I did a little research. On the "acronym list" of our seedlist is MH Manfred Hils. And on our seedlist is a lindsayi cobrensis MH15 which came from Areponapuchi. No mention of MH 09, but it must be nearby MH 15. You have to wait for an answer till Plein is back from the Afm meeting in Klagenfurt next monday or tuesday. He will know, because I believe that Manfred Hils was travelling together with Plein and Rogozinski.
And I've never heard of M. Haberkorn too, Chris.
