P. Haydeni was collected in an entirely different rej^^ion, in 

 Kick Bottoms, Jackson Hole, Snake river, Wyoming, at an ele- 

 vation of 60 DO feet, June 15, i860, by Dr. Haydcn, on Captain 

 Reynold's expedition. Our plant, /'. tnontrosense, is an alpine 

 plant, and so far as we know, does not grow below 9500 feet 

 elevation. 



There is a probability that P. montrosense may prove to be 

 the same as P. Tevisii, as the description answers our plant very 

 closely, and it comes from the same general region. At present 

 we do not have access to a specimen or the type of P. Tevisii. 



So far as we are aware, this beautiful little plant is not yet 

 in cultivation, and from a knowledge of its growth and habitat 

 we feel sure that it is adapted for rockeries, and should be in 

 every collection of alpine plants. The photograph was taken at 

 the type locality, at an elevation of 10800 feet on Mt. Rose, 

 Washoe connt\-, Nevada, where it was orowiug in the crevices 

 of lava rocks.
