Does anyone know a gizmo that will identify plants from a photo?

Compared with other things that have been developed - e.g. to
distinguish between two twin brothers - distinguishing between plant
species seems rather easy, yet I cannot find any such thing referred
to on the web.


Posting a request on here with a link to a clear photograph on a site
such flickr seems to work quite well for most things.

Whilst there are some useful image libraries online and of course
Google, I am not aware of an image ID matching application. For wild
plants I have used this site for some years -
http://www.botanicalkeys.co.uk/flora/content/SEARCH.ASP - which
requires some thought and input but has proved quite useful.
