Link: • Henri-Louis Duhamel Du Monceau to Carl Linnaeus, 29 January 1764 n.s.
Dated 29 Janvier 1764. Sent from Paris (France) to Uppsala (Sweden). Written in French.


Henri-Louis Duhamel du Monceau has received Linnaeus’s letter [this letter has not come down to us] and he informed the Academy of sciences in Paris [Académie royale des sciences, Paris Académie royale des sciences,
French. The French

in 1666 and became a royal academy in

] at once so that an extract from it could be introduced into the Register. Linnaeus had also enclosed a tea leaf, and an officer who had gone to China for a long time [Linnaeus most certainly meant Carl Gustaf EkebergEkeberg, Carl Gustaf

] had told him that this tree easily propagates. If Linnaeus could make this plant common botanists would owe him thanks once more.

Duhamel has postponed his answer because a Frenchman just received tea from China. Duhamel had been waiting to see its leaves but without doubt this must be the Psoralaea.

Linnaeus mentioned in his letter that he had thought of the possibility of receiving this plant alive in spite of the tropical heat. Duhamel has received from his correspondents fresh seeds that germinated and even began to sprout in moss or earth.

Duhamel has sent to Linnaeus all his works on forests. He knows that Linnaeus has received the work on trees and shrubs [Duhamel refers to his Traité des arbres et arbustesDuhamel Du Monceau, Henri-Louis

sends his regards.

P.S. Duhamel says that he has heard that a variety of Sorbus aucuparia can be found in the neighbourhood of Uppsala and supposes that Linnaeus has mentioned that in his Genera [Duhamel presumably refers to the fifth edition, Genera plantarum [...] editio quintaLinnaeus, Carl Genera
