Ste CookThis is supposed to be a spiky fluffy inflorescence but the stem on which the little flowers grow is weirdly flattened and then overgrows sideways in way that looks like it’s trying to explore hyperbolic space. Celosia argentea - cristate mutant.

Khurram Wadee ✅You can also explore #non-Euclidean space and here is the same action in #HyperbolicSpace (here in a #PoincaréDisc). #StraightLines are replaced by #GeodesicLines which look like #CircularArcs which intersect the #disc at #RightAngles. Circles are transformed to circles but their hyperbolic centres are not at their Euclidean centres.
Repeating the construction for Euclidean space, you can see that the parallel lines diverge.
