I recently posted a question regarding a strange fruit that I found, and have now by chance positively identified it, and would like to thank those who responded to my query.
It is in fact the fruit of a twining climber originating from China/Japan, and that climber is Akebia Quinata, a good alternative to Russian Vine for hiding the unsightly.
Thanks to all,
David Wheatley.

A belated thank you (due to computer incompetence!)
to all who responded to my recent query regarding the fruit I found in the garden, and now identified as Akebia.

Ah, Akebia Quinata. That makes sense now as I had thought that you had halved the fruit and Akebia Quinata fruit naturally opens like that! I am growing ones from seed this year round a yew (It sounded a good idea to me at the time). They germinated within a few weeks in the greenhouse this summer.
