cells; perichaetial leaves surrounding the capsules, ovate-lanceolate; 
capsules, small, broader than long, cupuliform when old; lid persist- 
ent on the columella, bordered with red; peristome none, mouth 
bordered ; spores .048-.054 mm., green with a minutely roughened 
coat, maturing in August and September. 
“Spokane Falls, Washington Territory, collected by Sereno 
Watson, September 24, 1870.” Presumably the same specimens 
are referred to in the manual under G. Scouleri, Miiller, as being 
abundant. Distributed with the plants collected on Clarence 
King’s Expedition on the Exploration of the 4oth Parallel. 
Since collected by Marshall A. Howe on rocks just above the 
water in the Sacramento River, Sims, Shasta county, Cal., August 
IO, 1894. 
Closely allied to S. Patagonica, but the marginal cells are less 
dense, often only one layer of cells, but larger and square in 
section.

This tree can now be added to the flora of Georgia. Formerly 
it was known only from the Carolinas and Virginia. There it 
grew at altitudes ranging from 2,100—5,000 feet. I found it in 
1893 growing on the southern ledges of the cafion at Tallulah 
Falls, thus extending its range many miles to the south and its 
altitude to 1,600 feet. It was most plentiful about 300-400 feet 
above the river and reached no great development on account of 
the scarcity of soil and the perpendicular position of its place of 
growth. As was the case in all the other localities where I saw
