Orthography 



1. When we merged files that were the basis for this 

 checklist, all trinomials were arbitrarily assigned to be 

 varieties from lists where rank was unspecified. Some of 

 these trinomials were actually subspecies, and most 

 were later caught and their ranks corrected. Two 

 others that should have been deleted are: 



a. Brodiaea terrestris var. kernensis 



b. Salicornia europaea var. rubra 



2. Spelling errors 



a. Polygonum triandrum, not P. triandrus nor the 

 original "P. triandrous" (sic). 



b. Viola eriocarpa, not V. eriocarpon 



c. Viola pubescens var. eriocarpa, not V . pubescens 

 var. eriocarpon (the original spelling) 



d. Elliotlia pyroliflora, not E. pyroliflorus 



e. Nierembergia hippomanica var. caerulea, not 

 N. h. var. coerulea
