The detailed micromorphological features of mature cypselas of fifteen species, seven of Artemisia, three each of Achillea and Leucanthemum and two of Ligularia were studied using light compound and Scanning electron microscopes. Special emphasis was given to the surface structures particularly primary sculpture, cell shape, topography of anticlinal and periclinal walls, secondary sculpture, carpopodium and pappus bristles of cypselas. Six types of primary sculptures were observed, reticulate
