Jacquin wants more clarification on why Linnaeus said that one of the plates was of Euphorbia canescens, while Jacquin had thought it to be Euphorbia maculata. He sends small twigs of some variants and asks Linnaeus to inform him.
Jacquin agrees in principle with Linnaeus on Arnica Doronica but gets an opportunity to ask Linnaeus whether he should believe in Systema naturae, with Mantissa, (Jacquin refers to Systema naturae, 12th editionLinnaeus, Carl Systema
Linnaeus has referred to a plate with Georg Christian von OederOeder, Georg Christian von
Antoine GouanGouan, Antoine (1733-1821).
Jacquin sends seeds of Evonymus verrucosus, Bryonia alba, a new species, with red berries, but the name Bryonia alba is old, and a twig of an 8 feet high bush from South Africa, similar to Crotalaria laburnifolia.
Five more plates are sent, among them Athamanta, which could be the one Linnaeus called Athamanta condensata.
Since Jacquin wants to give a full description of all Umbelliferae, he lists more than 50 species of them and asks Linnaeus to send him seeds of as many of those as possible.
