Bc. Algernon 'White Christmas' (bottom left) and others, January, 1965. The slide is not labeled, but the photo was clearly taken about the same time as several photos of Kay in her greenhouse. The label is tipped on its side, but appears to be Bc. Algernon 'White Christmas'. There is another photo of a different cultivar among Kay's slides, 'White Spendor', the red lines in the throat hardly visible at all.
