Fig. 17 Rosa rugosa, flower development. Axial sections through floral primordia in different stages of development, schematic. Apical meristem and petal primordia (P), stamens (St) and carpels (F) dotted. The "periclinal rows" which result from active division of young cells are shown with diagonal lines. Intercalary meristems which form the receptacle and the pedicel shown by shading of horizontal lines, K calyx, B primordia of lateral flowers. After Rauh and Reznik, somewhat modified.
