Share up to three original photos of the same subject or event. Each file enters private review. We check identity, provenance, permission, credit and privacy before any public use. Permission to submit for review does not grant public-display or third-party reuse rights. Read our rights and attribution policy. Review notice photo-review-v1.2-2026-09-27.

ⓘ What should I write here?

The rights holder is the person or organization that owns the copyright in the image. This is often the photographer, and may differ from the owner of the plant.

• Your own photo: “I took this photo and own its copyright. Rights holder: [your name].”
• Someone else’s photo: Name the rights holder and describe the permission they gave you, including any limits. Include a link or reference to that permission if available.
• A licensed image: Name the rights holder and give the license name or version and a link to its terms and the image source.
• A public domain image: Give the source and explain the documented reason it is in the public domain. Finding an image online does not by itself make it public domain.

If you are unsure, describe what you know so we can review it. Submitting for private review does not automatically authorize public display or reuse.

Submit photos for review

Historical records and plant provenance

Old nursery catalogs, dated plant or flower photographs, original labels, accession records, and a known chain of ownership can help clarify Hoya names and history. Include the name as recorded, any dates, where the material came from, and what you know about the plant’s history. Use “Tell us about a source or lead” above for historical material, or “Contribute photos” for your photographs. Approximate locations are enough; omit private addresses and sensitive wild locations. Submissions enter private review.

What happens next

Research information and photos enter private review. A lead or a claim can be submitted without a complete citation; we keep uncertainty visible and verify it before changing a research page. Each photo receives its own identity, provenance, rights, credit, and privacy review. Receiving a submission does not mean accepting, incorporating, or publishing it.

Ordinary questions and suggestions go to a separate private contact inbox. They do not automatically become permanent research evidence.
