Manuscript interleaved. No title page.
39 folios written on both sides in double columns, with names of plants then known and a mark against such as were in the herbarium. This mark was at first an underscore as in the "Species Plantarum" but from the sixth page onwards the mark consists of a dot placed before the figure in front of each name.
Some interleaves torn out.
The last 10 interleaves have been used by Linnaeus the Younger for entering diagnoses of plants.
