Warea,* making the type a Warea amplexifolia founded ona 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.
