Rydberg: Studies on the Rocky Mountain flora 313 



staminate plant has a few pistillate flowers borne on the lower 

 part of the branches. The predominantly pistillate plant has 

 often a few staminate clusters above but is sometimes wholly 

 pistillate. E. subspinosa grows on rocky hills in the desert 

 regions.

Dondia calceoliformis (Hook.) Rydb. comb. nov. 



Chenopodium calceoliformis Hook. Fl. Bor.-Am. 2: 126. 1838. 



This, I think, deserves specific rank. It is characterized from 

 D. depressa (Pursh) Britton and D. erecta (S. Wats.) A. Nels. by 

 its broad and short, ovate or ovate-lanceolate bracts over 2 mm. 

 wide. 



AMARANTHACEAE 

 Amaranthus pubescens (Uline & Bray) Rydb. comb. nov. 



Amaranthus graecizans pubescens Uline & Bray, Bot. Gaz. 19: 317. 



1894. 



This probably deserves specific rank. It has been collected 

 in Colorado. 



Amaranthus carneus Greene and A. californicus S. W T ats. 

 should be added to the region. The former has been collected in 

 Montana, and both in Idaho.
