I. SOME seedlings of the Sunflower should be bedded 

 out, and allowed to grow for about three months : ex- 

 amine a well-grown specimen of that age, as a whole. 

 The main axis or stem is stout, herbaceous, and erect : 

 it often develops to a considerable length without 

 branching : it is cylindrical, slightly striated below, 

 while the higher parts of it, where the lateral branches 

 are developed, are polygonal. Its surface is studded by 

 stiff hairs, which are especially obvious on the lower 

 portions of the internodes. 



The stem bears laterally numerous leaves, which 

 are simple, petiolate, 1 cordate-acuminate, the margin 

 slightly serrate, ciliated, venation palmate-reticulate, 



1 N.B. The form of the leaves varies, the lower leaves of the plant 

 being cordate, the upper ones lanceolate with winged petiole.
