Chris.
Good color on your bloom. Looks like your temps are into the lower to mid 60's, but still with good light. The lower fall temps give the mid ribs their darker color & at the same time the bright light gives the petals a light blush. I would guess that it's a semi-alba cross, or semi-alba by a light blush.
Your plant's also blooming in early fall rather than late fall into winter. Your day length must have shortened quite a bit since summer to trigger the bloom.
Yes, the plant came from a good friend in Florida where it got very warm winters with little day to night difference. It always bloomed semi alba before this.
The cross is 'Puanani' x 'Tokyo #1" SM/JOGA
My temps are at least a 20 degree difference every day, through most of the summer it can be as high as nearly thirty, with nights in the high 60s.
