interactive keys and others

[Heike Vibrans]

I was wondering (and it would be important for my own
work):

Are there any quantitative data or publications out there
on the relative merits of different ways of identifying
plants (perhaps comparing conventional keys, interactive
keys and flower-color-sorted pictures, as in many popular
field guides)? In terms of % correct identifications and
time necessary? Perhaps even distinguishing between
trained botanists and laypeople?

Regards,

Heike
