LEGUMINOSAE (PULSE FAMILY) 229 



LOW LUPINE 

 Lupinus puslllus, 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 



Trifblium arvense, 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.
