Description
- Title:
- Small cactus flower [UV]
- Caption / Description:
-
Ultraviolet photograph of the flower of a small cactus (possibly a Mammillaria elongata cultivar).
The flower's appearance in ultraviolet is quite different to that in visible light. The petals appear much darker, making the flower stand out from the white spines covering the cactus. The anthers and pollen also appear much darker in UV, compared to a light yellow colour in visible light.
The rest of the cactus appears quite similar in UV to how it normally appears to the eye. The stem is quite dark, covered in white spines. Around the top of the large stem bearing the flower are some longer darker spines.
