sidedness-map

Each row is one wrecked cut. The centre line is the azimuth the next organ would have taken; the two open marks are where the two contact families leave it, which are always on opposite sides because that is what makes them the two nearest neighbours of a lattice point. The filled mark is the organ that was removed. Reading the lost-member rule as a question about which side rather than about which chain makes it answerable on all 30 cuts instead of 9, reproduces the published reading on every one of those 9, and is right on 22 of 30 overall.

Drawn at its defaults, in the reference a wrecked stem does not have. It takes no options at all, so every essay calling it gets this exact drawing.

What a plant might be doing

Removing a neighbour costs least

Take away an organ that is a direct chain-neighbour of the growing tip and the next organ moves by under thirty-one degrees. Take away anything else inside the front and it moves by at least sixty-three. Thirty cuts, two groups, a factor of two between them and nothing in the gap.

Where the angle comes from

The organ that moved furthest

A reading that works on nine of thirty rows needs a reference organ, and the obvious repair is to measure one rather than to choose it. Measured, the disturbance turns out to have no far edge at all, so there is no organ that moved furthest in any sense the reading can use — and the generalisation that does work needs no reference organ.
