General Structure.—You have already learned (page 59) the names of what may be called the " principal parts " of flowers.

Some flowers are composed of essential parts only. The familiar wild flowers are composed of both essential and accessory parts. The puter, conspicu- ous parts are the accessory ones; the inner, incon- spicuous parts are the essential ones.
