TT WAS reported in a previous paper (3) that there was •*• no relation between photosynthesis and the numbers, lengths, and a r rangement of stomata in a leaf. These data were for species with rates of 20 to 60 mg. CO2 dm.~hr.-!. Species with stomata on only the lower surface of a leaf had photosynthetic rates of 5 to 15 mg. CO2 dm.—hr. — ; among these species stomatal arrangement seemed to be limiting rates. In recent studies with cotton and soybeans, it was observed that numbers of stomata in the top surface of a leaf were much less than in leaves of species studied previously. Thus it seemed desirable to repeat the previous experiments, in hopes of clarifying how number of stomata in the top surface of a leaf can become limiting.
