Professor Marcus E. Jones redescribed it in his Revision 

 of Aquilegia, Zoe iv, 3, 259, making the section Pseuda- 

 quilegia to contain it. The characteristics of this section 

 will have to be modified so as to also include A . niicrantha, 

 and I suggest the following: 



Pseudaquilegia — leaves triternate, spurs irregular or 

 abortive, flowers small. 



In the early part of September, 1892, I visited the type 

 locality, which is in the Ute Reservation of Colorado^ 

 about twent3^-five miles from Mancos, and collected 

 fruiting specimens which were distributed to the principal 

 herbariums of this country. Roots and seeds were also 

 obtained ; but of all that was distributed the only survivors 

 are in the garden of Mr. J. T. Henderson of Denver, 

 Colo., where they have bloomed during the past two 

 summers.
