The species on which the genus was founded by Arnott ; it was 

 discovered in 1833 by Mr. Hardy B. Groom, a planter and amateur 

 botanist of North Carolina, on the bluffs of the Appalachicola river 

 opposite the town of Aspalaga in north-west Florida, where it is 

 confined to a narrow strip extending about forty miles on the eastern 

 bank of the river. Although it is said to be hardy as far north as 

 eastern Massachusetts, it is still virtually unknown in British gardens, 

 and from its geographical position it cannot be expected to withstand 

 the severe winters that occur at intervals in this country.
