400 million years of separation

Glad to be alive? Thank a plant today.

The oxygen you breathe, the food you eat and the fuel you burn all came from plants. Any plant to thank in particular? Well, a good start would be Selaginella, the Platypus of the Plant Kingdom. It’s a relative of all flowering plants but has no direct descendants – it’s a survivor that’s an evolutionary blind end – apart from the 700 or so species worldwide. When was the last time you looked at a piece of coal? It is the fossilised ancestors of Selaginella. Selaginella was one of the first plants to develop a system of tubes that transport water and nutrients inside a plant, one of the most important developments in evolution, allowing large plants to evolve.

Selaginella
At the top of Fitty Hill grow living fossils – Selaginella selaginoides – plants which aren’t flowing plants, which aren’t ferns, which aren’t mosses. They’re survivors, separated by 400 million years of evolution.
The common name ‘Lesser Clubmoss’ really doesn’t do them justice.

The iron sheets holding the concrete protection for the Orkney Ferries terminal at Rapness are beautiful in this light.
