The morphology of 11 species of the genus Vicia from Iran was studied using Scanning Electron Microscopy (SEM). The main pattern in seed coat sculpturing in the species was papillose, but the size and the number of side ribs in papillae and the density of papillae, were different in various species. Four morphological characters of seeds: relative hilum length and shape, relative position of th...

Two new species of Alcea L. (Malvaceae)in Iran, namely, A. iranshahrii from Fars Province and A. mazandaranica from Mazandaran Province are described. Their descriptions and taxonomic relationships are also given. In addition, seed coat microsculpturing is examined using Environmental Scanning Electron Microscope (ESEM). The seed coat patterns observed are fairly uniformed among the genus. It w...

It has been reported that wild Brassica and related species are widely distributed across Xinjiang, China, and there has been an argument for species identification. Seed coat microsculpturing (SCM) is known to be an excellent character for taxonomic and evolutionary studies. By identifying collections from Xinjiang, China, and combining SCM pattern, flow cytometry, and genome-specific DNA mark...
