242 LEGUMINOSAE (PULSE FAMILY) 
standard, narrow, oblong wings, and keel tipped with a sharp, pro- 
jecting point. (Fig. 172.) Pods sessile, imperfectly two-celled, very 
firm and leathery, densely hairy, long-pointed, and filled with small 
seeds which loosen and rattle about in the pods as they become dry. 
Means ‘of control 
Like the preceding plant, White Loco-weed can be killed by deep 
cutting from the root, well below the crown — as was demonstrated 
by a Montana ranchman who lost three hundred lambs out of a 
herd of two thousand in one season from Loco poisoning; the next 
year, while the plants were in bloom in May and June he hired two 
men to dig up the Loco-weeds on an area four miles square, the 
tools used being heavy, narrow, and very sharp steel hoes; the 
plants never sprouted again and no further losses from Loco 
occurred on his ranch. 
WILD LIQUORICE 
Glycyrrhiza lepiddta, Pursh. 
Other English name: Sweet-root. 
Native. Perennial. Propagates by seeds and by rootstocks. 
Time of bloom: May to August. 
Seed-time: July to October. 
Range: Ontario, Manitoba, and Minnesota, to Hudson Bay, west- 
ward to British Columbia and Washington, and southward to 
Missouri, New Mexico, and California. 
Habitat: Open prairies; fields, meadows, and pastures. 
Its hooked pods make this plant very obnoxious to western wool- 
growers, and it is a weed that is exceedingly hard to destroy. 
The rootstocks are long, thick, creeping, stored with sweet juices, 
whence it is called Sweet-root, a translation of the Greek generic 
name. These thick, juicy, deep-lying roots enable it to withstand 
drought and recover from much cutting and grazing. Stems erect, 
branching, one to three feet high, usually scurfy with fine scales. 
Leaves long-petioled, odd-pinnate, with eleven to nineteen oblong, 
pointed leaflets, entire, bristle-tipped, and specked with minute 
scales or dots, being scurfy when young and dotted when old. 
Flowers densely crowded on axillary spikes, shorter than the
