 immature condition of the material, it could not be named with 

 certainty.

On Gilia Nuttallii A. Gray: 268, I, Aug. 13, 1903, Big Cotton- 

 wood Canyon near Lake Catherine, 9,600 feet; 5/0, I, III, 

 Aug. 27, 1904, Big Cottonwood Canyon, 9,525 feet. On Micro- 

 steris micrantha (Kellogg) Greene, {Collomia gracilis Douglas) : 

 J<^7, III, May 2, 1903, Salt Lake City; 2061, Aug. 2, 1909, 

 Fish Creek Canyon, western Sevier Co. So far the writer has 

 failed to find aecia on this host, the telial stage being contem- 

 poraneous with the aecia on Phlox. Moreover, the telia on 

 Microsteris are very confluent often continuously occupying the 

 the entire stem, a habit not found on the other hosts. Then too, 

 Microsteris is an annual, and the aecial mycelium on Phlox is 

 doubtless a perennial, as is evidenced by the hypertrophied leaves 

 of the host and by the strong " slippery-elm " odor of the aecia. 

 The form on Microsteris is probably a distinct species which pro- 

 duces telia only. On Phlox longifolia Nutt. : 168, I, on leaves 

 of the new growth, April 25, 1903, Salt Lake City; 212, III, June 

 12, 1903, Salt Lake City. 



An abundant species. Type collected by M. E. Jones in Utah.
