It is likely that most of the photographs of plants in this series were taken at either the Arnold Arboretum in Jamaica Plain, Massachusetts or at the Harvard Botanical Garden in Cambridge, Massachusetts. Indeed, several images (108, 112, 113, 118, and 119) can be verified as being taken at the Harvard garden. It is also possible that this was a student project undertaken by Sears when he was studying at Harvard. Many of the images include corresponding note cards listing the scientific names of the plants, as well as the date of the photograph(s). Some images originally housed in this series that appear to be of locations other than the two cited above or that have a different documentary intent have been removed to other series (including SRS008 and SRS015).
The folder includes worksheets, notecards with plant names and photograph dates, photocopies of box labels, and other information.
