14) If the flower wasn't there, the easiest way to tell the difference between Saw Grass and Cattails is by the blades. In these cross sections, Saw Grass is on the left and it is sharply angled about 90 degrees on the inside, and the blade is relatively hard. They call it Saw Grass because if you run your finger along the edges of the blade, tiny barbs make it feel like a saw whereas the cattail blade is smooth. The spongier and softer Cattail blade cross section is the one on the right - it is thicker in the center and gently curved instead of sharp angled. |
