large bunch of small white or sometimes red flowers. It is 

 used in many places as an application to fresh wounds, which it 

 much assists in healing. It is common in all meadows. 



" Green Yarrow ! nature's simplest child, 



Thy leaves of emerald green, 

 And silvery blossom undefiled, 

 In rugged path or barren wild. 



The traveller passes by. 

 With reckless glance and careless tread 

 Nor marks the kindly carpet spread, 



Beneath his thankless feet. 

 So poor a meed of sympathy, 

 Do gracious herbs of low degree, 



From haughty mortals meet." Strickland. 



O. S. Downy Yellow Yarrow, a plant of the mountains of Ireland, and 

 grown in the gardens as Golden Yarrow. 



KNAPWEED, &c. CENTAUREA. 

 BLACK KNAPWEED. Centaur ea nigra. 



Plate 13, fig. 14. 

 Leaves cleft. Flowers small, purple. Calyx scales black. 



This grows over pastures and meadows very frequently. It 

 is a very troublesome weed, commonly called Hard-hack, on 

 account of its toughness, and blunting the mower's scythe so 

 much where it abounds. The calyx is of many blunt, black 

 scales, fringed with teeth, and lapped over each other, and the 

 flowers all small, pink, and tubular thus the heads of flowers 

 appear like thistles. The leaves are without thorns, the lower 

 ones lyrate, upper ones not so much cleft. It flowers in the 

 hay season, and grows two feet high. 



CORN BLUE -BOTTLE. Centaur ea Cyanus. 



, Plate 13, fig. 15. 

 Leaves linear, entire. Flowers blue. Calyx green. 



A plant in every respect different from the last, that was 

 inelegant, this is beautiful. It is abundant in corn fields, 

 flowering all the Summer, and when its fine, large blue flowers 

 are seen in contrast with the scarlet Poppy, and the green or 

 golden Corn, it forms the finest object. 



" The blue Cyanus we'll not forget, 

 'Tis the gem of the harvest coronet."
