D. laciniata. W. Stem is scarcely as high as the other, and 

 sends off 3 ternate leaves, or 3 leaves divided into 3 segments, 

 linear, and somewhat toothed, with reddish white flowers in a 

 raceme ; grows in woods, and flowers in May. 



Both these are rather beautiful plants. 



LUNARIA. L. 14. 1. 



Two species are cultivated for their flowers ; one bears its fruit 

 in a flat, oval, or roundish pod, of singular appearance, and an 

 inch in diameter ; flowers bluish and purple. 



Iberis. L. 14. 1. Candy Tuft. 



A species with whitish flowers has been long cultivated as edg- 

 ing for aisles in gardens and walks. Another beautiful variety, 

 with purple flowers, is becoming common. Native of Spain, 

 Tuscany, &c. So called from Iberia, the ancient name of Spain. 



Arabis. L. 14. 2. 



Five species are credited to this State.
