Some Mammoth Specimens
At the left, a selected specimen of the common almond; in the center, the Palestine almond; at the right a specimen of the "big fat" almond, the latter obviously well named. Note the characteristic texture of the shell, which does not vary greatly in these specimens, but which differs markedly from that of all other stone frults.
