The type, in the herbarium of the Nevada Agricultural 

 Experiment Station, is Hellej{ loioy, collected May 26, 1910 on 

 Hood river, near Hood River, Wasco county, Oregon. The 

 plants were growing in low moist ground about a mile and a 

 half above the junction of Hood River with the Columbia. 



This is probably the L. rividaris of Piper's Flora of Wash- 

 ington, as it is one of the species that has been masquerading 

 under that name since 1873. ^^ seems to be most closely related 

 to L. latifolius. 



The following species, in addition to L. confusus, belong to 

 the Latifolii.
