1 In the neighborhood of Miami Mr. G. L. Fawcett, scientific assistant in plant pathology, Department of Agriculture, has no- 

 ticed two distinct forms of Picramnia pentandra, one with narrower darker green leaflets more attenuated at the ends, dark red 

 or maroon fruit usually about 9 millimetres long, and light gray branches. On the other form the leaflets are broader and light 

 green; the fruit is bright red, often 1.3 centimetres in length, and is borne on stouter pedicels, and the branches are light brown.
