Nicolaus Joseph von Jacquin’s sends Linnaeus some plates from his material for the Vienna Botanical Garden (Jacquin refers to the Botanical Garden of the University of Vienna, founded in 1754).
One is a plate of a small tree, where Jacquin does not find even a suitable genus anywhere in Linnaeus’s works. The tree is described.
On several others, such as Anthericum asphodeloide and Potentilla caulescens, Jacquin is not sure of the attribution and asks Linnaeus to check and help. Especially, the Potentilla causes him trouble, since he has three variants which he considers to be of separate species, which is in contrast to the meaning of Albrecht von Haller.
Two Gnaphalium, Convolvulus volubilis and Chenopodium sinense are other instances where Jacquin wants Linnaeus’s help to decide if it is an unknown species or not.
Some seeds and small specimens enclosed are briefly described.
