Chapman's Pea (Genus Chapmania) 



This interesting plant of upright growth is common in 

 dry soil, beginning to bloom in late winter, and bearing 

 fragile yellow flowers along the leafless upper part of 

 the stem, which is sticky with gland-tipped hairs on which 

 small insects are caught. The flowers open early in the 

 morning, but close before ten o'clock when the weather 

 is warm. The somewhat similar wings and standard spread 

 widely and give the flowers a three-petaled appearance, 

 as the keel is small. Besides these sho\vy flowers, which 

 form no seeds, there are inconspicuous fertile flowers with- 

 out petals. 



The seedpods of this and the five following genera dif- 

 fer from those of our other peas as they are formed of 

 joints that separate readily from one another. 



The generic name of this plant honors Dr. Alvan Went- 

 worth Chapman, whose admirable "Flora of the Southern 

 United States" was for many years the standard manual 

 of southern wild flowers.

 yellow, with dark spot on standard, few, in axiflary racemes.
