Probably the most commonly planted Magnolia in Indiana is Magnolia x soulageana. A few weeks ago I noticed that not only were there no reports on iNaturalist for Magnolia x soulageana in Indiana but none in the rest of the USA either. Yesterday I found a report of Magnolia not identified to species. It being Magnolia x soulageana, I put the species name on the report.
Saucer Magnolia (Hybrid Magnolia × soulangeana) from Earlham College, Richmond, IN, US on April 13, 2021 at 06:21 PM by bksniegowski · iNaturalist
Now this report has disappeared from the Magnolia section for Indiana which is where I found it in the first place. Why can’t I find any reports for Magnolia x soulangeana in the USA?
Observations · iNaturalist
This is a cultivated species and should be marked as cultivated for that reason. For some species in a given area if the proportion of “casual” (cultivated) observations of a species exceeds wild occurrences it will automatically trigger the site to mark it as cultivated.
Also, cultivated species are fine to upload but they’re not as important as observations of wild species. I am speaking for myself here, but sticking to wild species for the majority of your observations would be the most useful.
There are over 6000 (verifiable and unverifiable) observations in the US: https://www.inaturalist.org/observations?locale=en&place_id=1&preferred_place_id=1&taxon_id=204586&verifiable=any
You may see what you see if you limit the search to the section https://www.inaturalist.org/taxa/1330821-Magnolia – the hybrid is not grafted to that section, it is grafted to the genus. If you think it should be grafted to the section, please flag the hybrid on iNaturalist directly.
In your last link, uncheck the “Verifiable” box in the filters to show Casual observations (where captive/cultivated observations are classified).
welcome to the forum :)
(I’ve moved this to general since it’s not a curation issue)
In addition to the above, Magnolia x soulangeana is a sterile hybrid, so it’s unlikely that any observation could be verifiable since it cannot self-seed.
