Nathaniel John Winch, Flora of Northumberland and Durham (1838)
“ At the same time I must agree with you, that modern Botanists are carrying their ideas of division and subdivision to a most unwarrantable length, and that they are thereby doing an injury rather than a benefit to science, and are deterring many from undertaking the study altogether. I must not be supposed to condemn the subdivision of genera on every occasion. If there is a distinction in the habit of the plant, and a different mode of fructification at the same time, then I will allow the genus may be a good one. ”
