Hagström has still not obtained the latest edition of the Genera plantarum [...] editio sextaLinnaeus, Carl Genera

Soulsby no. 305. but he is expecting it soon. Hagström continues to discuss extensively from which plants bees take their honey and wax. He feels uncertain about some species, whether they are desirable for bees or not. Therefore he sends plants to Linnaeus, in order to be certain that they are correct in his planned work [Hagström refers to his Pan apumHagström, Johan Otto Pan

af hvilka bien hälst draga deras
honung och vax; ingifven til K.

på dess fråga,

Academy of Sciences, Stockholm. Founded
in 1739. ].

P.S. 1. Hagström admits that he had been confused or mistaken considered what he wrote in his last letter on Fragaria vesca and bees.
P.S. 2. Hagström has made a list of the plants visited by bees, requiring numerous observations over several years.
P.S. 3. Hagström mentions the opinion of the head gardener at the Sturefors manor on these questions.
P.S. 4. Hagström comments that Caltha palustris did not yet have an economic observation. In previous years he had observed bees only superficially because he had believed that René-Antoine Ferchault de RéaumurRéaumur, René-Antoine
