Near the marginthe circular cells are small and are usually accompanied by crescent-shaped cells which often exceed them, in size. On the greater part of theglume, however, the circular cells are much larger, often being 70 /i indiameter. Numerous pores are conspicuous, both in the radial andtangential walls. Often one, sometimes two, crescent-shaped cells ac-company a circular cell. Characteristic of this coat are the short, wavy cells and the numerouscircular cells, the latter frequently exceeding in area the former. 2. Hypoderm. The fibers in this layer are much the same as incereals. Fibers of similar structure also make up the ground tissue ofthe awn. 3. Spongy Parenchyma.
