Original research: the Gini coefficient

The “Inequality” section applies an economic measure to a plant. No published source calculates a Gini coefficient for the umbels of giant hogweed, so this is original research, and the comparison with countries is plainly an attempt to make a point. Tagged. — InvisibleHand (talk) 14:14, 25 September 2026 (UTC)

The data are Perglová et al. (2006, 2007); the method is Weiner & Solbrig (1984), who took it from economics because it measures exactly this. Anyone can check the arithmetic: one umbel in 28 sets nearly half the seed. A routine calculation is not original research. — Moor (talk) 15:03, 25 September 2026 (UTC)

The terminal umbel is the largest. It has earned its share. — InvisibleHand (talk) 15:20, 25 September 2026 (UTC)

It opens first and is first in line for everything the leaves and the root have stored. Its size is a matter of position. — Rosa L. (talk) 15:48, 25 September 2026 (UTC)

Note also that the quaternary umbels, which set no seed at all, appear in the source as “pollen donors”. Their pollen ends up in seed that is counted to other umbels. — Old Mole (talk) 16:05, 25 September 2026 (UTC)

Compromise: keep the calculation and the tag, drop the countries? — Kingfisher (talk) 17:30, 25 September 2026 (UTC)

The countries stay. Readers can decide for themselves which is the more unequal. — Rosa L. (talk) 18:12, 25 September 2026 (UTC)

Why not keep 100,000?

The following discussion has been closed. The article gives the measured figures.

Surely the exact figure does not matter. “Up to 100,000 seeds” is a useful round number for warning the public, and every leaflet uses it. — Ed. Bernstein (talk) 10:00, 12 August 2025 (UTC)

The seed bank is fed by seeds, not by round numbers. Twenty thousand real ones are quite enough; there is no need to count the male flowers twice. — Old Mole (talk) 11:31, 12 August 2025 (UTC)
