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.
thanks Linnaeus for a letter of 2 September 1760Letter L2796, which he reads eagerly and answers before taking up other matters. Jacquin promises to send seeds of Cherleria, which covers the whole of Schneeberg. He wonders how Linnaeus’’s Juncus triflorus could be his Juncus uniflorus since he always saw it with one flower per stem. Giovanni Antonio ScopoliScopoli, Giovanni Antonio

had distinguished the two as different species. – Also other details are covered. The twig Linnaeus had sent was from Rhamnus Domingensis. The other species Linnaeus asked about should be Melia Guara, but as fruits are still missing, the determination has to stay open. On Petiveria, he reports that Linnaeus has made him so uncertain that he deleted his report from a publication under work (Jacquin refers presumably to Selectarum stirpium Americanarum historiaJacquin, Nicolaus Joseph, baron von

could have made a mistake and is glad that Linnaeus has got flowers on his specimen.

Linnaeus had said that he had got a herbarium from the island Eustatius. Jacquin comments that it should have been a very meagre one, if there were not also plants from the adjoining islands of St Christopher and St Martin.

The author of the work on military disease is Gerhard van SwietenSwieten, Gerhard van

Jacquin has trouble with a louse, Cimex oleraceus, that threatened to damage the plants he was growing from the seeds sent by Linnaeus. – He again promised to send seeds to Linnaeus; most of those asked for were already collected, so he would send them all when he had them. But he also asks Linnaeus for an early delivery of seeds to Vienna, to take advantage of the usually mild month of March. – A description of Thlaspis, a list of seeds and questions on Cynanchus and Asclepiades conclude that part.

Jacquin corrects a misprint in a recent work by him, (Jacquin refers presumably to Enumeratio systematica plantarumJacquin, Nicolaus Joseph, baron von
Enumeratio systematica
plantarum, quas in insulis Caribaeis
vicinaque Americes continente detexit

), already sent to Linnaeus (7 August 1760Letter L2779), and complains that he had a major work ready to be printed but that he had no money for the cutting of the more than 200 illustrations in natural size that would illustrate it (Jacquin refers presumably to his forthcoming Hortus botanicus VindobonensisJacquin, Nicolaus Joseph, baron von

The letter concludes with descriptions of some animals: a bird, Fringilla, two different species of ducks, Anas, three birds Fulica, an animal Sciurus, a monkey, Simia, and one bird said to be like Coracia garrula. The last mentioned had a beak 1.5 inches long and slightly curved, and it only ate raw meat. The descriptions of these birds are in the same general layout and content as those in the preceding letter, and Jacquin promises to send more of the same nature.

Jacquin reminds Linnaeus again about the promised seeds and also about a specimen of a dried Linnaea.
