tion, the type of this would be no. 484, collected on the Wahsatch 

 mountains, Utah, August, 1869, altitude 8000 feet. But on the 

 same sheet in the Columbia University Herbarium, and under the 

 same number, 484, are two other specimens, which are not of this 

 species. One was collected on the Wahsatch mountains, Utah,

Specimens which appear to belong with this species, were col- 

 lected by Dr. D. T. MacDougal, in the Grand Canon of the 

 Colorado, Arizona, June 28, 1898, no. 188. Why Dr. Gray 

 changed the name of this plant when he raised it to specific rank, 

 is not apparent, as the varietal name seems to be perfectly valid. 

 While looking up the original description and synonomy of this 

 plant, I discovered that two other species bear names which are 

 untenable :

Erigeron stenophyllus A. Gray, Pac. R. R. Surv. (Whipple 

 Expedition) 4: 98. 1857. Not Erigeron stenophyllus H. & A. 

 1836, nor Erigeron stenophyllus Nutt. 1847. 



The type of this was collected "on hillsides and steep banks 

 of the Pecos ; October," by Dr. J. M. Bigelow. The particular 

 place meant is the ford of the Pecos in New Mexico, on the Santa 

 Fe trail, not far from where the Santa Fe railroad now crosses the 



stream.
