The Palisade Cells (Figs. 215 and 216, pal), 60-75 / ^^S^^ ^^^8-20 n broad, have- narrow cavities in the outer, broad cavities in the FENUGREEK. 261 muc inner portions. On the outer surface the side walls are continued intopointed or, less often, blunt ends 8-20 /x long, projecting into an outermucilaginous coat, the latter being indistinct in water and entirely in-visible on the addition of alkali. The cells with blunt ends are higherthan the pointed cells. A narrow lightKne 3-6 jx is situated 25-35 {x fromthe outer ends of the cells. 2. The Column Cells (Figs. 215 and216, suh), although but 15-20 fx high,are quite as remarkable as the pahsadecells. They are hour-glass-shaped, butthe inner end is much broader thanthe outer. Particularly striking are theribs, which may be se
