1755 at the order of emperor Franz I of

for his beautiful drawings of flowers.

Among several shorter botanical notes, some are more elaborated:

Ayenia is a specimen of a variety received through Pehr LöflingLöfling, Pehr (1729-1756).
Swedish. Botanist and explorer. Studied
under Linnaeus. Went to Spain in 1751
and took part in the Spanish expedition

and not the normal one. The proof for that is found in some minor details of the petals.

Also for Aralia, a discussion on precise details is performed, illustrating the difference between Jacquin’s and one described by Patrick BrowneBrowne, Patrick (1720-1790).
Irish. Botanist who made six voyages to
the West Indies. In 1756 he published
The Civil and natural history of
Jamaica

[Linnaeus presumably refers to 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
body
(London 1756).

Linnaeus is eager to see a living plant from an American seed and asks Jacquin for more such seeds in addition to the four sets he has already got. Linnaeus promises Jacquin refunding for mail expense but stresses that spring is coming, after which it is too late to sow.

Linnaeus gives Jacquin some advice on how to proceed in the diagnosis of Umbellatae, especially on the importance of the involucre. Another basic question is taken up, the importance of the pericarp to constitute a new genus. Linnaeus does not like to answer that in writing but would prefer to expand on these things orally in a demonstration. However, he refers back to what he said in Philosophia botanicaLinnaeus, Carl Philosophia
botanica, in qua explicantur fundamenta
botanica cum definitionibus partium,
