Newbie - Rejected photos - Intellectual Property - Non-conform

I submitted four photos to Adobe Stock. Three were rejected.

Two for 'non-conform' images, one for 'intellectual property'.

All three are pictures of dried plants...

There are links to explain the root cause, but these links point to general text, that does not clarify things.

While I can understand that a photo is not conform (e.g. technical reasons), I do not see how anyone could have intellectual rights on a plant.....

Anyone an idea what has gone wrong?

Thanks

Alan
