(Sow.) Fr.) August 19, 1911, Abajo Mts. near West Mountain,

On • Philad el phus occidentals A. Nels. : 222 7, I. ( Aecidium 
gracilens Peck). August 11, 1911, Dry Wash south of Abajo 
Mts., San Juan Co. ; alt. about 2,348 m. The neighboring trees 
of Juniperns monosperma were abundantly affected with the galls 
of a defunct Gymnosporangium. The peridia of the aecia of this 
species are bright orange-yellow when first collected, but fade 
rapidly upon drying. This is the first record of the occurrence of 
the aecial stage of this species in the state. A record of the col- 
lection of the telia on Juniperns utahensis (Engelm.) Lemmon in 
Utah is given in N. A. Flora 7: 201. 1912.

On fruit of Amelanchier alnifolia Nutt.: 2225, August 11, 
1911, Dry Wash near Abajo Mts., San Juan Co., alt. about 2,136 
m. Several trees of fairly good size bore a profusion of fruit, 
and scarcely a single fruit had escaped infection. The material 
was in fine condition. Professor Charles P. Smith also collected 
very fine material of this in Dry Canyon, Cache County, on the 
same host, Aug. 8, 1909. Still another collection in my herbarium 
is that made by Mrs. Mary Strong Clemens, August 15, 1911, at 
the mouth of the Weber river.
