Summary Taxonomists generally recognize the value of collection dates in planning biosystematic research but do not always appreciate their usefulness in documenting migrations and introductions. A survey of several journals shows that many taxonomists fail to include collection dates in monographs and other taxonomic treatises. Correlation of collection dates for a particular taxon with dates of general botanical collecting in a particular locality has been used to document an eastward migration of *** Dyssodia tenuiloba (DC) Rob. in Texas and the introduction of Thelypteris dentata (Forssk.) E. St. John into the New World.
