Seed heads of Sand Lovegrass 
the soil and adds organic matter to the subsoil. Easy to establish, responds to culti- 
vation; readily controlled, and adaptable for maintenance work on highways and soil 
binding. Often grown in mixtures with other range bunch grasses. Plants erect to 
spreading, and their numerous fine leafy shoots form a very dense turf. May be recog- 
nized by its very short, scaly underground rootstocks and numerous long, upright seed 
stems, 14-8 ft. tall, with seeds borne in spiked clusters spaced at intervals along the upper 
part of the stems. 
SLENDER GRAMA Bouteloua filiformis 
Slender Grama is a tufted, fine-stemmed perennial native to the southern two-thirds of 
the Rio Grande Plain, westward to Arizona. Thrives best in the heavier moderately 
alkaline clays and clay loams. Cannot be recommended north of latitude thirty-one 
degrees north as trials indicate it lacks cold hardiness. Shows considerable resistance 
to drought and is used chiefly for grazing and soil erosion control. 
SUDAN Sorghum vulgare var. sudanense 
An annual, drought-resistant, quick growing and very nutritious sorghum for pasture and 
hay, introduced from Africa in 1909 by the U. S. Department of Agriculture. Sudan has 
now become the most valuable and widely distributed and adaptable of all the summer 
annual grass crops used for green grazing in the central and southern states. Grows well 
on almost any soil, except deep sand in high rainfall belts. May be planted several times 
during the long southern growing season to provide continuous green succulent growth. 
Readily grazed by all classes of livestock and ready to pasture in 4—6 weeks after planting 
when it has attained a height of 2-3 ft. Frequently used to plow under as a green manure 
crop. Finds a place as a soil-control crop to afford protection from wind and water erosion. 
Plants grow 5 to 6 ft. tall, erect, with numerous, fine, leafy, stems. Root system fine, fibrous, 
spreading.
