Towards the very end of his academic career, the Swedish naturalist Carl Linnaeus (1707–1778) – best known today for his “sexual” system of plant classification and his binomial nomenclature – used little paper slips of a standard size to process information on plants and animals that reached him on a daily basis... Both volumes had nearly 600 pages; the first Mantissa alone contained 25 new genera and – as Linnaeus explained himself – “more than 400 of the rarest species, which partly have never been referred to a particular genus, and partly are completely new. ” It is likely, then, that the title rather expressed the fact that Linnaeus had failed to integrate new information into further complete and updated editions of his taxonomic works, thus reducing the value of the book... As we will see in the next part of our paper, it was Mantissa plantarum altera for which Linnaeus first used his paper slips, and the quoted passage from the preface to this book is the only instance, as far as we can see, where Linnaeus makes explicit reference to this new working method... Linnaeus initially seems to have used the paper slips much like he had used loose sheets for his Species plantarum in the late 1740s, that is, as a preparatory manuscript... In the case of specimens sent by collectors, it is often possible to relate the respective slip to the letter sent by the correspondent and to a specimen that is still preserved in Linnaeus's herbarium... On the likely assumption that Linnaeus processed information contained in letters shortly after their receipt, it is possible to conclude that Linnaeus started the process of collecting information on paper slips just after the publication of the first Mantissa in 1767, and that he did not stop using paper slips after Mantissa plantarum altera was published in 1771... In this case, a pair of slips drawn up from different sources was used over a period of more than two years to systematically collate information and settle on taxonomic assignments (Figure 3)... It is highly likely, although impossible to demonstrate conclusively, that this went along with a re-shuffling of the paper slips... Linnaeus now had two herbarium specimens carrying the same name, and a letter to Bäck on 12 September 1773 mentions that he had “received so many of this genus [i.e. Ixia] that they need close examination. ” In the course of this examination, Linnaeus apparently reached the conclusion that the two specimens of Ixia crispa actually represented different species, since he changed the trivial name of Sparrman's specimen from Ixia crispa to Ixia undulata... They bear a striking resemblance to Linnaeus's later slips (Figure 7)... It is tempting to conclude that, while cataloguing the Queen's collection, the first seeds were planted for the later independent “invention” of paper slips by Solander and Linnaeus... In the stages of Linnaeus's working process, they occupied a sort of middle ground: while the first step was to draw up a list of specimens provisionally assigned to species, the paper slips allowed Linnaeus to note down their characteristics, to compare species with each other, and to allocate names to them.

Figure 0003: Schematic chronology of paper slips for Polypodium fragrans, in relation to specimens sent by Friar Gabriel (25 August 1767) and by Johan König (22 February 1769).

Mentions: Linnaeus probably amended both species and genus name more than a year later following the receipt of another specimen of the same species from Johann Gerhard König (1728–1785), a former pupil of Linnaeus and Danish physician who travelled to Tranquebar, Thailand, and Ceylon from 1773 to 1785.61 König sent a long letter from Tranquebar dated 22 February 1769, which was accompanied by some specimens. After drawing up a slip for the species Pteris fragrans, based on a short description sent by König along with a specimen, Linnaeus later crossed out Pteris and replaced it with Polypodium, but retained the specific epithet fragrans.62 Now, the slip drawn up for the specimen received from Friar Gabriel, and later amended to Polypodium fragrans, has a little note at the bottom reading “conf. Pteris fragrans,” while the slip based on König's specimen carries a note on its back reading “confer Adianthum pusillum.” Information from both paper slips was finally systematically drawn together in the description of Polypodium fragrans in Mantissa plantarum altera.63 In this case, a pair of slips drawn up from different sources was used over a period of more than two years to systematically collate information and settle on taxonomic assignments (Figure 3). It is highly likely, although impossible to demonstrate conclusively, that this went along with a re-shuffling of the paper slips. At least today, both slips are kept together with slips on three other Polypodium species.
