Contributions No. 12, p. 32, and confined to C. Nuttallii and 
Parryi and placed as a section of Cogswellia. The rest of the 
species should be placed in Eucogswellia section and next in 
generic relationship to Cymopterus as I have placed them on 
page 33. 
So far as the work on the Umbelliferx criticised by me is 
concerned Mr. Rose has not been in the.west only as far as 
Wyoming, and then only once, and recently in a part of Ari- 
those who create so many species from purely selfish motives, it 
might be inferred that I also included Coulter and Rose among 
to go over their work critically, which I would not have 
done had I believed otherwise. ey 
Mr. Rose, in ‘speaking of my new gentts Cusickia, is un- 
able to see any generic character in Cusickia minor, stating 
that I have not given any. If he will take the trouble to read 
over his generic character for Leptotcnia and my character for 
Cusickia he will find them differing far more than any genera 
he has created, or if he does not others can. fees
