This is a gateway to data and images of all taxa of herbarium specimens held at The University and Jepson Herbaria, University of California, Berkeley. For type specimen lists and images, see Type Specimens at UC/JEPS.
For more California vascular plant records, visit The Consortium of California Herbaria for specimen data from 30 contributing institutions.
A collector search for Joseph Rock will return both algae and vascular plants. Clicking on the full tab will let you see the complete collections data with thumbnails, maps etc. Searches can be restricted to major taxa by selecting them by major group.
Dates can be searched and multiple images per specimen will be returned if there is additional data in the packet, on the back of a specimen sheets etc. This includes living plant photographs when collected in conjunction with specimens.
Searching for specimens by scientific name Cupressus to* will return all Cupressus specimens with specific epithet starting with “to”.
Specimens that are georeferenced can be mapped individually by the clicking the map link in the specimen record or the maps tab at the top of the search by locality such as Godalming.
The facets tab can be used to rapidly narrow search results to taxon, individual collector, counties and states.
Wildcard symbols (* and ?) may be used in keyword searches to match any character(s) within a search term. '*' denotes zero or more characters at a given place within a search term. Each '?' denotes zero or one character; it may be used more than once in a row to match a desired number of characters. Remember to set the search type option to "Keyword".
Boolean Logic Within a Field
The portal includes type specimens and images when present and searches can be restricted to major taxa. Default search returns are in a grid view but clicking on the full search view allows all captured fields to be viewed (phenology, label headers, depth etc.).
You can enter search criteria by typing into the text boxes or selecting an option from a pick list. You may also click one of the "Display options" to choose the format of your results ("List" is the default) or to limit the number and type of results you wish to receive. Any combination of fields may be used.
Some fields have an option of searching as either "keyword", "phrase", or "exact".
Wildcard symbols (* and ?) may be used in keyword searches to match any character(s) within a search term. '*' denotes zero or more characters at a given place within a search term. Each '?' denotes zero or one character; it may be used more than once in a row to match a deisred number of characters. Remember to set the search type option to "Keyword".
You may also search for records where the value for the field is empty by entering Null in the field.
Run the search by clicking one of the display formats or pressing the return key when any field is highlighted.
Displaying Search Results
If your search has one or more results, you'll see three panes presented -- Results, Facets, and Maps.
There are three options for display.
After performing a search, clicking the "Facets" tab will show you a list, in descending frequency order, of values which appear the records returned by your search. For example, if you search for collector W. L. Jepson (exact), you will see under County San Bernardino 1650, Solano 1385 etc., meaning there are 1650 Jepson specimens collected in San Bernardino Co., 1385 specimens from Solano Co. etc. Clicking on the name of a facet will refine your search, returning only the results matching that value.
For most fields, the sum of the facet counts will equal the total number of records. The exception is the collector field. Since there can be multiple collectors for a single specimen, the collector counts can exceed the total number of records. For example, search for collector Setchell and view the facets tab.
You may choose two different mapping options for your result set:
Berkeley Mapper: your results will be passed to Berkeley Mapper and plotted there.
Google Static Maps: up to 65 of your results will be plotted on the spot using Google Maps.
