In hazel (Fig. 29) the male and female flowers

 little like the regular types with which we are 

 familiar; yet intermediate cases help to bridge 

 over the gap for us. 



For example, in the alder we get a type which 

 seems to stand half-way between the nettle and 

 the hazel (so far, I mean, as the arrangement of 

 the flower is concerned, for otherwise the nettle
