Glomerules difler from heads in the same way. The woodland flowers Trillium and* Anemone furnish examples ofthe simplest form of Terminal Inflorescence. Their simple stems be^reach one flower at the top. Often flowers seem to be axillary when theplan of inflorescence is terminal. Fig. 57 illustrates a case of this INTRODUCTORY LESSONS.

Imagine the plantshown in Fig. 57 to continue branch-ing, the stem to be shortened so as tobring the flowers close together, andthe leaves to become obsolete.
