Jacquin had formerly identified a Euphorbia as being Euphorbia verrucosa. He does not think so any more. An elaborate description in words is given, and he asks for Linnaeusís opinion.
Cacalia alpina and Cacalia tomentosa are very similar but still with important differences, so that the latter can not be a variant of the former. That had previously been the opinion of most scholars, among them also Linnaeus. Jacquin specifies his view on the differences.
Three specimens of Silene are depicted in one plate, since the plant varies so much. Jacquin thinks the species is Silene conica, but he wants that theory confirmed. Also, he asks for seeds of Silene conoidea.
Jacquin has received Linnaeusís letter of 10 January 1775Letter L5071 and reports that Campanula Sibirica generally looks like that in Austria.
The letter ends with a number of short remarks on various species, including one on Vicia cracca where Jacquin does not agree with Linnaeus.
Jacquin has received the money for the books sent to Uppsala.
