||[no title-caption in lower margin]
Each supplemental set design is based upon at least one of the designs in the primary series.
It consists of two basic parts, the background image and an overlay image.
Occasionally, the background image may be enhanced with highlights included on the overlay plates,
and here the third color is used on both images.
For wfx4, the silhouette of wf7 was used as the background image.
Typically for the supplemental set, the overlay image for wfx4 shows a species represented in another design in this series,
but in an entirely new composition.
Background: Amaryllis, Hippeastrum
Overlay: Nasturtium, Tropoleum cultivar
