Wow, thanks a lot, Lorn. That must have taken a lot of digging, and we all appreciate it!
I've never heard of L. davidii var. Maxwill. In fact I had just assumed you meant willmottiae, until you used willmottiae in the same paragraph. Goolgling finds that it was used synonymously with willmottiae, but there is also a cultivar:
'Maxwill' (Skinner, 1932) - to 220cm, with 30 flowers or more. Flower is orange-red with a few dots.
I also assume virus "resistance", is virus tolerance.
