“…The morphometric analyses of pollen morphological characters were performed to assess relationships that exist among several taxonomic groups (e.g. Olvera et al, 2006;Castro et al, 2009). The findings of the current study show that two different pollen morphological groups correlate with the recent taxonomic delimitation by Hilsenbeck (1990).…”

“…All the species have circular pores and sunken pore ornamentation but the number of pores varies in different species ranging from 11 in S. imbricata to 23 in D. ambrosioides . The quantitative palyno‐morphology is a beneficial source in taxonomic re‐evaluations within tribe because it provides additional data for resolving conflicts based on macro‐morphology (Olvera et al, ).…”

“…The use of LM and SEM is of special interest for the taxonomist to examine various taxonomic features (Khan, Ahmad, Zafar, & Ullah, 2017). Various authors have studied pollen morphology of family Amaranthaceae and Chenopodiaceae worldwide using LM and SEM (Dehghani & Akhani, 2009;Olvera, Fuentes-Soriano, & Hernández, 2006;Punsalpaamuu, Schluetz, Gegeensuvd, & Saindovdon, 2012;Talebi, Noori, & Nasiri, 2016). Moquin-Tandon was the first researcher who carried out the palynological study of Chenopodiaceae (Moquin-Tandon, 1849).…”

The pollen morphology of 11 salt tolerant plant species of family Amaranthaceae from the salt range of Northern Punjab, Pakistan has been studied. The palyno‐morphological characters were examined using light and scanning electron microscope. The examined all salt tolerant species have a slight difference in size but have similarity in shape, pore ornamentation, and polarity. The observed morphological characters of pollen grains were pollen symmetry, size, shape, pore ornamentation, pore size, number of pores, exine thickness, polar and equatorial diameter and, P/E ratio. Apolar type of pollens has been observed in all species. Shape of pollens was spheroidal. Exine sculpturing of pollen grains was scabrate (six spp), microechinate (four spp), and microechinate‐scabrate (one spp). Different pori numbers were observed in different species. The pantoporate aperturate and sunken pore ornamentation have been reported in all species. A pollen taxonomic key was developed using examined morphological characters for the accurate identification of halophytic taxa. The high fertility and low sterility of pollens confirmed that the selected halophytes are well‐established in the salt region. The findings highlight the taxonomic significance of pollen morphology in correct identification and differentiation of salt tolerant plant species.

“…Remarks: Several studies on subfamilies of Amaranthaceae (M€ uller & Borsch, 2005;Olvera, Fuentes-Soriano & Hernand ez, 2006;Dehghani & Akhani, 2009;Hamdi et al, 2009;Toderich et al, 2010) have shown that within a genus pollen characters can be a useful diagnostic tool to distinguish species. However, pollen characters are not informative at subfamily level because of substantial overlap in morphological variability.…”

The middle Miocene palynoflora and palaeoenvironments of Eskihisar (Yatağan basin, south-western Anatolia): a combined LM and SEM investigation

et al. 2016

We investigated a palynological section from middle Miocene sediments at Eskihisar (south‐western Anatolia) to establish biogeographic links of the palynoflora and to infer the palaeoenvironment. Four algal palynomorphs, nine spore taxa, eight gymnosperms, three monocots and 67 dicot pollen types were encountered and investigated using the ‘single grain method’ that combines light microscopy and scanning electron microscopy. Two pollen zones reflect different phases of basin development. Zonal vegetation remained fairly stable across the section and reflects heterogeneous environments including broad‐leaved deciduous forest, subtropical forest and sclerophyllous and semi‐evergreen oak forest. Conifers were accessory elements in the broad‐leaved deciduous forest communities and replaced these at higher elevations. Some herbaceous taxa (Plumbaginaceae) indicate scattered occurrences of sandy and/or rocky soils. Biogeographic affinities are general Northern Hemisphere, North American and East Asian, as also suggested by the macrofossil record. Only two taxa provide potential biogeographic links with the African flora. This suggests that biome shifts of plant taxa between African subtropical/tropical biomes and Anatolian (western Eurasian) temperate forests and shrublands may have been rare in the middle Miocene.
