By continued growth the apical cell retains, despite its repeated divisions, its oi-igi- nal dimensions. 50.—The growing cells of the stem of the English bean ( Vicia faba) furnish a good illustration of fission in the highest plants. In this case, and in many other, if not all, Dicotyledons, the division takes place directly cf'Jf^Wrtoprre^sVLSonTS through the Centrally placed fa?lie^"'lgi rat'^itrcTpllU"!
