PULSE FAMILY. Legumlnosm. 



This is one of our most charming so- 

 Lupinus called blue wild flowers ; but it rings all 



perennis the changes on violet and purple, and 



Violet scarcely touches- blue. The pealike bios- 



May-June gom j iag violet or deep purple wings and 



a light violet hood veined with blue-violet. Rarely the 

 sweet-scented flowers are magenta-pink or even white. 

 The horse-chestnutlike leaf has generally eight narrow, 

 light green leaflets. Stem and long-stalked leaves are 

 generally fine-hairy, and frequently show a few touches 

 of purple-red through the green. The flower-spike is 

 quite showy, and pinkish early in the bud. Fertilized 

 by bees. 1-2 feet high. In sandy fields everywhere. 



A naturalized species of clover, origi- 

 Rabbit-foot or ... w i ui \ -^ 



Stone Clover n &"y from Europe, remarkable for its 

 Trifolium oblong fuzzy flower-heads, the corolla of 



arvense which is green-white and the calyx green 



Gray-pink with pink tips, all in effect rather gray- 

 s u ^ us . pink. The light green triple leaves have 



narrow, long leaflets with blunt tips. The 

 flowers are sweet-scented. 4-10 inches high. Common 

 in poor soil, old fields, and pastures, everywhere 



This is our commonest field clover and a 

 Trifolium special favorite of the bumblebee upon 



pratvns, whom it is almost wholly dependent for 



Crimson or fertilization. The plant was introduced 

 magenta mto Australia some years ago and failed 



ber " to produce seed the first year through its 



separation from the American bumblebee. 

 Later when the insect was transported the plants flour- 

 ished from season to season. The three (rarely 4-5) 

 rather soft, dull bluish green leaflets are conspicuously 

 marked by a whitish or yellow-green triangle. There 

 are two hairy white and green stipules or leafy wings at 

 the base of the leaf-stalk. Stem and leaves are soft- 

 hairy. The somewhat pyramidal globular flower-head 

 ranges through crimson or magenta to paler tints of the 

 same colors, and even white ; it yields a plentiful supply 

 of nectar, which is scarcely reached by the short tongues 

 of honeybees ; also, the butterflies are not sufficiently 

 heavy to depress the keel of the floret and thus expose
