“…The pollen of genus Onobrychis shows the tricolpate pollen having prolate shape. The exine is reticulate, supra reticulate or micro reticulate in the genus (Avci, Sancak, Can, Acar, & Pinar, ). These features were also seen in O. dealbata .…”

Pollen morphology of 10 species and foliar epidermal anatomy of eight species of Papilionaceae from Skardu valley, northern Pakistan has been estimated for the first time. The present study was commenced with an aim to provide a detailed account of the pollen morphology by scanning electron microscopy and foliar epidermal anatomy by light microscopy. The pollen aperture was tricolporate with reticulate exine in the selected species. Stomata types are actinocytic, paracytic, and anomocytic. Irregular or polygonal with undulate or straight walls, epidermal cells were reported. A unique diversity was observed in the foliar trichomes that show the taxonomic significance of the discrimination of taxa. Non‐glandular trichomes were observed in the selected species which are unicellular with thin, long and pointed apical cells. Pollen and foliar micro morphological characters proved to be helpful for the identification of taxa at a specific level.

“…Many researchers have found positive correlations between genome size and some phenotypic plant traits, such as seed mass, dimensions of different types of cells, or plant height (Beaulieu et al, 2007;Knight and Beaulieu, 2008;Avcı et al, 2013). The hypothesis is that species with larger genomes tend to have larger cells and heavier seeds through genome size effect on cell size within seed organs (Beaulieu et al, 2007;Linkies et al, 2010).…”

The pollen and seeds of 3 paleoendemic resurrection species, Ramonda myconi (L.) Rchb. (Iberian Peninsula), R. nathaliae Pančić & Petrović, and R. serbica Pančić (Balkan Peninsula), as well as of natural hybrids between the 2 last species, have been analyzed using light and scanning electron microscopy. Their general structural differences, taxonomic and phylogenetic significance, pollen viability, and seed germination capacity, as well as the correlation of pollen and seed characteristics and plant ploidy levels, have been studied. The pollen grains are small (R. myconi, R. nathaliae) to medium (R. serbica) in size, ranging from 10 to 28 µm, and 3-colporate, isopolar monads with microreticulate-perforate exine. Seeds are small, 309 to 1000 µm long and 80 to 425 µm wide, elongated, with a reticulate surface and auriculate ornamentation. Micromorphologies of the pollen exine ornamentation and seed surface revealed significant differences among the 3 species. Pollen from hybrid individuals was heterogeneous in size and morphology, and the germination of their tiny seeds was very low. A strong correlation was found between pollen size, DNA content, and chromosome number. The environmental influence on pollen and seeds of 3 species and especially of the R. nathaliae population growing on serpentine is also discussed.

“…Yildiz et al (1999), for example, outlined a classification based mainly on fruit morphology using a sample of 40 species for 5 sections of a total of 162 species classified into 2 subgenera and 8 sections. In addition to the other morphological data, Dolya and Vasilissa (2000) and Avcı et al (2013) used pollen morphology, while Irfan et al (2007) used electrophoretic analysis of total seed proteins to study the systematics of Onobrychis. Unfortunately, the number of species included in these last 2 studies was too low to draw clear general conclusions on the genus.…”

which were previously treated in tribe Galegeae, were transferred to tribe Hedysareae by . Members of Hedysareae are commonly found in dry open habitats with a continental, temperate, or Mediterranean climate, including Eurasia, North America, and the Horn of Africa (Ahangarian et al., 2007). Some taxa of the tribe are economically important as fodder legumes due to their high protein content (Hayot Carbonero et al., 2011).Molecular analyses by Wojciechowski et al. ( 2004) and Lavin et al. (2005) showed that Caragana Fabr. was the most closely related sister group to the rest of the tribe Hedysareae.Hedysareae is included in the Inverted Repeat Lacking Clade (IRLC) group sensu Wojciechowski et al. (2000Wojciechowski et al. ( , 2004 and Wojciechowski (2003Wojciechowski ( , 2005. In more recent studies, it has been suggested that Hedysareae sensu Lock ( 2005) is a sister group to the Astragalean clade, which includes genera such as Astragalus L., Oxytropis DC., and Colutea L., in addition to Chesneya Bertol. and its close relatives . According to Lavin et al. (2005) the most recent common ancestor of the Hedysareae and the Astragalean clade originated between 25.0 and 39.2 million years ago.The genus Onobrychis is divided into 2 subgenera:
