THREE BRANCH ZONES IN THE EGYPTIAN COTTON PLANT. 9 base of the stalk, which usually produce from 6 to 10 limbs. Theextent of this zone varies in different individuals. Limbs may de-velop as high as the twelfth or even the fourteenth node, but this israther an extreme limit. ZONE OF RUDIMENTARY BRANCHES, OR TRANSITION ZONE.
