. A manual of weeds : with descriptions of all the most pernicious and troublesome plants in the United States and Canada, their habits of growth and distribution, with methods of control . Weeds. EUPHOSBIACEAE (SPURGE FAMILY) 263 possible to remove. Professor Selby, of the Ohio State Experiment Station, wisely remarks that "the time to remove such seeds is before the clover is ; Stem six inches to two feet high, erect, somewhat hairy, often purplish or brown. Leaves alternate, two to four inches in length, long ovate, thin, dark green, often turning to a cop- pery brown, coarsely toothed except near the base. In their axils are the inconspicuous greenish flowers, male and female separate, but growing from the same point, the staminate ones being lifted on a tiny spike, the fertile ones just below, and both sup- ported by a large, leafy, cut-lobed bract, longer than either,. usually about a half inch high. Capsules three-celled, each cavity containing one dull reddish brown or gray seed, egg-shaped, and easily crushed be- tween the fingers, which is the reason why they are called Wax-balls.
