upSUMMARY

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 20 March 1761Letter L2889. The delay was due to the fact that Jacquin was in Baden to collect plants from that region when the letter arrived. Like Linnaeus, he is surprised that his previous letter took about two months in the mail.

Cherleriaflowers richly in the garden, and Jacquin describes its flower in detail with its ten stamens, which are of two kinds, with five in each.

Jacquin also answers that Rhamnus Domingensis and Rhamnus polygamus should be brought to a new gender and not belong to Rhamnus at all. Jacquin proposes the name Hypselion for the gender. – He also answers the questions on Urticularia and Portulaca

This is followed by reports on various plants seen Austria or in America, e.g. Brunfelsia, Justicia. Of the latter, Jacquin has trouble with two variants, differing only in the number of anthers.

Jacquin does not know if anybody has sent Linnaeus a copy of Giovanni Antonio Scopoli’sScopoli, Giovanni Antonio
(1723-1788). Italian. Physician and
naturalist. Correspondent of Linnaeus.
work (Jacquin refers to Flora CarniolicaScopoli, Giovanni Antonio

Carniolae indigenas et distributas in
classes naturales. Cum differentiis

(Vienna 1760).
), for Scopoli could have thought that Jacquin was eager to send it. But Jacquin has not done so, nor will he, and since he has no contact with Scopoli he lacks any interest in the matter.

Jacquin had kept several birds in cages for the Emperor Franz IFranz I, (1708-1765).
Austrian. Reigned from 1745-1765.
, but now, only those brought from America are still alive. Jacquin has already told Linnaeus about these birds.

Jacquin has difficulties with the pigeons and disagrees somewhat with Linnaeus since he can not identify some of the species of pigeons mentioned by Linnaeus in Systema naturae (Jacquin refers presumably to the 10th edition, 1758-1759Linnaeus, Carl Systema
naturae
, 10th edition (Stockholm
1758-1759). Soulsby no. 58.
). This leads to a fairly detailed description of one ash-grey and one blue pigeon, the latter considerably bigger than the former.

The letter ends with promises of seeds and reports on flowering plants. A specimen of Saxifraga is enclosed; Jacquin describes it and its location and wants to know its name. – Descriptions of animals will follow. Jacquin asks for seeds of Meadiaand of rare plants and says he devotes much time to excursions in order to collect specimens of plants.
