Linnaeus thanks Nicolaus Joseph von JacquinJacquin, Nicolaus Joseph, baron von
(1727-1817). Dutch. Botanist. In
1755 at the order of emperor Franz I of
Austria he went to the Antilles and
South America. In 1763 he became

Chemnitz, later professor of botany at
Vienna and director of the botanical
garden at Schönbrunn. Correspondent
of Linnaeus. for two letters [20 October 1760Letter L3976] and [27 September 1760Letter L2786] and starts to answer the detailed questions in them.
Among these notes, Linnaeus remarks that the herbarium from the island Eustatius contains at least 350 species. The birds described by Jacquin will be introduced into the Systema naturae under Jacquin’s name [Linnaeus means a forthcoming edition; the next published edition was Systema naturae, 12th editionLinnaeus, Carl Systema
naturae, 12th edition (Stockholm
1766-1768). Soulsby no. 62. ]. The seeds of Cherleria were not good, so Linnaeus asks for details instead.
Linnaeus had received a copy of Jacquin’s work [Linnaeus refers to Enumeratio systematica plantarumJacquin, Nicolaus Joseph, baron von
plantarum, quas in insulis Caribaeis
vicinaque Americes continente detexit
novas, aut jam cognitas emendavit
(Leiden 1760). ] on the previous day, through Johan Frederik GronoviusGronovius, Johan Frederik
(1690-1762). Dutch. Naturalist, senator
of Leiden. Linnaeus’s benefactor and
friend. Published Flora Virginica
(1743, 1762) together with John Clayton.
Correspondent of Linnaeus. , and he had been unable to sleep in the night after having studied it until late. He praises Jacquin’s descriptions and diagnoses of the new species but has to ask for details, especially on the sexual parts. On Terebinthus, this question goes into great detail, since three variants have the same name. But Linnaeus is very grateful that Jacquin has adopted his method, and he says that Jacquin writes like a sixty-year-old botanist. Jacquin has discovered more new plants than anybody else.
Linnaeus would have wanted to write more but has no time since he has to go to Falun for a fortnight. He encloses some seeds that he happened to have available.
