defining a collection that accepts any implementation of generic class

I have a generic abstract class Plot<T>. How can I define a collection that will accept any implementation of the abstract class? I have tried the following approaches without success:

public List<Plot<object>> Plots = new List<Plot<object>>();

public List<Plot<dynamic>> Plots = new List<Plot<dynamic>>();

Thanks.

Situations like this usually call for creating a non-generic base class, from which the generic class derives:

public abstract class Plot
{
    // Put anything which doesn't need T here
}

public class Plot<T> : Plot
{
}

Then you can create a List<Plot>.
