TOLEDO AND M. SOTO 50 collection numbers. It was evident that the herbarium at the Museum of Natural History at Paris is of high priority for our research. One problem in maintaining an up-to-date file is that any change in the determinations of Veracruz specimens has to be communicated to us. We trust that most of the corrections will be made through specialists workingforourprogramme. If this is carried out the problem of updating does not exist. Another possibility is that when monographers change the names of specimens, we wait until the paper (monograph or revision) is published to capture the corrections.

Three years ago several projects were started to capture data from specimens in selected large herbaria with the objective of evaluating the quality and quantity of Veracruz collections in those herbaria. At the same time we have captured the label data for the Flora of Veracruz data bank. We have surveyed the following herbaria for this purpose: Arnold Arboretum, Gray, the Royal Botanic Gardens, Kew and the National Herbarium of the University of Mexico. In addition, we have made a sample survey of two families (Araliaceae & Piperaceae) in a larger number of herbaria: Leiden, Utrecht, Paris, Florence, Vienna Museum, British Museum, (Natural History), Missouri Botanical Garden, Field Museum, and Madrid.
