pollen grain morphology of 15 taxa of the hedysareae tribe distributed throughout iran was studied using light and electron microscopy to identify major taxonomical characteristics of pollen grains. the pollen grains were tricolpate and tricolporate, prolate and perprolate. the ectocolpi were elongated, shallow or deep, narrowing at the poles. the colpus membrane was covered by large granules. ...

The legume family (Fabaceae) exhibits a high level of species diversity and evolutionary success worldwide. Previous phylogenetic studies of the genus Hedysarum L. (Fabaceae: Hedysareae) showed that the nuclear and the plastid topologies might be incongruent, and the systematic position of the Hedysarum sect. Stracheya clade was uncertain. In this study, phylogenetic relationships of Hedysarum ...

Herein we describe the nests (including construction, closure, orientation, and depth of cells) of the bee Osmia (Ozbekosmia) avosetta Warncke found nesting near Antalya, Turkey, and Sepidan, Iran. Cells are unusual in that they are lined by two layers of colorful flower petals that sandwich a thin middle layer of mud. Analyses of pollen taken from scopal hairs of specimens from the Turkish sit...

Chlidoplitis and Megahoplitis are closely related Palaearctic subgenera of the osmiine bee genus Hoplitis (Megachilidae) containing nine and two species, respectively. Analysis of female pollen loads and field observations suggest that all species are pollen specialists. Whereas the H. (Chlidoplitis) species are probably all narrowly oligolectic and exclusively collect pollen on Allium (Alliace...
