The grammar
Each species here is not a drawing but a recipe — a few dozen rules about how far a stem may reach before it considers branching, how steeply a branch may depart, how leaves take turns along the stem, and when a tip has earned the right to flower. The machine follows the recipe the way ivy follows a wall: locally, stubbornly, beautifully. Botanists call the idea an L-system, after Aristid Lindenmayer, who noticed in 1968 that plants are grammars you can read.
ii.
The seed
Every specimen begins as one number. That number feeds a chain of dice rolls, each decided entirely by the one before it — so № 48213 grows the same plant tonight, next year, on your machine or mine. Randomness with a memory is just fate with better manners. Write down the numbers of the plants you love; they will keep.

The ink
There are no images on this page. Stems are ribbons of canvas geometry, leaves are two bézier curves apiece, and the paper’s fibre is turbulence — a pair of SVG filters written character by character into their own web addresses. If it reads as pressed and kept, that is only mathematics wearing its Sunday clothes.
