There are three entrances in the data base that I believe are the same thing.
Aconitum bicolor,
Monkshood (Aconitum x cammurum 'Bicolor') and
(Aconitum x bicolor)
I didn't know who to ask about this so I thought I'd ask about it here.

Thanks Sue. I'll look into it.

Not so easy Sue, but it's done. A. bicolor was easy to delete after going to various DB. A. x bicolor is accepted by both The Catalog of Life/ITIS and The Plant List/Kew. Fine so far. A. x cammurum is accepted as well, ARS-GRIN, The Plant List/Kew. In looking up Aconitum x cammurum 'Bicolor' however it gets interesting. The RHS DB notes A. x bicolor as a synonym of A. x cammurum 'Bicolor' with a reference to The Garden 2005, which is earlier than the ITIS reference for acceptance, 2011.

What I've done is left one DB entry:
Aconitum X bicolor: accepted
Also Sold As: Aconitum x cammurum 'Bicolor'

Monkshood (Aconitum x bicolor)
