Abstract

A new method for the description of leaf shape is presented, based on an interactive computer program for describing rosette leaves of Chondrilla juncea. In addition to the usual measures of length, breadth and area an alternative description is provided based on a coding of the boundaries of the leaves. The efficiency of the machine-assisted description is assessed and a comparison of the alternative descriptions provided.
