lanceolatum et linearifolium A, Gray, 1846.) California, New 
exico, Texas, Mexico, Chili. This species differs undoubtedly 
from J. alatum, the latter being well characterized by its large 
hypogynous ring and the form of its leaves. This ring of the 
dimorphous Lythra has been overlooked before by all botanists. 
ave dissected numerous flowers for the purpose of ascertaining 
the diagnostie value of the ring, and I have found that it is ab- 
solutely constant in form and size,
