THREE LEAVES FROM A SINGLE PLANT 



The wide variation shown in the characteristics of the artichoke is strikingly brought out by 

 the above photograph of three leaves from a j)lant growing in the \'ictoria bridge gardens 

 at Riverside, Cal. The fact that i)lants vary has always been recognized in a theoretical 

 way, but many horticulturists have overlooked the fact that these variations possess 

 great commercial importance. (Fig. 10.) 



out as most strikinj^ in the i)rcliminar\' 

 study thus far given these plants. 



The plants of one of the strains 

 produce flower heads having a globular 

 shape. The leaves of these jolants are 

 usually ])innatilol)ed. The ])lants of 

 the other strain bear rather elongated 

 flower heads, making them somewhat 

 cylindrical in shape. The leav2s of 

 these i^lants are usually ])innatifid. 

 Photographs showing the typical flower 

 heads and leaves of the y)lants of these 

 strains arc shown in Fig. 9.

Inasmuch as llie ])lants in this 

 garden have all been i)ro])agate(l asex- 

 ually, from ofi"sets or suckers, largely 

 from one jjarent ])lant, it is but logical 

 to conclucle that the variability of the 

 ])lants is due to bud varialion . The 

 suckers were detached from the i)arent 

 plant in the s])ring before growth began. 

 The writer hoj^es to be able to secure 

 some selection of suckers from ])articu1ar 

 l)lants with a view to isolating the 

 several strains represented in this fleld.
