The Botanical Garden’s DNA Bank is a centralized repository of frozen plant, algal, and fungal tissue and extracted DNA (a self-replicating material that is the carrier of genetic information) for use in analyzing plants at their most essential levels. DNA Bank collections are a primary resource for research carried out in the Garden’s Lewis B. and Dorothy Cullman Program for Molecular Systematics and Genomics Program. Extracted DNA and tissue collections of the DNA Bank are authoritatively identified, properly documented, cross-referenced to specimens in the Garden’s William and Lynda Steere Herbarium and other herbaria, and managed on the model of traditional museum collections.
Searches in the DNA Bank are word-based by default. The fastest searches are made by using whole words as the criteria. Wildcard characters can be used to find partial words, but search times will be significantly longer.
Use an asterisk (*) as a substitute for any number of characters in a word. (Example: "South*" in the Province/State field will return specimen records from "South Dakota," "South Carolina," etc.)
Use an exclamation mark before a word to specifically exclude that word from the search. (Example: "Panicum" in the Genus field and "!diffusum" in the Species field will return all records of Panicum exceptPanicum diffusum.)
Use quotation marks to search for exact phrases. Words not enclosed by quotation marks will be used to search for records with all of the words, but not necessarily in the order typed.
*The Scientific Name field can be used to search by the genus, species, infraspecies, and author abbreviations of a name.
Example 1: the search term "viridis" finds specimens of Rauvolfia viridis , Amaranthus viridis, etc.
Example 2: the term "Ekman" finds specimen records of numerous taxa described by Erik Ekman.
Many of our records from rapid digitization projects will only have a family, scientific name, barcode number and image available at this time. Please limit your searches to these fields to maximize your query results.
In an effort to meet our obligation to protect populations of endangered species from over-collection, some of our specimen data (such as specific locality information) have been removed from those online records for endangered species. These data are made available to researchers on request. We are aware that making our herbarium specimen data available involves striking a delicate balance between access to data that are important to research and the potentially reckless posting of sensitive information. To that end, we have removed specific locality information for Appendix 1 species listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
