Abstract: This study was undertaken to determine the morphological variation present within and among Ricinus communis in Egypt. The flowers, leaves, fruits, seeds and pollens of R. communis from different phytogeographical regions were examined with both scanning electron and light microscopy. Twenty two morphological characters were defined. Based on leaf, capsule, seed and pollen features such as pattern of leaf epidermal wax, stomata pattern, capsule and seed ornamentation, seed shape, seed size, seed colour, exine sculpture, aperture type, pollen shape and composition, two morphological patterns were recognized. Leaf, capsule, seed and pollen of each pattern were described, illustrated and compared. Examination of the morphological variation has shown that within R. communis two formae or varieties may be distinguished.
