38 PLANTS OF MASSACHUSETTS. 



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. 



A. falcata, Mx., which is A. Canadensis, L., is named from 

 the shape of its pod, flat and curved like a scythe, and called 

 Sicklepod. Stem 2 or more feet high, round and small, with 

 sessile leaves ; flowers in woods, in June. 



A. rhomboidea. Ph., has fine rhomboid leaves on the stem, 

 and heart-shaped ones at the root ; flowers white ; grows on wet 

 meadows, Roxbury. Blossoms in May ; root tuberous and fari-

A. thaliana. L. Wall Cress ; is a small plant about six 

 inches high, branched ; radical leaves on petioles ; stem leaves 

 sessile and few ; flowers white in a corymb ; on hills, and blos- 

 soms in May. 



Of the other species, A. hirsuta, Sm., there is some doubt, 

 which cannot be solved at present.
