James,
(And I suspect you are going to hate the answer !!!) - but the T. ordinoides, (as well as the T. s. pickeringi), came from "Bob" !!!!
I am sitting here (with a can of Foster's in hand), so if you PM me your number I will give you a voice call - also please note I am up in the Cheshire area just about every weekend, and it might be good to meet face to face.
Cheers,
Brian.
