Frequently (and not so frequently) Asked Questions
BRIEF: Need macro and microscopic identification of Atropa belladonna.
We are attempting to access some information about Atropa belladonna in regards to developing both macro- and microscopic identification. Atropa is known as a sometimes-adulterant of Arcticum lappo (burdock), and we need to develop a means of identification for this species.
UC Berkeley has an exhaustive photo collection of plants on line, but I am not sure it includes seeds. I think your best bet is to go directly to your nearest large herbarium (UCLA or UC Riverside; I am not sure CSU, Long Beach has a big one), make friends with the curator and spend some quality time with dried specimens of Atropa and its seeds.
