FIGURE 47.—Sorghum (Sorghum vulgare Pers.) 
Sorghum sudanense (Piper) Staph, sudangrass, a close relative of 
sorghum, consists of many varieties that vary in height and leafiness. 
Sudangrasses differ from sorghums in having smaller stems, generally 
spreading open seed heads, and smaller seeds, and they stool more — 
profusely. Sorghums and sudangrasses are propagated by seeds; 
they behave as annuals or occasionally as weak perennials under local 
conditions.
