BBC - Earth News: "Plants may be able to recognise themselves.

Experiments show that a sagebrush plant can recognise a genetically identical cutting growing nearby.

The findings, published in Ecology Letters, raise the tantalising possibility that plants, just like animals, often prefer to help their relatives over unrelated individuals."
