Look at a Flower.

Everyone is interested to some extent in the flowers that grow around
him; and, though many people are probably satisfied when they
have learned to tell a rose from a buttercup, those who really
love plants soon see more than the pretty posy and become aware
of beautiful and significant structures within it.
Though this volume can be used as a foundation for serious
botanical study, its purpose is achieved if it stimulates the reader
into his own investigations and directs him to friendships with
living plants in their everyday surroundings. It is intended as
a guide to plant watching and an introduction to the tiny floral
arenas where things are always happening. And it should lead
both student and dabbler beyond the larger shapes of a flower
into the wonder of form and the beauty of design in its small
and often hidden parts.
