 Among the last truly beautiful and interesting collection of 

 plants I had the pleasure to receive from my valued friend 

 Professor Jameson, is the present fine Gentiana from the alpine 

 regions of Pichincha. Several other interesting species from 

 the Colombian and Peruvian Andes will soon be described in 

 the Monograph of this family by Dr. Griesbach.
