The number of petals a flower has can be an important key to identifying the flower.
Newcombe's Wildflower Guide is based on this concept.
An important thing to remember about this concept is that the "number of petals" represents the number of apparent petals.
This is not necessarily the botanically-correct number of petals. Oftentimes what appear to be petals are actually sepals or bracts.
It is an aid to identification, not a botanical classification. | | |
