It is well to remem-ber that though we speak of leaf blade, petiole, stems, and so forth as distinct organs, they are primarily the same, as curious freaks of nature as they may he called often teach us. Thus in a very curious species of Croton, - Croton appendiculatum, recently sent out by James Vietch & Son, of Chelsea, London, portions of the leaf blade return again to leaf stalk, and in many plants half the leaves have this apparently double leaf. Similar lessons can be found in many things if we only look sharp.
