A Difficult Flower to Cross-Pollenize 



To casual inspection, the iris does not appear to be a 

 perfect flower. That is to say, it seems to lack stamens and 

 pistils of the ordinary type. In point of fact, the iris has organs of 

 fertilization that are quite petal-like in appearance, arranged 

 in such a manner as to provide against self-fertiliza- 

 tion. But intelligent inspection will enable 

 the would-be pollenizer to solve 

 their mysteries without great 

 difficulty.
