mens in herbaria may account for the way in which the plant was 

 excluded from botanical literature by later authors ; an examina- 

 tion of the original specimens of the plant in question, however, 

 shows that it is not a Melothna in the modern sense and hereafter 

 may be known as 



Cayaponia grandifolia (T. & G.). 



Melothna grandifolia T. & G. Fl. N. A. i : 541. 1840. 



The species is closely related to Cayaponia Boykinii of the 

 Southern States, but differs in the more robust habit, the larger 

 leaves and in the larger and more elongated fruit.
