On the left is a T. albertiana from Japie. Without a doubt one of the most vivid petal colors of the genus. On the right is one of Mark Dimmitt's creations; 'Mystic Rainbow', which is albertiana x arequitae. FCBS has a small section of Mark's 'Mystic' crosses which I suggest you check out for some amazing colors. I'll post other 'Mystics' when they bloom.
