. 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. 226 LSGUMINOSAE {PULSE FAMILY) each extending beyond the tip in a minute, bristly point. Flowers numerous and very showy, on long terminal racemes, the corollas purplish blue, sometimes white; shaped like pea-blossoms, with standard turned backward at the sides, the wings united and enclosing the small, curved keel; stamen tube not cleft, its anthers of two forms; style incurved; calyx two- lipped and deeply toothed. Pods broad, flat, very hairy, about an inch and a half long, two-valved, splitting in spiral coils at maturity and flinging to some distance the four or five seeds contained; these have long vitality, often remaining dor- mant in the soil for many years. The seeds are also said to be very unwhole- some for grazing animals, though not so dangerously harmful as those of its west- ern relatives. Pig. 161. —Wild Lupine (Lupinus permnis). x J. Means of control Prevent seed development by cutting before the first flowers mature. Hay containing Lupines is wholesome if it contains no ripe seeds. The perennial roots may be destroyed by cultivation of the land, which should be put to a well-fertilized and well-tilled hoed crop before reseeding with clover or NEBRASKA. LUPINE Lupinus plaitinsis, S. Wats. Native. Perennial. Propagates by seeds and by rootstoeks. Time of bloom: June to July. Seed-time: July to August. Range: Nebraska, Wyoming, and the Dakotas. Habitat: Plains; pastures and meadows. Lupines furnish western stockmen with much nutritious green forage and good hay. They are especially valuable in the late fall,.
