Botany Collections

The plant collections of the Smithsonian Institution began with the acquisition of specimens collected by the United States Exploring Expedition (1838-1842). These formed the foundation of a National Herbarium which today numbers over 5 million historical plant records, placing it among the world's largest and most important.

Over 4.2 million specimen records (including over 115,000 type specimens with images) are currently available in this online catalog.

Search the Botany Collections

Select a tab on this page to search by Keyword or Selected Fields. Searches are limited to 10000 records and the results are sorted by taxonomic group. If you need to retrieve a larger record set, contact the Department of Botany's Data Manager.

Disclaimer: The US Herbarium’s Collections records may contain specimen labels that include offensive or culturally insensitive language. These records do not reflect the US Herbarium’s current viewpoint but rather the social attitudes and circumstances of the time period when specimens were collected or cataloged.

Use the By Field search to find specimen data that match values in specific database fields. Enter a value or choose one from the dropdown lists.

  • Click the Search button to initiate a search. Clear resets all fields.
  • Some lists are linked, so for example, choosing a Country narrows the choices for Province/State/Territory, and District/County. Dropdown choices also narrow as you type, for example, typing zing in the Family field might narrow the choice to Zingiberaceae.
  • Check Only Records with Images if you want to restrict the search to records with multimedia content.
  • You can force an exact search by surrounding your search text in double-quotes. Exact means exact, the search is case-sensitive and must match the value of the entire field. An exact search will also take much longer to complete.
  • You will receive a warning when you enter invalid information in the text fields. For example, Catalog Numbers are composed strictly of letters and numbers; other characters raise a warning.

Search will be unavailable on Tuesday, 17 April, from 10 to 10:30 AM (EDT)

Enter your keywords separated by spaces and click Search. Records that match your search terms will be returned.

Note that searching for common (vernacular) names may not yield the expected results. Associating common names with specimen records is a work in progress.

The results of your searches can be displayed in Grid (a sortable, customizable table) or Gallery View (best for reviewing images). Use the Switch button Change View to cycle between these views.

In Sheet View:

In Grid View:

In Gallery View:

See Exporting Results for information on downloading results to, for example, Excel or Google Earth.

Open the full collection record by clicking the expansion button (Expansion button) in Grid View, on the scientific name in Sheet View, or anywhere within the image frame in Gallery View. Inverse expansion buttons (Collapse button) indicate records with multimedia (typically, images).

Sort results in Grid View by clicking the column header (or by choosing Sort from the column's dropdown menu).

Export all or selected results by clicking the Export Results as CSV button in the bottom toolbar in Grid , Sheet, or Gallery View.

You can also export all or selected results to a KML file for viewing with Google Earth or other KML viewers, by clicking the Export as KML button. This button is grayed when all or selected results lack latitude/longitude values.

Here are a few search tips:

To create a link to specific records at NMNH provide a querystring for:

https://collections.nmnh.si.edu/search/botany/?QUERYSTRING

where QUERYSTRING is (use a plus-sign to separate case-insensitive terms):

It is best to use only letters, numbers, pluses (+), dashes (-), and commas in your querystrings, and to avoid other characters.
