I have been hoping for this follow-up; I had started to believe the first paper was a hoax because it’s so outlandishly “sci-fi” for a plant to do this.

Obviously plants are photosensitive, so it’s not an impossible leap - my conjectured hypothesis was it somehow detected the adjacent leaf imprint on its own leaves and cropped them to fit the template. But how that information would be carried over to nearby leaves for any sort of consistent match is beyond me.
