All of the species listed are widely distributed in North America and Europe 
and most of them have likewise been reported from northern Asia. This is prob- 
ably due to the fact that they represent northern rather than southern genera. 
The total absence of the Jubuleae will be noted. If any of these are discovered 
in Colorado they will probably represent endemic North American species. 
Xhere is little likelihood, however, that the Jubuleae are largely represented in 
the state, although a few species of Frullania ought perhaps to be expected.

JOHN B. LEIBERG* 
John B. Leiberg was born at Malmo, Sweden, October 7th, 1853. When 
a boy of thirteen years he came to this country and at first lived in Iowa, though 
later moving further West. He had most of his formal schooling before leaving 
Sweden, but it is more accurate to say that his education never ceased, to the 
last he was eager for further knowledge, and for continued investigation. From 
boyhood he had been interested in things out of doors, and had formed the habit 
of close, accurate observation which never left him. But, like many busy men, 
he seems to have published but little. His personal character won the respect 
and affection of all who came into contact with him — as one correspondent writes, 
“He was a good man; no higher praise can be given.” 
Before 1889 he was in correspondence with Mrs. E. G. Britton. At this 
time he was living at Hope, Idaho, and studying the flora of Kootenai County. 
The results of these collections were published by Mrs. Britton in the “Bulletin 
of the Torrey Botanical Club” under the titles, “An Enumeration of the Mosses 
Collected by Mr. J. B. Leiberg in Kootenai County, Idaho” (Vol. XVI.), and 
“A Supplementary Enumeration of Mosses Collected in Idaho by J. B. Leiberg.” 
(Vol. XVIII.) Besides the annotated list of species, these papers contained the 
announcement of the first collection in fruit of Grimmia torquata Hsch., and the 
description of Hypnum ( Thamnium ) Leibergii, E. G. B., a species new to science. 
For many years Mr. Leiberg was connected with the United States Depart- 
ment of Agriculture, during which time he traveled extensively in the West, 
collecting freely wherever he went. He also spent a year in the Philippine Is- 
lands in the employ of the Bureau of Forestry, and later spent another year 
there on his own account, in the study of the flora. In 1909, accompanied by 
Mrs. Leiberg, he made a leisurely trip around the world visiting especially the 
* The following notice of Mr. Leiberg should have appeared some time since, but the news 
of his death was not received for nearly a year after the event and the pressure of other work has 
greatly delayed the collecting of even the few notes given here.
