Morphological characteristics of 16 collected safflower (Carthamus tinctorius L.)accessions were studied at Gyongbuk A.T.A. Uisong Medicinal Plant Experiment Station in 1998. As for plant height, 5 lines were tall(more than 131cm), which were mainly foreign safflower. Middle and small were 5 and 6 accessions, respectively. Number of branch per plant was 11∼13 in 2 accessions of domestic safflowers while foreign safflowers have more than 50 branches per plant. Leaf shapes were oblong(3 lines), lanceolate(10 lines) and broadly linear(3 lines). There were three types of leaf margin shape which were repand(7 lines), serrate(4 lines) and parted serrate(5 lines). Flower color was white(1 line), yellow(13 lines) and red orange(2 lines). As for flower head shape, 14 lines were conical and 2 lines were flattened. There were thorns on bract of flower head in 11 lines but in 5 lines there were not. Domestic safflower lines had seeds of conical shape. Contrastively, seed shapes of foreign saffower lines were oval.
