This is the second volume in a developing series on leaf venation patterns of plants. The first volume dealt with the Annonaceae and this one deals with the Lauraceae. Both of these families are large, composed almost entirely of woody plants, are largely tropical in distribution and have leaves with entire margins. For each volume, the leaves of 20 to 25% of the species making up the families were cleared and photographed. These leaves were used to characterize the leaf venation patterns of the genera of the family. The purpose of characterizing the venation patterns of plant genera is to establish a catalog of venation patterns which can be used to help identify fossil leaf impressions and herbarium specimens and might also help to determine relationships between various plant taxa.
