A beautiful blossom, flaunting a large banner out of all propor- 

 tion to the size of its other parts, that it may arrest the attention of 

 its benefactors the bees. According to Henderson, the plant, 

 which is found in our Southern States and over the Mexican border, 

 grows also in the Khasia Mountains of India, but in no intervening 

 place. Several members of the tropic-loving genus, that produce 

 large, highly colored flowers, have been introduced to American

 shut up, in reference to the habit these peas have of seeding long 

 before the flower drops off.
