The analogy between these full-grown plants of an exceedingly 

 low grade and the pollen-grains (Fig. 115) of *a rose, standing at 

 or near the head of the plant kingdom, is at once apparent. They 

 contain particles (fovilla) destined to the same office of reproduc- 

 tion ; one woodcut serves to represent both.
