Variations 'built-in'

Creat,
Andrographics paniculata
It was a hot
Sunday afternoon
- I decided to take a
closer look of the flowers
of 'chuan shan lian' - a medicinal plant ...

While the main centra 'ink-blot' patterns
mirror each other
there are variations of
the side petals
( Left to right swap
and streaks differences)
