Dated XXX Aprilis 1764. Sent from Wien (Austria) to (). Written in Latin.


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.
received Linnaeusís letter of 1 April 1764Letter L3397 two days before. He is surprised that his letter of 18 September 1763Letter L3294 had been in the mail so long and that Linnaeus has not got the letter he sent 4 February 1764Letter L3375 in answer to that from Linnaeus of 4 January 1764Letter L3366. And Jacquin has not received the letter Linnaeus says he sent with the answering list of the species sent through Laurens Theodor GronoviusGronovius, Laurens Theodor
(1730-1777). Dutch. Naturalist. Senator
of Leiden. Son of Johan Frederik
Gronovius. Correspondent of Linnaeus.

Jacquin is also struck by the close similarity of Scopola Carniolica with Atropa belladonna. Giovanni Antonio ScopoliScopoli, Giovanni Antonio
(1723-1788). Italian. Physician and
naturalist. Correspondent of Linnaeus.
has sent many seeds to Jacquin, but none has germinated. Scopoli had said that he had found them not yet mature but Jacquin has found them all empty. It does not give seeds in the garden, because all capsules fall off. It is easy to cultivate and propagate from the root, though.

Jacquin has never seen Peloria, and he does not ask Linnaeus for a specimen since he did not succeed in getting dried plants from Linnaeus even when there was an open way for the mail through Holland. But what is to be done on Atropa belladonna when all plants just give empty seeds? Jacquin has not thought it to be a new genus but leaves it to others to decide and describe. The matter of the name is not so important. Atropa, Scopola, Hyoscyamus, all may work, as long as the identity and the character of the plant is consistent and you do not give it a name already taken for another species.

Jacquin congratulates Linnaeus on the tea bush and makes some comments on Polypodiumas a follow-up on the previous letters.

Jacquin has just published in Vienna, part 1 of Observationum botanicorum [...] pars I-IV et ultimaJacquin, Nicolaus Joseph, baron von

(Vienna 1764-1771).
with pictures of 25 species. A list of these is given. A rough outline of the contents of part 2 is also provided.

Some fifteen species among those sent through Gronovius are again asked about. The letter continues with a list of some twenty detailed questions and comments on various species and their treatment by Linnaeus and others. Jacquin ends with a promise to send material, especially since he expects a delivery of ferns, mosses and grasses from a friend in Martinique.
