Potentilla sp. and Fragaria sp.

[Ugur Bal]

Dear Memebers of the Group,

I wish everyone a happy new year and a succesful term.

I actually send this post earlier and did not get any answer which was 
probably because everybody was on holiday. So I would like to renew my 
question as to whereabouts of some Potentilla sp and Fragaria sp..

Since most of the following species are found only in private 
collections I need some help to find out the seeds of the following 
species which will be used in my experiments:

Potentilla fruticosa (2n=4x=28; has got to be a tetraploid)
Potentilla reptans
Potentilla anserina
Potentilla erecta
Potentilla rupestris
Potentilla glandulosa
Potentilla nepalensis

Duchesnea indica

Fragaria vesca rosea (2n=2x=14; pink petalled)
Fragaria americana alba (2n=2x=14)
Fargaria chiloensis
Fragaria wirginiana
Fragaria moschata
 
P.S. I am desperate for the tetraploid Potentilla fruticosa

Thank you very much
