The Epicarp (epi) consists of partiallycollapsed cells. In surface view they are elongated and often showyellowish contents. 2. Crystal Cells (cr). These are arranged in indistinct rows formingan interrupted layer. They are rounded and have light-brown walls 204 OIL SEEDS. which are so thickened that the single monoclinic crjstal of calciumoxalate completely hlls the cavity. 3. Hypoderm. The pitted cells are characterized by the numerousprojections of the outer walls (//y) and the pitted side walls (V/y-). 4. The Mesocarp consists of one to several layers of pitted cells {mes). 5. Endocarp. The cells of this layer, as well as of the papery dis-sepiment (Fig. 162), into which it passes, are transparent, pitted, usually elongated; and are arrangedin beautiful parquetry patterns
