FIG. 2. — Serial cross sections from below upwards through a floral bud of Raphanus sativus L. showing: A, pedicel vasculature; dissected siphonostele; B-F, calyx vasculature; four sepal median bundles arise directly from the central stele as distinct sepal median traces, two antero-posterior ramified and two laterals unramified; C-E, corolla vasculature; from petal-sepal marginal complexes; D-I, androecium vasculature; six staminal bundles to six fertile stamens emerge directly from the central stele; J-N, gynoecium vasculature; ten vascular masses; two dorsal carpellary bundles, two ventral carpellary masses, four lateral carpellary bundles and two septal bundles. Scale bar: 500 μm.
