They describe vegetation types which we have seen during our surveys in Britain and Ireland but which are not included in the NVC or which can be classed as particular distinctive forms of existing NVC communities or sub-communities. The descriptions that follow are based on our own observations except where acknowledged. Also included here are a few vegetation types that are floristically intermediate between two NVC communities. NVC intermediates are so numerous and so common that an attempt to describe all of them would cause great complexity and confusion. They can often be recognized fairly easily anyway, and classified as such (for example U4-U5 or M15a-c). However, a few NVC intermediates are included here because they are particularly common, extensive or distinctive. Vegetation types restricted to extremely narrow or linear strips such as that between a roadside verge and the base of an adjacent hedge or wall are not included. There is something of a northern/upland bias to the vegetation types described here.
