3a

Photographic negatives are organized in 6 independent sequences (3a to 3f), based on size and media. Three material sizes are (3a, 3b) 6.25 x 8.25; (3c, 3d) 4 x 6; and (3e, 3f) 3 x 5. Each size is organized in two sequences, glass or acetate.

Negatives are numbered by year and/or hybridization number and are cross-referenced with corresponding positives. Most material documents species and hybrid studies (indoor and outdoor), life cycle studies, staged displays, garden views, landscapes, and plant structure studies, e.g. seeds, capsules, foliage, scapes, and flowers. There are photomicrographs of plant cell structure, comparative studies of Hemerocallis clones, herbarium specimens of the Kew Botanic Garden, imported packages of dried daylilies for use as a food vegetable, and portraits of Dr. Stout at work, including views of the NYBG experimental garden.
