upSUMMARY

Linnaeus expresses his thanks for the letter of 20 January 1761Letter L2855, which arrived the day before. 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.
can be sure that Linnaeus will not publish anything by Jacquin without making the proper credit.

Some varieties of Aloe are difficult to define. Do they belong to Hyacinthus, to Aloe or somewhere else?

On Juncus, Linnaeus reports some similarities with what he once saw and collected in Lapland but which he then could not examine very carefully.

He asks what Jacquin means by the note on Rhamnus polygamus in the previous letter.

Among other botanical notes, Linnaeus asks Jacquin not to forget to send seeds of Cherleria and to examine its flower carefully. He wonders about the habitat of Utricularia. He guesses that it comes from the European Alps. For the number of stamens in Portulaca triangularis which could decide the relation between the genders Portulaca and Anacampsertes Linnaeus wants to combine the two, but several others have asked him to treat them separately.

A list of 30 new genera is given, the characters of which Linnaeus is very eager to see in a new work by Jacquin. Linnaeus wants to have them in the main body of Systema naturae [the next published edition was Systema naturae, 12th editionLinnaeus, Carl Systema
naturae
, 12th edition (Stockholm
1766-1768). Soulsby no. 62.
] but will not do so without being able to refer to a published work; otherwise, they will have to go into the appendices, which Linnaeus thinks is a poorer alternative.

Linnaeus answers Jacquin’s offer of seeds of Hibiscus and other plants.

Linnaeus has heard that the Emperor Franz IFranz I, (1708-1765).
Austrian. Reigned from 1745-1765.
in Vienna has many new birds in cages, so he wants to know what they are. – Giovanni Antonio ScopoliScopoli, Giovanni Antonio
(1723-1788). Italian. Physician and
naturalist. Correspondent of Linnaeus.
has written to Linnaeus [1 September 1760Letter L2798] and said that he has sent a copy of his work [Linnaeus refers to Flora CarniolicaScopoli, Giovanni Antonio
Flora Carniolica exhibens plantas
Carniolae indigenas et distributas in
classes naturales. Cum differentiis
specificis, synonymis recentiorum, locis
natalibus, nominibus incolarum,
observationibus selectis, viribus

(Vienna 1760).
] together with the letter. But the book had not arrived. Linnaeus is very eager to have it. – Linnaeus sends his regards to Franz von MygindMygind, Franz von
(c.1710-1789). Danish/Austrian.

Vienna. Correspondent of Linnaeus.
and asks to be sent seeds of his Drypis.

A short comment on the pigeons: a pity they do not brood. Linnaeus can not tell their names, since the descriptions are too brief.

Linnaeus reports on his days in order to defend his long delays in answering Jacquin: He has five hours of lectures each day in the morning, one of which is public, the others are given to private groups. Afterwards, he corrects proofs, makes new texts for the printer, writes letters, cultivates the garden and his farm, etc., so his days are very full. Jacquin would feel sorry if he saw Linnaeus, so busy is he with his large family and his many friends, students and visiting colleagues. – But Linnaeus will pay more attention to Jacquin’s material from now on.
