Osteospermum yellow, a bunch of flowers wrapped in petals.
Big sunshine yellow ray florets, ring an array of disc florets on day 1. It takes another 7 days before the secrets of this flower are fully revealed.
Hippeastrum Anthers, a closer look.
Anthers were the sticky-up yellow powdery things that released pollen to insects and the wind. This model worked well through 40 years of science teaching. Biology was a sideshow; chemistry and the wonders of the Periodic Table was my area of expertise.
How pollen emerges from its anther is a wonder to behold. Just a pity it took 70-plus years before I witnessed it.
