Abstract This study focuses on the macro‐micromorphological achene characteristics of 12 species genera Crupina , Jurinea and Klasea (Asteraceae) using light microscopy scanning electron (SEM). The morphological achenes, including shape, size, color, surface pattern achene, hair structure, length, color pappus are studied. results show that length is between 3 8 mm, its width 1 4 mm. Pappus 4–15 mm long persistent for seven species. SEM analysis shows four different patterns studied species: smooth, undulate, smooth‐undulate, undulate‐ruminate. genus has darkly colored achenes with yellow, dense firm hairs, smooth. Triangular sulcate seem to characteristic Jurinea. distinguished from remaining straw‐colored deciduous pappus. Macro‐micromorphological provide effective tools both generic intrageneric differentiation
