Peter Collinson had lent his copy of Species plantarum to a celebrated botanist [presumably the Earl of Bute [John Stuart] and when he received it back, the borrower had made a critical comment:
The borrower has studied the work carefully, but he finds it the most careless of Linnaeus’s works. Linnaeus is so vain that he thinks he can dictate to the entire world. Synonyms are strangely confused, which shows Linnaeus’s want of knowledge, and the way he applies them in many instances to various plants is a proof of his lack of attention.
