# On the Various Contrivances by which British and Foreign Orchids are Fertilised (1862) is a dated botanical-network treatise

Date: 1862

## The fact

In 1862 the orchid fertilisation treatise was published as a dated botanical-network book. The instrument is that treatise, not Origin as a duplicate and not a later flower show. Charles Darwin's documented role is: He wrote the orchid book from correspondence and experiments. Gardeners and Hooker sit in the network. This is not Origin chapter-split.

## Context

Hooker and unnamed gardeners share the network. Sharing them is required. The setting of On the Various Contrivances by which British and Foreign Orchids are Fertilised (1862) is a dated botanical-network treatise is the public file around 1862-01-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [social-cohesion](/drivers/social-cohesion) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

The attached driver is social-cohesion. The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.

Naming Charles Darwin does not delete co-authors, institutions, or later transmitters. The lag from 1862-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
