Our eastern plant agrees very closely with the European E. 



myosuroides \ but the western form referred to this species is quite 



different in a number of characters and I believe it should all be 



referred to JL stoloniferum (Hook). The only western specimen 



examined that seemed at all doubtful was from Guadalupe Island, 



Lower California, collected by Edward Palmer (no. IX 5) in 1875. 



The circumstances were such that the accuracy of this label is 

 doubted. 



An exceedingly variable species especially in leaf characters ; 

 var. filescens Ren. & Card, is a slender form with branches often 

 Hagelliform. For the distinctions between this species and E. 

 stoloniferum see notes under that species.
