its closest relative V. kizildaghensis...
Salvia macrochlamys Boiss. & Kotschy, which belongs to sect. Salvia Hedge, is a perennial herb usually growing on rocky limestone slopes in eastern Anatolia. In this study, the anatomical features of the root, the stem, the leaf and the petiole, as well as micromorphological characteristics of the pollen and the nutlet of this species have been investigated using Scanning Electron Microscopy...
Pollen morphology of 10 taxa from Turkey, four of them endemic, belonging to the genus Petrorhagia (Caryophyllaceae), P. alpina subsp. alpina, P. alpina subsp. olympica, P. cretica, P. dubia, P. hispidula, P. lycica, P. pamphylica, P. peroninii, P. prolifera and P. saxifraga, has been investigated using light (LM) and scanning electron (SEM) microscopy. Pollen morphology differences among these taxa...
The pollen grains and seeds in six species of Cistanche distributed in Iran were examined. Detailed morphological descriptions of pollen and seed are given for each species. Four microsculpturing patterns are recognized on pollen surface among the species studied: microhammulate, microscabrate, microornate and microgemmate. The seed coat sculpturing among the studied species is constantly alveolate,...
Meiotic behavior, pollen morphology, interphasic nucleus pattern and karyotype description for Senna occidentalis (Caesalpinioideae — Fabaceae) are presented. The species had non-reticulate interphasic nucleus and homogeneous chromosome condensing with minute distal late-condensing portions in prometaphase. In mitotic metaphase, chromosome number was 2n = 28 (9 m + 5 sm), with secondary constriction...
The pollen morphology of Turkish species belonging to sect. Quinqueloculares (Boiss.) Phitos (Campanulaceae) were investigated with a light microscope (LM) and scanning electron microscope (SEM). All examined species are endemic, except Campanula crispa Lam. According to the results of this study, pollen grains of the examined taxa were triporate and spheroidal. Their sculpture was spinose and baculate...
The genus Epilobium L. (Family Onagraceae) with about 200 species is taxonomically complicated due to wide inter-specific gene flow. There is no report on biosystematics of Epilobium species in Iran, therefore we studied 5 species of this genus using a combination of morphological, molecular (ISSR) and palynological data to delimit these species. All data revealed high degree of morphological and...
