This species has the densely papillose leaves with strongly 
revolute margins of (Q. alpestre. It also has sub-immersed cap- 
sules, which are urceolate when old, with a flaring mouth, and 8 
striz, the teeth united in pairs, and 8 cilia which are described as 
“robust, punctate.” The calyptra is slightly hairy, but the teeth 
are described as smooth and figured without striations. 
Dr. Venturi (Musc. Gall. 163, 1887) refers this species to the’ 
- roup of Q. cupulatum near O. urnigerum var. Schubertianum, but 
Says that the description is too brief, and the specimens in his 
collection do not permit of a decision as to its specific value. 
Type locality: On damp rocks in shade, West Humboldt 
Ountains, Nevada, altitude 5,500 ft., S. Watson. We have the 
Specimens which were collected in June, 1867, and distributed as 
°- 1402, with autograph label by T. P..James. The plants are 
2 cm. tall, yellowish green with spreading leaves, 3 mm. long; the 
calyptra is brown and more hairy and less glossy than European 
specimens of QO, alpestre, or than R. S. William’s No. 96, with 
Which they were compared. The Manual says the capsules are 
without aneck. This is not true, as the striz of the capsule are 
k °ntinued down into a distinctly twisted neck. No. 1404, col- 
“cted by Watson in the Pah Ute Mountains, Nevada, in August, 
also has a little of this species mixed with two others. It was 
Collected at the same elevation, and was distributed as O. /evi- 
Saltum Zett. . i 
VI. Group or O. PUMILUM. 
In the Western States, as well as in the Eastern, this species 
its allies is but little known, and in Europe they seem to be in 
the ‘ame condition, for Dr. Venturi writes that as understood by 
and
