*'The wild species include some that are white in color as 

 well as those that are pink or white striped with pink or 

 with reddish veins. So there is opportunity to have a wide 

 ^ choice as to color variation. The cross might likely result 

 I also in giving the geraniums enhanced vigor^ so that new 

 graces of perpetual bloomers would be produced." 



;■: (Vol. VII, p. 182-184) 



''The Practical Essentials of Hand Pollenizing" (See 

 pages 5-6), gives the details of the simple, yet practical^ 

 methods by which hybridizing is accomplished. The dia- 

 gram below shows the construction of the geranium, and 

 should be of further assistance in your work. It remains 

 only for you to apply these methods to the geraniums you 

 have chosen for your experiment. 



(A) Inflorescence of a geranium; 

 open flower on left showing con- 

 dition with mature anthers and 

 immature pistil; open flower on 

 right showing condition with 

 mature pistil and faded (de- 

 funct) anthers. 



(B) Stamens and pistil from lefr- 

 hand flower, enlarged. 



(C) Pistil with stamens removed, 

 enlarged. 



(D) Mature stamen, enlarged. 



(E) Mature pistil showing ovary, rJ- 

 ways included in stamen-tube, 

 style, and radiating stigmas, 

 enlarged. 



Few plants among all the popular favorites have 

 greater merits than the geraniums, and none per- 

 haps offers better opportunities for interesting 

 experiments that may be made by the amateur.
