A list of plant, desired for a herbarium, bound and with thin paper as cover. On cover: '"Defecta Herbar.". Ms Linnaei' (later hand, possibly James Edward Smith's).
Spencer Savage, who identified the manuscript as being in Osbeck's handwriting, thought it referred to Linnaeus's herbarium, but Arvid H. Uggla countered that Osbeck seems to have had nothing to do with this, and then plants grown in the Uppsala botanical garden would not have been referred to. It is possibly a list for Osbeck's own herbarium, or for Count Tessin's (1695-1770) herbarium. Osbeck started working for Count Tessin from 1755, as superintendant of Tessin's natural history collections.
At the top left of folio 1: 'Till Hr Solander', referring to Daniel Solander (1733-1782) who was a student of Linnaeus between 1750 and 1759. The date must be between 1755 (reference to Linné, Carl von. 1755. "Centuria I. plantarum". Uppsala) and Daniel Solander's leaving Sweden in 1759.
Arranged according to the sexual system, use of binomial nomenclature.
Different marks designate Swedish plants, ones that are supposed to grow in the Hortus Upplandicus, and those of which the writer has specimens, but only bad ones.
Several notes provide commentary on exisiting specimens:
