 ties. The market for these plants is of course 

 restricted at best. 



A more tangible property, and one that is 

 likely to appeal to the user of the plant, is the 

 shape and quality of the leaves. I have worked 

 on the curled parsley to some extent and have 

 found that by careful selection it can be im- 

 proved greatly in a short time. The different 

 tendencies of the leaves can be fixed quite readily 

 in three or four generations. 



I had also developed a golden-leaved parsley,

 was a plant of great promise and I expected to 

 introduce it. But to my regret, it was destroyed 

 by millipeds just before it was ready to produce

Another genus of the parsley family, Ligusti-

 several California species in the northern and
