N°* 5739- August 4, Fish Lake, Utah, 9000 alt., in 



On Pentstemon confertus var. uvruleo-purpureus. 

 No. 5oi5bg. September 7, Panguitch Lake, Utah, 

 8400° alt. 

 Same host.

No. 6oo2ax. September 6, Panguitch Lake, Utah, 

 8400° alt. 



Same host. 



No. 6oi5bg. 



Same host, cecidia found on No. 5739 and 6oi5bg are 

 the same as SEcidium Palmer i And., and while the teleu- 

 tospores on No. 6oo2ax and 6oi5bg differ slightly from 

 the description given by Peck, they undoubtedly belong 

 to his species. No. 6oi5bg has the three forms well de- 

 veloped on the same leaves, and as we find no description 

 of the uredo-spores, we make the following: 



Puccinia Pcntstcu, >///$ Peck. Amphigenous. I. Spots 

 and spermagonia wanting; pseudosporidia usually single, 

 but sometimes in small clusters, three or four times as 

 long as broad, and from a much thickened base, which Is 

 often bright purple, upper part bright yellow, becoming 

 white at maturity and splitting nearly or quite to the base; 

 spores subglobose or oval, contents granular, epispore 

 thick, slightly echinulate, 18-20x20-22 m. II, III. Sori 

 small, round, scattered, nearly black; uredo-spores in 

 the sori with the teleutospores, globose or oval, smooth. 

 15-18x18-26 m. Teleutospores broadly oval, somewhat 

 epispore smooth, slightly but distinctly
