Nicolaus Joseph von Jacquin sends some plates and makes comments, among which are the following:
Gnaphalium Leontopodium had been very carefully examined by Jacquin, who had found all flowers quite alike. It seems that Antonio Scopoli had some other information on this plant, especially on different types of flowers. Jacquin also comments on the layout and arrangement of the plate.
The Silene is a new species, Silene alpestris.
A Hieracium, not published, is very common in the Alps. Jacquin describes it in outline and has an alternative attribution.
The deceased C. Rijk Tulbagh’s gardener had by chance visited Vienna on his way to relatives in Hungary and brought bulbs from the Cape of Good Hope. Jacquin had bought them and started to plant them, and they are beginning to germinate. The gardener did not know any names. Jacquin sends a small specimen to Linnaeus of a plant that behaved strangely. He asks if Linnaeus can help him with the attribution, name etc., if Linnaeus had seen it before.
Jacquin wonders if the tea bush is still alive in Uppsala.
Jacquin asks for information on the botanists José Celestino Mútis and Frédéric Allamand whom Linnaeus mentions in Mantissa plantarum altera, 2nd edition.
Jacquin asks Linnaeus not to forget to ask the Queen, Lovisa Ulrika if she wants to acquire one of the special copies of the work on the Vienna botanical garden ((Jacquin refers to the Botanical Garden of the University of Vienna, founded in 1754, and Hortus botanicus Vindobonensis).
Jacquin encloses specimens of Artemisia and Justicia, which Jacquin thinks are new species. He can send seeds of Justicia, which grows in a warm room.
