Seed Morphology of some taxa of the genus Euphorbia L. (Euphorbiaceae) in Turkey and its taxonomic significance

The morphological characteristics of seeds are not affected by environmental factors and can be used to identify the Euphorbia taxa. present study aims determine in 27 taxa using scanning electron microscopy (SEM) light microscope (LM). Findings revealed that show variation size, color, seed surface ornamentations among different species. vary also shape from ovoid, ellipsoidal, globose, quadrangular, compressed, compressed-ellipsoidal with two exceptions E. petiolata (oblong--quadrangular truncate), macrocarpa (subglobose), szovitsii var. kharputensis(ellipsoidal quadrangular truncate). Furthermore, it was demonstrated caruncle shape, studied spp. Special attention paid lipid granules indicating their broad ellipsoidal globose reniform, although were absent some In addition, lack any caruncle. unweighted pair group method arithmetic mean principal component analysis assess differentiation According dendrogram plot obtained cluster PCA analyses, divided into four clusters corroborating previous molecular phylogenetic results.
