This is hilarious. Most of these L-systems generate "morphic words", https://en.wikipedia.org/wiki/Morphic_word, a kind of L-system I have a particular affection for, because it seems to me like the simplest kind of aperiodic sequence.
As a fascinating coincidence, it was specifically thanks to Mark Dominus that I was fiddling with L-systems on Monday, even though I was not yet aware of this article. I wanted plant models that were a little more stochastic and expressive than bare L-systems, but less verbose and clunky than the CGA shape grammars used in CityEngine. Claude suggested parameterizing Chris Coyne's "context-free design grammars", giving very pleasing results like
# A monopodial tree: every node puts out one lateral and the axis carries
# on at `ratio` scale, so the laterals shrink, and crowd together, in the
# same geometric progression toward the tip.
param ratio = 0.9 in 0.7..0.97
param lateral = 0.5 in 0.2..0.8
param spread = 50 in 0..90
param divergence = 137.5 in 0..180
param droop = 6 in -20..30
start shoot
shoot when size < 0.03: leaf 6 3
shoot:
limb 1 0.09

> I tried to get Claude to help me with this article, but it said the premise was too stupid so I had to do it myself.
Let that be a warning to the rest of you.
I love this haha
