been worked over with any degree of thoroughness. The high 
Sierras, the Yosemite region, the Shasta region, the mountains of 
the Coast range, and the entire Southern half of California, with 
one or two solitary exceptions, have thus far yielded no species of 
this group of plants. Except for a few scattering species from 
Oregon and Washington little is known of the hepatic flora of these 
vast areas that ought to be exceedingly prolific. The Northern 
portion of Idaho has been more fully explored by Mr. Leiberg, who 
is constantly sending interesting material. The rich and varied 
flora of the higher plants of the Pacific States has had the effect to 
withdraw attention from the equally interesting but less conspicuous 
cryptogams. The Government surveys of British Columbia have, 
through the agency of Prof. Macoun, brought to light many new 
forms from this region. 
The foundation for this list rests on many sources of informa- 
tion. The published lists of Bolander,’ Stephani‘ and Pearson,® 
have been utilized, as well as the MSS. prepared for the Botany of 
California which Dr. Sereno Watson generously placed in my hands 
in 1883 with permission to use it as I saw fit. This was prepared 
by Dr. Watson, with some assistance from C. F. Austin shortly 
before the death of the latter.© As Mr. Austin possessed the largest 
collection of American Hepaticze in existence at that time, his notes 
on the margins of the MSS. supply some deficiencies and verify 
numerous conjectures. 
In addition to the literature mentioned above, specimens of hepa- 
tics from the Gray Herbarium at Cambridge, the Torrey Herbarium 
at Columbia College, and the Collections of the California Academy 
of Sciences, have furnished some data. In the Gray Herbarium 
are drawings by Dr. Gottsche of several Californian species sent by

that his collection left this country notwithstanding the fact that it has fallen into 
excellent hands.
