thanks Linnaeus for the letter of 25 August 1773Letter L4876.

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
, 12th edition (Stockholm
1766-1768). Soulsby no. 62.
or Genera plantarum [...] editio sextaLinnaeus, Carl Genera
plantarum [...] editio sexta ab auctore

when they differ.

Linnaeus has referred to a plate with Georg Christian von OederOeder, Georg Christian von

and economist. Studied under Albrecht
von Haller in Göttingen and became
professor of botany at Copenhagen.

for Gentiana ciliata, but Jacquinís Gentiana ciliata does not look like that and must be a new species. Is Linnaeusís citation correct?

French. Botanist, Montpellier. Student
under Sauvages. Director of the
botanical garden in 1767, later
professor of botany and medicine.
Although an admirer of Linnaeus he tried
to develop a hybrid of his system of
classification. Correspondent of
has said that Linnaeusís Laserpitium chironium and Pastinaca Opoponax are the same species. Is that really so?

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.
