and is like a gem of deep blue-green color in a setting of lofty, 

 jagged mountains, whose lower parts are good farms well watered 

 by countless falls and brimming brooks. The other is Gudvan- 

 gen and Stalheim, which we reached by driving eight miles up 

 the Naeroedal, a valley at the base of mountains 4,000-5,000 ft. 

 almost sheer from sea level, and so close together that our necks 

 ached with the effort of seeing their summits. At the end of 

 the drive we walked up the winding road to the Stalheim cliff 

 and hotel, from which we had a fine view down the narrow val- 

 ley and the many mountains one behind the other until they 

 faded into the blue distance. Those two places were a fitting 

 conclusion to a most interesting journey and are within easy 

 reach of Bergen. In the little botanical garden in Bergen I 

 found in flower and named some of the plants I had noticed in 

 the yard of the man in Reykajavik. 



I am indebted to Mr. Rydberg for naming the plants I brought 

 back, which are now in the New York Botanical Garden 

 herbarium. 



NOTES ON UROMYCES 



By John L. Sheldon 



In the spring of 1906, I found an Uromyccs on a number of 

 plants of Sisyrinchium gvaminoides Bick., usually associated with 

 Aecidium houstoniatuni Schw. on Hoiistonia caeridea L. Men- 

 tion has been made of this in a previous number of Torreya,^ 

 together with a description of the Uromyces and the results ob- 

 tained from inoculations made in the field. Observations and 

 inoculation have been kept up for the past three years. Suc- 

 cessful inoculations of plants of Sisyrinchiian graminoides, with 

 aecidiospores from Houstonia ccBvulea, have been obtained each 

 year. During the winter and spring of 1907, I finally succeeded 

 in obtaining aecidia on a few plants of Houstoida caendea, grown 

 in the greenhouse and inoculated with teleutospores from Sisy- 

 rinchium graminoides. These results showed that the Uromyces 

 and the Aecidium are different stages of the same rust. And
