JVarea* makingthe type a Warea ainplcxifoliaiowndQd on a plant 

 from western Florida. This plant had sessile leaves, according 

 to the author and his plate. Nuttall was not as shrewd as usual, 

 and failing to see that his Warea amplexifolia was different from 

 Stanleya amplexifolia, combined the original description of Stanleya 

 amplexifolia with that of Warea amplexifolia ; this blunder has 

 been followed to the present day and consequently the ambigu- 

 ous descriptions. 



The plant from eastern Florida has been represented in our 

 herbaria by good and ample specimens while only a few fragments 

 of the west Florida plant seem to be extant, but now that we are 

 furnished with excellent material the specific lines appear very 

 distinct. I append a synopsis of the genus.
