It's only a tiny plant at the moment. If you wait a few more years to let it grow to a more recognizable size before you totally decide what you actually have will make things a lot easier to distinguish what you actually have.
If this be the case then there are 100's of books and websites and plants in collections that require the same rules.
I only say this, as I have seen the difference of some plants over a couple years that haven't grown the way they were expected to. Theres short flower spikes and theres long, theres colours to think about and also size of actual plant to be able to tell what it actually is.
