False botanists

... says Linnaeus:

False BOTANISTS proclaim the Laws of the Art before they have learned them:
Extol absurd Authors, and are jealous of the excellent ones:
Steal from others, producing nothing of their own:
Boast much of a little knowledge:
Pretend they have discovered a natural Method:
Assert the Genera to be arbitrary. [System Vegetabilis 1774, §27]

I wonder who he is talking about.
