This plant is very abundant on many of the outer Keys of the Flo- 

 ridas. It grows among other shrubs, seldom exceeding seven or eight 

 feet in height, and more frequently not more than four or five. The leaves 

 are obovate, rounded at the base, thick, glossy above, downy beneath. 

 The outer petals are larger, and not unlike the divided shell of a hickory 

 or pig nut ; the inner ovate, deep purple, with a white band at the base. 

 I did not see the fruit, which I was told is not unpalatable when ripe, it 

 being then about the size of a common walnut, and of a black colour.
