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 (22 November 1759)Letter L2612 delivered three days earlier and states that he has got a copy of the new edition of Systema naturae (Jacquin refers to the 10th edition, 1758-1759Linnaeus, Carl Systema
, 10th edition (Stockholm
1758-1759). Soulsby no. 58.
, but without vol. 3 that may not have been published (the 10th edition was published in two volumes, “Animalia” 1758 and “Vegetabilia” 1759. The third volume, “Mineralia” was never published). He expects to find many answers there to things that he had wondered about in Patrick Browne’sBrowne, Patrick (1720-1790).
Irish. Botanist who made six voyages to
the West Indies. In 1756 he published
The Civil and natural history of
(1756). Correspondent of
writings (Jacquin presumably refers to Browne’s The Civil and natural history of JamaicaBrowne, Patrick The Civil and
natural history of Jamaica: in three
parts: containing, I. An accurate
description of that island [...] with a
brief account of its former and present
state, government, revenues, produce,
and trade: II. A history of the natural
productions [...] native fossils [...]:
III: An account of the nature of
climates in general, and their
different effects upon the human
(London 1756).

Comajandura is the first item. Jacquin has not examined a fruit; as he has already sent Linnaeus a dried flower, there is no need to send a drawing, but instead he makes a detailed description of the plant.

Jacquin corrects his earlier opinion on Breynia and refers it to Capparides just like Swietenia and Morisonia. – He is very puzzled by his Petiveria that differs from Linnaeus’s specimen. He will send Linnaeus seeds so that Linnaeus can get a living plant and compare the two. Can the difference be due to climate and soil?

On Triopteris, Jacquin compares information from various scholars: Patrick Browne, Johannes BurmanBurman, Johannes (1707-1779).

and Linnaeus. He asks Linnaeus for a leaf and a flower.

Also on Samyda, Jacquin tries to describe and eliminate a mistake that he considers to be due to the fact that the same name has different meanings in different cultures and places:Linnaeus has been misled by an error made by Browne; both Leonard PlukenetPlukenet, Leonard (1642-1706).

III). Superintendent of Hampton Court.
and Sloane are very aware of this kind of mistake.

Also in Conocarpus, Jacquin has trouble with considerable variations between Browne and Linnaeus, but he thinks it unnecessary to make them two species.

On Decandara, Jacquin asks for very specific information on the form of the pistil in Linnaeus’ specimen.

More elaborated comments or descriptions are given on Pavetta, Cedrela, Besleria, Stizolobius, Casytha in addition to a plethora of minor remarks on various plants.

Jacquin saw only a few insects on his journey, for lack of time.

Jacquin reports that Lobelia longiflora is a toxic plant that had caused him irritation in the nose, mouth and eyes for half a day after he had examined it and neglected to wash his hands before rubbing his eyes and nose. The Spaniards call it rebenta-cavallos, horse-breaker, since a horse that ate it would die from acute stomach disorder.

that Linnaeus had asked about has not yet been published, and Jacquin makes some effort to discredit both the work and its author: it will not be important, and the man is not sane. – Wilhelm Heinrich KramerKramer, Wilhelm Heinrich

, then professor of botany in Vienna, has refused to make contact with Linnaeus: he explains that Laugier is in his heart a chemist who has taken up botany for his living and that he does not want too close contacts with botanists although he had planted a garden in Vienna modelled on François Boissier de La Croix Sauvages’sSauvages, François Boissier de

Jacquin adds a list of about 20 plants, commented in various ways, and concludes the letter with information on different trees and plants with edible fruits that he had managed to grow successfully in Vienna and that had made good impressions at the Imperial Court. Seeds of Austrian plants are offered.
