so he makes it a new species.

The plant from the island Borbonia in the West Indies will be described when it has got flowers, as Jacquin already knows the anatomy of its fruit.

After a comment on Seseli multicaule, ending in a request for seeds of Seseli elatum, Jacquin tells Linnaeus that he can not send seeds of Filago Leontopodius There were no seeds from his specimens the preceding autumn, but there may be in the next year instead.

Jacquin sends seeds of Silene alpestris, which is not the same as Silene quadrifida. He corrects information given by Antonio ScopoliScopoli, Giovanni Antonio

After a short discussion on Veronica latifolia, Jacquin describes a plate of a very common Austrian plant that can be identified with several species found with earlier scholars. Jacquin wants Linnaeus’s opinion and somewhat urgently, since he is about to print his text.
