PLANTS FOR EXPERIMENT 191 



white plume had been produced through artificial 

 selection, and therefore its characters were not as 

 well fixed as in the wild type. 



An interesting feature of this experiment was 

 that the pink color seemed to appear oftenest on 

 the staminate plants and not on those that bore 

 both stamens and pistils. 



This gives a suggestion of the element of sex 

 selection in heredity, which is seldom observed 

 in plants, although common enough among 

 animals. A further evidence of this was seen 

 in the fact that I was never able to fix the 

 color so thoroughly on the female plants as on 

 the male. 



The pampas grass is multiplied by division, so 

 that there is no difficulty about the multiplica- 

 tion of a new variety. The new varieties do not 

 usually come true from seed. But this is of no 

 importance, inasmuch as a single plant may be 1 

 so multiplied by division as to produce probably 

 fifty thousand marketable plants, on good soil, 

 in the course of two or three years. 



SOME MISCELLANEOUS IMPROVEMENTS 



From among a great variety of experiments 

 looking to the improvement of farm and forage 

 crops, I will select only three or four additional 

 ones as offering further suggestions.
