physician, Bordeaux. Correspondent of
letter [Aymen to Linnaeus, 24 November 1753Letter L1665] from Paris and thanks him for that.

He is pleased that Aymen has gone to Paris, where he can learn very much, particularly from Bernard de Jussieu’sJussieu, Bernard de

botany, brother of Antoine and Joseph de
Jussieu. Demonstrator at the Jardin des
plantes. Sébastien Vaillant’s
successor. Uncle of Antoine Laurent de
Jussieu. Correspondent of Linnaeus.
. He asks Aymen to forward his regards to Jussieu.

Linnaeus also thanks Aymen for the information on various plants and makes several detailed questions on other species, especially those that are found in the Paris garden. On others, Linnaeus admits that he has not seen specimens before so that he does not know them.

Linnaeus had ordered a copy of Species plantarumLinnaeus, Carl Species

to be sent to Jussieu through the French embassy in Stockholm, and he is surprised that it has not yet reached Jussieu.

Linnaeus asks for seeds of Zizania and for advice on how they should be planted.

Linnaeus reports on his work in compiling lists of species for various regions – Sweden [Flora Svecica 2nd ed.Linnaeus, Carl Flora Svecica

Linnaeus comments on different detailed issues in species and in botanical literature.

He does not agree with the majority of botanists over the definitions of genera in Rhamnus.

He is very critical of Albrecht von HallerHaller, Albrecht von
