Catalog of Bryophytes

The L.E. Anderson Bryophyte Herbarium now provides a major portion of the herbarium specimen records online. The online catalog is updated biweekly. Cataloging the Southeast US specimens has been completed and cataloging of all North American specimens is well under way. Specimens from other parts of the world have been cataloged when used for scientific research, or on loan. All new accessions into the collection have been cataloged since 2000.

Specify 6 is used for managing the bryophyte catalog. Part of the records are being transcribed from label images on the Symbiota-run Bryophyte Portal. Once the transcription phase is completed, these records will be imported to the institutional database. All records combined can be searched online here.

The Bryophyte Voucher Search option has been discontinued. Please email B. Shaw with requests for collection data of all specimens used for scientific research including the voucher details. Vouchers are labeled as culture, cytological, DNA, ecological, isozyme, morphological.

The list of Duke exsiccatae series is available here.

Questions about the online catalog or its use should be addressed to B. Shaw.

The author abbreviations of scientific names are used according to MOSs TROPICOS database.

The name of the person who made the determination, and names of collectors are presented in the format: Last name, First name, Middle initial.

Users have the option to download all Search Results in comma-delimited text file from the Bryophyte portal.

Specimen identifiers

DUKE bryophyte herbarium uses barcode as a unique identifier. Barcode refers to the barcode attached to the specimen. Specimens cataloged early in our databasing efforts at Duke do not have barcodes. Specimens of epiphyllous liverworts consisting of multiple taxa on the same substrate (leaf) contain multiple barcodes.

In the past, we've used Catalog number, a number assigned automatically during the cataloging in Specify 5 databasing system. It has been abandoned during migration to Specify 6 collection management software.

When requesting a particular specimen on loan it is helpful to cite the Barcode number.


Cannot find your taxon in the catalog?
Try other nomenclatural combinations of the taxon name. We welcome your feedback on errors in our data related to taxonomic and nomenclatural synonyms! Contact .

Using non-english alphabet?
Please try searching persons and localities both with and without accents in the names. Send us your feedback.

Are images of the plant or the specimen label available?
We've started to build a collection of bryophyte images. They are available as part of the bryophyte portal. Specimen label images are available for part of the North American moss collection, and most of the liverwort collection.

Am I searching your database directly?
The web search is querying a web cache; you are not searching the catalog directly. The web cache is being updated weekly.

Databasing bryophyte records in DUKE was supported by NSF grant award no. 0444586 to A.J. Shaw, NSF grant award no. 1115001 to F. Lutzoni & A.J. Shaw, and by the Duke University. This project would not have been successful without generous IT support of Susan Gerbeth Jones, Blaine Ott, and Specify software team.

Questions about the online catalog or its use should be addressed to B. Shaw.
