Oxalis tetraphylla (Four-leaved Pink Sorrel) Vis UV IR comparison

Oxalis tetraphylla (Four-leaved Pink Sorrel) Vis UV IR comparison
Oxalis tetraphylla (Four-leaved Pink Sorrel) photographed in visible light (top), ultraviolet light (middle), and infrared light (bottom).

In visible light the plant has pink flowers with a green centre. The flowers are quite strongly veined, with the veins leading in towards the centre of the flower. The leaves appear green with a darker, red-green coloured area at the base of each leaf.

In ultraviolet light the centres of the flowers are quite bright, with a much darker centre. The veining present in visible light is also visible in ultraviolet. The leaves are a single tone.

In infrared light the flowers have little variation in tone. The same veining present in visible and ultraviolet light is visible, but only just. The leaves are a single tone, and also appear brighter than they do in visible or UV light.
