CHAPTER V. 
GRASSES CLASSIFIED ACCORDING TO 
THE ANATOMICAL CHARACTERS OF THE LEAF. 
| wee be CHLOROPHYLL-TISSUE, ON TRANSVERSE SECTIONS, 
IS ARRANGED IN RINGS ROUND THE VASCULAR 
BUNDLES. ‘THERE ARE MOTOR-CELLS BETWEEN THE 
RIBS, AND THE STOMATA ARE SUNK AND OCCUR ON 
BOTH FACES, 
Cynodon Dactylon. The larger lateral nerves have as 
a rule three smaller ones between each pair, hardly pro- 
jecting as ribs. Chlorophyll chiefly in a ring round the 
vascular bundle. Long hairs on lower surface, a few 
papillze above. Motor-cells in each shallow furrow. Short 
cells occur between the long epidermal cells over the 
bast-region. 
The Panicums also come here, and differ according to the 
disposition of the sclerenchyma sheaths around the bundles.
