in the study of his collections. Following this, the remaining years of his life 
were spent quietly at his home in Leaburg, Oregon, where he died the 28th of Oc- 
tober, 1913. His wife and two sons survive him. For the last few years he had 
become specially interested in the bacteria, and in the tropical epiphyllous 
lichens. Previous to his death, his large collection of flowering plants had been 
given by him to the University of Oregon. In accordance with his wishes, his 
other collections were sent to the National Herbarium at Washington. 
Besides some species of flowering plants, the following mosses have been 
named for Mr. Leiberg: Thamnium Leibergii, mentioned above, and Grimmia 
Leibergii Paris, ( G . pachyphylla Leiberg, non C. Miill.).
