plate of Verbena. He should make another, with significant features more prominently displayed.

In another plate, no 177, there is a species totally unknown to Linnaeus. He does not dare to include it into his system without seeing a living plant or a complete dried specimen, so Jacquin should send him seeds or a sample.

Jacquin should not include the Hieracium in his publication before having it for a year in his garden. Linnaeus had noticed that they change very much when cultivated outside their natural habitat, the Alps.

Linnaeus has got more than 1,000 species from the Cape of Good Hope region and has been very busy with them all summer.

Linnaeus makes comments on five other species.
