and comments on several of them.

Potentilla caulescens: The plate gives a reason to define the difference between that depicted, identical to a variant known from Switzerland through Albrecht von HallerHaller, Albrecht von

, and one called Potentilla Clusiana. One major difference is the location: Potentilla Clusiana mainly grows in the highest parts of the Alps.

Lycoperdon ramosum grows in decaying wood. Jacquin explains what parts and details are depicted in the plate.

Vicia militans Cranzii is clearly not published by Linnaeus. For another, Vicia segetum, Linnaeus had suggested identifying it with Vicia cracca, but Jacquin does not agree. Jacquin indicates several important differences and asks Linnaeus to reconsider the issue carefully before telling him his conclusion.

Jacquin sends some seeds of Hasselquistia and Canellaria, which Linnaeus had asked for, and dried specimens of Lepidium alpinum, of Lepidium petraeum and of an unknown plant, grown from seeds received without a name tag.

Jacquin tells Linnaeus that 30 Chemnitzian gold ducats correspond to about 31 Belgian ones. He seems satisfied with the arrangement for the payment and congratulates Linnaeus on his recovery from the stroke.

is finished, and Jacquin will send it to Linnaeus as soon as possible.
