The Micrographic Dictionary—Pollen Grains

Abstract

I READ your criticism of this book in last number of NATURE with a good deal of interest, and I fully agree with your reviewer in his statement that “workers in different fields will place a different estimate on the importance of their own department.” Allow me to call your attention to the two singularly erroneous figures of the pollen grains of Mimulns moschatus (Pl. 32, Fig. 24) in this work. I have frequently examined the pollen of this plant, and have never seen it anything like the figures in the “Dictionary,” or in any way differing from the grains of many other members of the Scrophulariacese. The pollen of M. moschatus is like a grain of wheat, and not like the wonderful convolute ball shown in the “Dictionary.”
