Dioicous ; robust, in broad lax incoherent tufts, black at base, 

 fuscous-green above, canescent ; stems dichotomous i 3 in. high, naked 

 at base, sparingly branched. Leaves subequal, erecto-appressed, when 

 moist strongly recurved, then erecto-patent, very long, from an erect 

 oblong carinafce-concave plicate base, with revolute margins, longly 

 lanceolate, subcomplicate-carinate, prolonged into a smoothish hair ; 

 cells at base i-stratose, linear rectangular, dilated towards margin, 

 upper rounded-quadrate, 2 4-stratose at apex, more or less papillose, 

 all slightly sinuose ; nerve strong, canaliculate, rounded at back. Perich. 

 bracts larger, erect, laxly areolate. Caps, on a short pale arcuate seta, 

 ovate, lo-striate, when dry oblong and deeply sulcate, pale brown, 

 leptodermous; cal. 5-lobed, annulus of 3 rows of cells, lid rostellate, 

 straight or subacicular ; teeth broadly subulate, purple, densely articu- 

 lated, irregularly cleft and perforated. Male plant more branched, infl. 

 terminal, bracts ovate, shortly acuminate. 



HAB. Quartzose rocks in mountains ; very rare. Fr. 34. 

 Clova mountains (Fergtisson 1868 ster.) ! ! 



Resembles G. decipiens, but is more robust and of a more obscure tint 

 the leaves longer with nearly smooth hairs, the nerve channelled above, 

 5-stratose. From G. trichophylla it differs by the robust habit, upper cells 

 more opake and bistratose, lower longer and narrower. The branches in 

 G. elatior are generally more or less incurved.

Autoicous; in small green cushions. Leaves elongato-lanc., 

 gradually attenuated into a longish hair, the margins plane. Caps, 

 erect, subexserted, oval-oblong, smooth; lid conical, obtuse, annulus 

 small, teeth nearly entire or perforated. (T. XLIX, D.)
