126 AMARANTHACEAE (AMARANTH FAMILY) 
have a one-celled, one-seeded ovary with two to five plume- 
like stigmas. The small, shining seed drops from its place

and water. (Fig. 78.) 
Means of control 
Prevention of seed development by close cutting or pulling while 
in early bloom. Drainage and cultivation of the ground.

Stem erect, furrowed, swollen at

narrowly ovate, long-pointed, be-

smooth and entire, with short, slen-
