Hab. Gravelly soil, Mount Dana, at 10,000 feet altitude (Bolander). 



Keseiubles the preceding species, but is very distinct in the haniulose 

 homomallous leaves with long subulate opaque luuticous points, in the 

 large capsule on a longer curved pedicel, the absence of annulus, etc. 



13. Gr. torquata, Grev. Soft and fragile, in dense con- 

 vex tufts, briglit green above, blackish brown below and radi- 

 culose at base: leaves erect, spreading, spirally curved when 

 dry, oblong-lanceolate, the lower blunt, the upper with a short

In one specimen the leaves are twisted and crispate at the top of the

 by nniovations from near the apex : leaves densely imbricate, 

 spreading and turning upward from the middle, erect when 

 dry, long-lanceolate, concave at the somewhat enlarged base, 

 carinate toward the apex, plane on the borders ; the lower with 

 a short, the u]iper with a long rough hair-point : capsule small, 

 emergent upon an arcuate pedicel, inclined or pendent, oval, 

 smooth, thin, yellowish brown ; lid convex at base, obtusely
