It's been a week of finding "different" plants..................

We took another "exploratory drive" today being Sunday........ We have so much to discover on 100 000 hectares of "bush" that is so alien to us....... Found another scrubby looking bush, I won't call it a tree, as doesn't seem to get too tall, covered in these fruits which just want to make you bite into them.  The birds had already been having a feast, so am sure its safe to munch on, but I had better wait for the ok!  The fruit reminds me so much of the "custard apple" Cherimoya Fruit  or the "ox heart"  Annon reticulate which we know..... What do you think......
