How to remove orphaned features

Question

I found some orphaned features under "_layouts/ManageFeatures.aspx?Scope=Site" but they do not show up when I list them up with powershell (get-spgetfeature -site url). They are not in 14 hive and cannot be found through the "SharePoint Manager".

What can I do to remove these features?
