An ancient French pear of unknown origin. Writing of it in 1586 Jacques Daléchamp thought it identical with the pear Nard, of the Greeks. This, however, has not been substantiated; but the pear was in early times spread generally through France under a variety of local names. One Jehan de Meung, a poet born near Orléans in 1280, wrote of it, as also did Gilles Ménage in 1694 who said it was “a kind of pears so called because of their hardness, their whiteness and their taste of rose.” It is probable that it takes its name Cailleau, Calliot, Caillou, Caillorosar, Caillot, from the caillou, a pebble, because of the grit with which it is filled. Fruit medium, globular-oblate, yellowish, with stains of fawn-russet, washed with tender rose on the side of the sun and streaked with the same color around the stem; flesh white, scented, a little coarse, semi-melting, always gritty around the core; juice sufficient, sugary, acid, musky; second; Sept.
