Select all elements that have a specific CSS, using jQuery

How can I select all elements that have a specific CSS property applied, using jQuery? For example:

.Title
{
    color:red;
    rounded:true;
}

.Caption
{
    color:black;
    rounded:true;
}

How to select by property named "rounded"?

CSS class name is very flexible.

$(".Title").corner();
$(".Caption").corner();

How to replace this two operation to one operation. Maybe something like this:

$(".*->rounded").corner();

Is there any better way to do this?
