The Department of Biology of the University of Trieste is creating a
series of interactive keys for the identification of vascular plants
from different areas of Northern Italy. The keys, produced by program
FRIDA, patented by the University of Trieste, are illustrated with
thousands of original pictures. Although they written in Italian, they
may be of interest also outside the country, since most characters are
illustrated by drawings and pictures. The hitherto available keys are
accessible from:
