Species.—It is not necessary for one to be a botanist in order to recognize, during a stroll in the woods where the tril- lium is flowering, that there are many individual plants very like each other. They may vary in size, and the parts may differ a little in form. When the flowers first open they are usually white, and in age they generally become pinkish.

They may vary in size, and the parts may differ a little in form. When the flowers first open they are usually white, and in age they generally become pinkish. In some in- dividuals they are pinkish when they first open. Even with these variations, which are trifling in comparison with the points of close agreement, we recog- nize the individuals to be of the same kind, just as we recognize the corn plants grown from the seed of an ear of- corn as of the same kind. Individuals of the same kind, in this sense, form a species. The white wake-robin, then, is a species. 251. Fig. 324.
