LEGUMINOSAE (PULSE FAMILY) 229 
LOW LUPINE 
Lupinus pusillus, Pursh. 
Other English names: Blue Pea, Low Blue Bean. 
Native. Annual. Propagates by seeds. 
Time of bloom: April to June. 
Seed-time: June to August. 
Range: Kansas, Nebraska, and the Dakotas, westward through- 
out the whole Rocky Mountain region to the Sierra Nevadas, 
southward to Arizona and New Mexico. 
Habitat: Dry soil; upland pastures and meadows. 
A low but rather stout plant, four to eight inches tall, the stems 
diffusely branched from the base and covered with fine, spreading 
hairs. Leaves on slim hairy petioles slightly dilated at the base; 
leaflets five to seven, oblong, sessile, smooth above but hairy under- 
neath, little more than an inch in length and tapering toward the 
base from slightly wider tips. Racemes terminal, one to three inches 
long, on very short peduncles, the pea-like flowers closely crowded, 
small, about a quarter-inch in length, deep blue. Pods about 
three-fourths of an inch long, densely hairy, tipped with an awl-like 
beak, usually two-seeded. 
Low Lupines furnish an immense amount of good forage in 
spring and in autumn, but during the season of seed development 
they are considered dangerously unwholesome for grazing animals, 
particularly sheep. 
Means of control 
As the plant is an annual, the persistent prevention of seed devel- 
opment by frequent close cutting will destroy it. Dormant seeds 
may furnish a subsequent crop, which should have similar treatment. 
RABBIT-FOOT CLOVER 
Trifolium arvénse, L. 
Other English names: Stone Clover, Old-field Clover, Pussy Clover, 
Hare-foot Clover. 
Introduced. Annual. Propagates by seeds. 
Time of bloom: May to July. 
Seed-time: June to August.
