bracts being smooth or even approaching the short-tubercled con- 
dition of A. obovata) that it may be known as

This variety is often well marked, differing from the oe form 
in the nearly oblong leaves and triangular-cuneate usually irreg- 
ularly dentate bracts. Since intermediate forms are not infre- 
quent, however, as for instance Aven Nelson’s no. 3667 from 
Sweetwater Co., Wyo., I am inclined to treat the plant as rep- 
resenting only a variety of A. Gardneri.

The genus Endolepis differs from the type species of the genus 
Atriplex only by the presence of a perianth in all of the pistillate 
flowers, this being absent in some of the pistillate flowers of true 
Atriplicas: If this character is of generic value how can Standley, 
maintaining Endolepis, consistently regard species of Atriplex 
having all the pistillate flowers without a perianth as belonging to 
the genus Atriplex? Yet he follows this obviously illogical reason- 
ing in his interpretation of the genus Atriplez, |. c. 33. By all 
means let us have another genus to care for the 101 species in 
North America (according to Standley’s treatment) referable to 
neither true Atriplex nor Endolepis for exactly the same reason, as 
indicated above.
