Botanical Keys - Find Wild Flowers

The Botanical Society for Britian and Ireland (BSBI) hosts this on line plant key produced by one of their members. There is a simple questionnaire on the characteristics of the plant you are trying to identify and on completing the questions and pressing press search, the computer will present some feasible options. It can also be used to obtain a check-list of plants from a particular habitat or perhaps find flowers of a particular colour to grow in your garden.
