The implementation of intelligent systems is not particularly widespread in the field of Botany and even less so on Internet.

GREEN is an Expert System for the identification of Iberian Gymnosperms which allows online queries to be made. It can be consulted in: http://drimys.ugr.es/experto/index.html
