In fact it lists *all* its arguments as usual (the default being ".", as
always), except that those which are directories are not listed
recursively. It doesn't "give a list of directory names", unless that's
what the arguments happen to be.
There are no flags to ls which mean "ignore any arguments which belong
to this class of object".

If you want to filter out directories, use grep, as several people have
pointed out. That's the Unix Way (tm).

Said beginners need to learn that *directories are files* (and devices
are files, named pipes are files, etc.). This is an important concept
which should not be hidden.
