Forum Flora Germanica

Dear Colleagues,

My name is Csaba Molnár, and I am a botanist from Hungary. I am primarily involved in floristics. Among other things, I am conducting taxonomic research on Potentilla, specifically on the taxa of the highly complex Potentilla incana - verna - heptaphylla group found in our country. I would like to gain a better understanding of the taxa that live in our country, which is why it is essential to examine the original type specimens. I would like to ask for your help. There are three important taxa about which I know nothing regarding their type specimens:
Potenilla adulterina Domin 1935
Potentilla puberula Krašan 1867
Potentilla arenaria Borkh. 1796
Does anyone know which collection these are kept in? It would be even more helpful if a photo or scanned version of the type specimen were available.

I got your contact details from my colleague, Tamás Exner.

All the best!
Csaba

Dear Csaba,

thanks for asking. The expert for Potentilla here in Germany is Thomas Gregor, who has published (among others) a list of the names of the Potentilla collina complex here http://www.flora-deutschlands.de/collina_namen.pdf.
Unfortunately, your 3 species are not in this list.

I will send you his contact details by mail.

Dear Michael,

Thank you very much! I will look for Thomas Gregor. The table you sent is very valuable, but it covers a different Potentilla group. Therefore, I still hope that someone might be able to tell me where these three type specimens can be found.

Alll the best!
Csaba
