Violet scarcely touches blue. The pealike blos-

 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.

Stone Clover na " v from Europe, remarkable for its 

 Tri folium 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-

 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

Tri folium special favorite of the bumblebee upon 



pratense whom it is almost wholly dependent for 



Crimson or fertilization. The plant was introduced 

 Ma^s* 3 int Australia some years ago and. failed 



be * y ~ " to produce seed the first year through its 



separation from the Ainerican 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
