There is a much simpler was to look at this. Lets say there are two cars, same brand, same model, same colour. The number is different - easiest way. When number is same? oh, the seat colour is different. When seat colour is same? One seat is leather and one seat is false leather. When both seats are leather? .......
So basically saying, sometimes, it becomes harder to make out the differences. So we go for details on minor scale. both seats are same but one is shiny leather and other is suede. For example, we cant make out the difference easily between Tinospora cordifolia and T. sinensis, we say one has hairy petiole other has not. It may not work for all other species, like Spiranthes sinensis comes in both hairy and glabrous form. So we look for other options like dna, may be stomata, may be structure of these hairs. Sometimes it is helpful, sometimes it is not so we keep exploring more and more options.
