A blank is not zero
A blank result, quantity or location means that no value is shown. It may not have been recorded, supplied or made available. Do not replace blanks with zero when comparing records.
Search, interpret and cite
Step-by-step help for using the search cards, choosing a data grid, filtering records, viewing details and downloading data. There are also tips for fixing common problems.
Quick start
The website, data grids and column layouts are still under development. The database currently requires a login and contains test/sample data. Use it to try the tools; the records are not final and should not be cited as research data. Example screenshots show the current interface, which may change.
Keep the illustrated manual for offline reading or printing.

Step-by-step help
Select a heading below to open or close its instructions. On a computer, pause the pointer over a toolbar button to read its label. Match the small icons beside tool names in these instructions to the buttons in your grid toolbar. The text labels also identify each tool.
Read the SeedPOD Terms of Use before using the database. After opening the grid, check the filter summary and clear any earlier conditions if you want to start again.
On Explore the Data, choose the circle beside the search heading you want:
Enter a name or choose a family before searching. The name box does not currently offer autocomplete: type your text directly, then select Search. For advanced expressions, use the column filters described in topic 6a.
Clear empties the selected card. Choosing a different search card also clears the previous entries; the other cards stay disabled. These actions change the form on Explore the Data. To remove filters from results already displayed in a grid, use the grid's clear-filter controls (topic 7).
rub in the name box and leave Family
set to All families.rub in the
CalcFullName column filter.
The screenshot shows 6,697 of 434,249 species records for that example. These are sample-data totals from the screenshot, not fixed counts. Search Term: none does not mean your card search was ignored: the name and family conditions appear under Grid Filters.
The status text calcfullname LIKE '%rub%' describes the contains filter. You do not need
to type that expression. To narrow the results further, add a compatible column filter; to broaden
them, remove an existing condition.
Open the table dropdown above the results. Its label shows the current grid, such as Species. Choose another table to explore it while keeping the species-name and family filters from your search.
Changing tables here keeps your search filters; choosing another search card on Explore the Data clears your form entries. The tables contain different kinds of records, so their columns and totals differ. Wait for the new table to finish updating, then check Grid Filters and the count. A filter can remain active even when its column is not currently visible.
The example now shows 354 of 18,294 test records. This is a count of tests, not a count of species. Switching tables does not mean that every record belongs to the one row you had selected: use collection or accession identifiers when following a particular seed lot.
In Collection Events, a collector's number helps distinguish one collection from another. In Seed Accessions, keep the accession identifier alongside the plant name and country. In Seed Tests, several rows can refer to the same accession because it has been tested more than once. Compare the test identifiers and dates rather than treating these rows as duplicates.
Each row is a record in the selected grid. Each column is a field, such as a family name, identifier or date. The boxes immediately below the column headings are filters.
A larger screen makes wide grids easier to use. On a small screen, show fewer columns and scroll within the grid rather than reducing the text until it is difficult to read.
Start with a small set: an identifier, plant name and the fields relevant to your question. Add more as needed. Hiding a column does not delete its data, and it should not be used as a way to clear a filter. Check Grid Filters separately.
For example, to look for species in Juniperus, start with Juniperus in the GenusName filter. This is an example to try, not a guarantee that every species in that genus is represented.
If you find nothing, check spelling, clear other filters and try the genus alone. A plant may be listed under a synonym or an earlier identification. The current sample data do not represent complete coverage.
Use a date or numeric field when you want to compare dates or quantities. Do not assume a blank value means zero. If a filter removes everything, clear the most recent condition first and check that the value belongs in that field.
For a value already visible in the grid, select its cell and use Filter on selected value. Check the resulting filter before adding another condition.
Write down the grid, fields and conditions if you need to repeat the search later.
Select the filter box below the relevant column heading, type an expression and press Enter. Wait for the results to update, then check Grid Filters below the grid to see the condition that was applied. Clear the previous filter before trying a different example.
Each example applies to the column you type it into. For plant-name examples, use a text column such as GenusName or CalcFullName. For number comparisons, use a numeric column such as NumberSown in Seed Tests.
| Type this | To find |
|---|---|
jun |
Text containing “jun”. Try it in GenusName and inspect the returned names. |
Juni* |
Text beginning with “Juni”, such as Juniperus. The asterisk stands for the remaining characters. |
*rus |
Text ending in “rus”. The SeedPOD example below uses CalcFullName. |
=Juniperus |
An exact match for Juniperus. Use GenusName, because a full species name contains additional text. |
<>Juniperus |
Values other than the matching Juniperus value in the chosen column. |
NOT Juniperus |
An exclusion using NOT rather than <>. Check the applied condition below the grid. |
>20 |
Numbers greater than 20. |
<20 |
Numbers less than 20. |
>=20 |
Numbers greater than or equal to 20. |
<=20 |
Numbers less than or equal to 20. |
<>NULL |
Records with a value in that column, excluding missing values. A recorded zero is different from a missing value. |
Check the whole field: an ends-with search in CalcFullName checks the end of the displayed full name. An author name or other text after the species epithet can affect the match. Use SpeciesName if your question concerns only the epithet.
*rus in CalcFullName. Example from 29
September 2026; the layout and results may change. View full screenshot (opens in a new tab).In this example, the status line shows calcfullname LIKE '%rus'. This is the database's
description of the filter; you do not need to type that expression. The screenshot shows 117 matches
out of 434,249 records at that time, rather than 117 records in the entire database.
To combine terms in one filter box, put AND or OR between them, in uppercase, with a space on each side.
Pinus AND nigra in CalcFullName to look
for values containing both terms.Juniperus OR Pinus in GenusName to
look for either genus.Press Enter and inspect the resulting rows and Grid Filters description. These examples act within the selected column. They do not search every field in a record.
Across columns: adding a filter in a second column narrows the existing results further. For example, a family filter and a genus filter must describe compatible records. Remember to clear the first condition if you intend to start a different search.
Try one condition first, then add another. If you get no results, check the spelling, field choice and other active filters before concluding that the data are absent.
Different controls clear different parts of your search:
To start again, clear any active search term and grid filters, then check the labels below the grid. Changing a plant name in one box will not necessarily remove conditions in other columns.
Select a sortable column heading to order the records by that field. Check the sort arrow and Grid Sort Order to see which ordering is applied. Use Clear applied grid sort order to remove it.
To explore the values in a field, select a cell in that column and use View a column summary. Read the displayed field name and any active filters before interpreting the summary.
Counts refer to records in the selected context. A count of test or accession records is not automatically a count of species, individual seeds or available lots.
Keep the record identifier as well as the plant name when contacting us about a result. Several records can share the same name. When comparing grids, use the relevant collection or accession identifiers where provided; similar names alone do not establish that two rows refer to the same material.
A heading or cell ending in an ellipsis (…) is shortened to fit the column. Use Column Manager to identify the field, and the record-details view to read the available value. Short numeric dates can be ambiguous: check the date format before interpreting a value such as 5/2/2008.
Select a record, then use View record images to inspect any linked images. A message saying that no images are available refers to that record; it does not mean that the search has failed. Check image credits and permissions before reusing an image.
Display map data opens a map beside the grid. In the Seed Accessions example below, 499 records are available and 129 are mappable and mapped; not every record has usable coordinates.
A record without a displayed location is not evidence that the species is absent from an area. Coordinates may be missing or withheld, and the dataset may not cover that area. Check location accuracy before using a mapped point for planning.
Select the species or accession row you want to investigate. The toolbar may then offer links to services such as Plants of the World Online, IPNI, GBIF and Genesys. Pause over a button to read its label and check whether it uses a name or an identifier.
These links are not available for every species or record. Availability depends on the selected record, the table and the names or identifiers supplied. A greyed-out icon may remain unavailable after selecting a row; it does not mean that your search failed.
Check the name and record returned by the other service. A name search can return several matches, and an external record may describe a different collection. Each service has its own coverage and terms of use.
Do not assume that highlighting one row means only that row will be exported. Check the options shown and the downloaded file. Keep identifiers, provider attribution and accompanying notes with the data.
For larger datasets or permission to use data outside the Terms of Use, contact seedpod@kew.org. Do not split a larger request into repeated downloads to bypass the limit.
The current records are test/sample data and should not be cited as research data.
When working with released data, keep the provider's attribution, record identifiers, access date and any supplied citation or use conditions. Record the grid and filters used so that you can explain how you selected the records. Follow the Terms of Use when using or sharing data.
Downloading a record does not request or reserve seed. Read Native Seed Supply for guidance on contacting the custodian and preparing a material request. Confirm availability, provenance, suitability and transfer conditions directly with the organisation holding the material.
Use Tab and Shift + Tab to move between page controls. Use the skip link to reach the main content. On these guide headings, press Enter or Space to open or close an accordion.
On the search cards, Tab to the search-type choices and use the arrow keys to select a card. Tab through its name field, family dropdown and buttons. Enter in the name field submits the active search. Selecting a different card clears the previous entries.
Within the grid, arrow keys can move between cells. At a filter cell, Enter can move into its input and Escape can return to the cell. Keyboard behaviour varies between grid controls, and some controls still have accessibility limitations.
If a control cannot be reached, understood or operated, contact seedpod@kew.org with the page and task you were trying to complete. See the Accessibility statement for known limitations and help obtaining information.
A refresh may help with a page that has stopped responding or is showing an older version. It will not fix every problem, including errors on the server.
Email seedpod@kew.org with the page address, approximate time, browser and device, selected grid, and the steps that caused the problem. Include the error message or a screenshot if possible. Do not include your password or confidential information.
Reading the results
A blank result, quantity or location means that no value is shown. It may not have been recorded, supplied or made available. Do not replace blanks with zero when comparing records.
Read germination or viability results alongside the test date, method, conditions, sample size and seed-lot history. Results from different methods or dates may not be directly comparable.
Several collections, accessions or tests can refer to the same species. Keep record identifiers when comparing them. Check synonyms and the original identification before treating similar names as different species.
Seed availability can change. A record does not confirm that material is available, suitable for your project or permitted for transfer. Confirm these points with the organisation holding the seed.
