[Taxacom] Ambrosia Herbarium Samples

[Péter Poczai]

Dear Taxacomers,

I'm looking for herbarium specimens from the following species of Ambrosia.
They seem to be rare and I can't find them anywhere. Does anybody know
existing specimens where I could obtain leaf segments for DNA analysis?

*Here is the list:*

1. Ambrosia cordifolia (A.Gray) W.W.Payne
2. Ambrosia diversifolia (Piper) Rydb. (Syn: Ambrosia artemisiifolia ssp.
diversifolia)
3. Ambrosia johnstoniorum Henrickson 4. Ambrosia tacorensis Meyen 5.
Ambrosia tarapacana Phil.
6. Ambrosia villosissima Forssk.

Best,
Péter
