The "+" (Or -, ~, #) are the visibility marker. "+" means "Public".
No icon means "Undefined visibility". But it is not clear in the UML Specification what this means exactly. So, for "Public" elements, you can have either no overlay (The visibility has never been set), or the green "+" overlay (The visibility has explicitly been set to public)
