Corrections
If a figure on a stem profile does not match what you see on your own bench, say which species, which cultivar if you know it, the room temperature and the water you used. Specific reports get checked against the original bench notes and the profile is amended with the date changed.
Press and permissions
You may quote up to 200 words from any profile with a link back to the page. For anything longer, for translation, or for reuse of the generated diagrams, write first — permission is normally given, but we like to know where the material is going.
Security and privacy requests
Requests relating to personal data — access, correction, deletion, or an objection to processing — go to the same address and are handled under the privacy policy. Please put the words privacy request in the subject line so it is routed correctly.
