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
professor of mineralogy and chemistry at
Chemnitz, later professor of botany at
Vienna and director of the botanical
garden at Schönbrunn. Correspondent
of Linnaeus.
for the letter of 20 September 1767Letter L3634, which had arrived on that same day. He is glad for the seeds, the drawings and the plants.

Linnaeus is very eager to obtain seeds of Loasa which Jacquin has promised to send.

Linnaeus has had flowers of several species of Heracleum and has transferred them to his garden in the country estate [Hammarby] in order to be able to observe them better the next summer, if they survive the winter. He is not satisfied with what he could see this summer. However, he sees that Heracleum angustifolium is a separate species and that Heracleum austriacum is not the same as Heracleum sibiricum. Linnaeus gives a number of other botanical details, i.a. on Heracleum sibiricum polygala, Chrysophyllum Carolinense and Cleome. On Anastatica Linnaeus can only give a tentative citation of literature.

Linnaeus has seen from public news that the Cykas palm has flowered in the Royal Garden in Vienna [Jacquin refers to the Botanical Garden of the University of Vienna, founded in 1754]. Linnaeus wants Jacquin to send him a drawing of the flowers and a character of the species, since the picture found with Georg Eberhard RumpfRumpf, Georg Eberhard

The letter concludes with some more botanical notes, among them a short character of a strange species of grass which Jacquin had sent. Linnaeus has not seen anything similar, but he may have seen it published somewhere; that book is not available to Linnaeus at the moment.

Linnaeus praises Jacquin for his good drawings.
