"The common carline thistle, the centaury star thistle, and the stemless plume-thistle infest pastures with sandy or calcareous soils oftener than clayey or grass lands... The marsh plume-thistle, the various - leaved plume-thistle, and the meadow-plume thistle prevail most in loamy and clayey soils; and must be dealt with in the manner of other perennial thistles."
