I would be very interested to receive a dried sample of this which is in good condition as it is one of the species we really want to sequence. If you are interested to collaborate with us let me know. I think you could get my email off Christian. I will also check the literature and we may have already looked at the type. Thanks Kevin
I will ask your email off Christian.
