Apomixis in Orchids

for a bit of background to apomixis read this

I have a request - help!
I carried out an intergeneric cross and have just found out that there has been seed germination in the flask. By all accounts the cross should be impossible.
However I found out via another forum that the pod parent could be apomictic, but no further info could be obtained.
Can someone help with specific info ? The pod parent plant is a hybrid of Aganisia Cyanea ( formerly Acacallis ) and a Zygopetalum. Do you know if any of these are apomictic ? Do you have a source, or can post a link ?

Another interesting fact is that I subsequently backcrossed the pod parent to another ( different ) Zygopetalum and the pod was sterile !

I came across this article too and have e-mailed them for info...

Understanding Apomixis: Recent Advances and Remaining Conundrums

quote
"Apomicts are found more commonly in habitats that are frequently disturbed and/or either where the growing season is short, such as arctic and alpine sites, or where other barriers operate to inhibit the successful crossing of compatible individuals, such as among widely dispersed individuals within a tropical rain forest (Asker and Jerling, 1992)"

the highlighted part is salient because I have read that Aganisia sp. can spend a large part of their life cycle under water, during Amazon flooding.
