List produced on RBGE embossed paper, bound together to form a book; beginning with Ranunculaceae, there are 330 pages of plants growing in the Garden in 1883 (though the 3 could also be interpreted as a 5); the book has an index at the back.

2 volumes of unpublished manuscript produced by Janet Rae in the early 1980s. George MacDougall may have typed the manuscripts. The idea was to produce something similar to a book already published, but it was considered too expensive and that there was not enough demand to publish this one. The manuscript does include illustrations, including at least one original pen and ink sketch by Alan McGillveray, and constitutes a description of Edinburgh's changing landscapes in c.1983.
The accession also includes 2x 2020 calendars marking the Society's 150th anniversary in 2019.
