Hi
I have just ordered The Stanhopea Book (2010) written and ordered through Dr Rudolf Jenny. It's quite expensive but truly worth it from all the reviews I've read. Dr Jenny has written a lot about Stanhopeas and was credited for his support to Barney Greer when he wrote The Astonishing Stanhopea's.
Details here....
AOS | The Stanhopea Book
Have recently bought a considerable collection of Stanhopeas, although the original owner is still looking after most of them due to current living arrangements.
Here are a mixture of Stanhopeas that have flowered over the years....
Good luck...
Cheers
John
