Family 59. KRAMERIACEAE Dumort. Anal. Fam. 20. 1829. 



Krameria Family. 

 Pubescent herbs, or low shrubs, with ahernate simple or digitately 3-foliolate 

 leaves, and purple or purplish, solitary or racemed, irregular perfect flowers. 

 Peduncles 2-bracted at or above the middle. Stipules wanting. Sepals 4 or 5, 

 usually large, the outer one commonly wider than the others. Petals usually 5, 

 smaller than the sepals, the 3 upper ones long-clawed, often united by their claws, 

 or the middle one of tiie 3 wanting, the 2 lower ones reduced to suborbicular fleshy 

 glands. Stamens 3 or 4, monadelphous, at least at the base : anther-sacs opening 

 by a terminal pore. Ovary i-celled, or partly 2-celled ; ovules 2, collateral, anatro- 

 pous, pendulous ; style slender, acute or truncate. Fruit globose, or compressed, 

 spiny, indehiscent, i-seeded. Seed without endosperm; cotyledons fleshy. 



The family consists of only the following genus, with about 20 species, distributed from the 

 southern United States to Chile. It has often been included in the Polvgalaceae, but its affinity 

 to Cassia and related genera indicates that it should be placed next to the Caesalpiniaceae.
