Definitions of terms used
in Flower Descriptions above:

|
Radial Symmetry: - capable of being divided into two equal-appearing halves along more than one lengthwise plane. |
Bilateral Symmetry: - capable of being divided into two equal-appearing halves only by a single lengthwise plane passing through the axis. |
Tubular: - shaped in a tube or funnel shape. |
Not-Tubular: - not shaped in a tube or funnel shape. |
