Helianthus. L. 17. 3. Sunflower. 



Named from the Greek for sun and flower, on the popular no- 

 tion, that the flowers of the great Sunflower turn towards the sun, 

 and partially follow it, for which there may be some little founda- 

 tion ; but especially from the size and appearance of that large 

 and fine flower, the ray florets round the broad disk being an apt 

 resemblance of the radiating appearance of the border of the sun, 

 as the broad and glowing face of the " powerful king of day" 

 comes " rejoicing in the east." This genus belongs almost ex- 

 clusively to North and South America, and contains about 30 

 species, of which 12 are natives of the Middle and Northern 

 States, and 5 are found in this State, 3 only being indigenous. 

 They add considerably to the beauty of the woods and hedges in 

 the autumn, though their fine yellow-rayed flowers are not very 

 large. 



More than 20 species, introduced from America, have been 

 raised in England. 



H. trachelifolius. W. Wild Sunflower. This is the common 

 sunflower of the woods and hedges ; stem 3-4 feet high, branch- 

 ing towards the summit, roughish ; leaves ovate-lanceolate, ser- 

 rate, 3-nerved, tapering into a short petiole ; August to October.
