Pæonies From Langport.
A boxful of named varieties has reached us from Messrs. Kelway and Son, Langport, Somerset. [...] None of the double varieties was entirely white, though there were several pale and choice varieties. [...] The darkest of all sent us was a new one named General Buller, having rather shortly stalked but healthy foliage, and a large carmine-rose flower more or less flushed with a silvery tint at the tips of the central petals.
