It is not dead, it is just senescence.

Oh, and I guess that it is really silly to think that the Cycas pollen could be of any use to the Macrozamia lady?

Has anyone tried this or are they too far apart on the tree?

You are correct on the first cone being male on the Cycas.  Cycas is the one genus of cycads that does not form real female cones, forming "megasporophyll" instead (see picture below).  So if you ever get a Cycas with a cone, you will know it's male, and when you see structures like the ones below, they are female.

I'm not good at id'ing the Macrozamia cones, as I just have a couple of them growing. 

Final question about pollinating across genus, unless one believes in miracles, centaurs and mermaids then I wouldn't take the time to try.

Thanks Tracy, I didn't know that about Cycas, and you are funny. :)  I really wish that there were mermaids.

Cheers Steve
