1 Grasses and Grass-like Plants 25 Major Rangeland Plants By Karen Launchbaugh

2 Grass Morphology Spike Panicle Most grasses a have Spike or Panicle inflorescence

3 Sodgrass vs Bunchgrass Sodgrass Bunchgrass Rhizomes are below-ground modified stems that give rise to new plants. Solons are above-ground modified stems that give rise to new plants.
