Plant-Breeding 



jecting over the stigma is a greenish ladle-like body, T, 

 which is a transformed and ^sterile anther. In all lady- 

 slippers, these organs are essentially the same as in the 

 drawing, although they vary much in size and shape ; 

 but in most other orchids, the two side anthers, S, are 



wholly wanting, 

 and the terminal 

 organ, T, is a 

 pollen-bearing 

 anther. In nu- 

 merous plants, 

 there are many 

 distinct pistils 

 in each flower. 

 Such is the case 

 in the straw- 

 berry, where 

 each little yellow 

 "seed" on the 

 ripened berry 

 represents a pis- 

 til ; and the 

 blackberry and 

 the raspberry, 

 where each little grain or drupelet of the fruit stands 

 for the same organ. A flowering raspberry is illustrated 

 natural size in Fig. 86, for the purpose of showing the 

 ring of many anthers near the center of the flower, inside 

 of which, in the very center, is a little head of pistils. 



It frequently occurs that the stamens and pistils are 

 borne in different flowers, rather than together in the 



FIG. 86. Blossom of flowering raspberry 

 (Rubus odoratus).
