I'd suggest learning the proper name from the start.
Forget all the virgin's bowers and batchelor's buttons.
Learn about plant families, you can get a short-list of possible IDs if you recognise family features.
Agree with Dave re finding out about the plant, it's important knowledge, ID is just a start.
Don't try and learn too many at once unless you have a very good memory.
