Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

March 14, 1923. "Mary Wallace." Daughter of Agriculture Secretary Henry Wallace. National Photo Company Collection glass negative. View full size.
Mary's older brother Henry A. Wallace followed in their father's footsteps and served as Secretary of Agriculture during FDR's first two terms and as Vice President during the third term. He would have become President upon FDR's death, had Truman not replaced him as VP.
Pretty sure those aren't daylilies but are a species of the nearly 100 in genus Hippeastrum. These are the flowering bulbs, prized for their ability to be forced indoors during winter, that are commonly referred to as "amaryllis."
Genus is homo, species is sapiens, variety is female.
This is just a wild guess, I am not a horticulturist (or a Presbyterian) but I believe the genus is hemerocallis giant (daylily) with blooms up to 10" across. Am I even close?
P.S. After reading the comment titled "Hippeastrum a/k/a Amaryllis", I have to agree with that conclusion. I see them often around Christmas in bright red and other colors and they have fuller, more abundant petals than lilies and if you look them up, you can see that Amaryllis is what they actually are. I'd like to change my vote please.
C'mon, flower people; show all the car, train, airplane and call-box identifiers what you're made of. Genus, species and variety, please.
