GRIMMIEI. 



Allied to the last, but with a short hair-point, and denser 

 sinuated reticulations at the base. 



9. G. torta, Hornsch.; densely pulvinate, soft, flexible; 

 leaves crecto-patent, spirally curved round the stem when dry, 

 lanceolate, keeled, acuminate, the lower pointless, the upper 

 very shortly hair-pointed. Hook, fy Wil*. t. xxxii.; Grev. Sc. 

 Crypt. Fl. t. 199. 



On alpine rocks. Always barren, both in this country and 

 on the Continent. 



Forming dense tufts, bright-green above, 1-2 inches high, 

 dark below, the individual plants easily separating from each 

 other. Leaves three-ranked, channelled above along the 

 nerve, sometimes but not always hair-pointed ; margin 

 slightly reflexed ; leaf-cells larger at the angles, on the disk 

 narrow, subquadrate or punctiform upwards. The arrange- 

 ment of the leaves when dry calls to mind Hypnum trifa- 

 rttfm, 



10. G. spiralis, Hook, fy Tayl. ; dioicous; pulvinate ; stems 

 slender ; leaves lanceolate, hair-pointed, erecto-patent, spirally 

 imbricated \vhcn dry ; fruitstalk curved ; sporangium small, 

 ovate, nearly even ; lid short, obtuse ; ring broad. Hook. 

 fy mis. t. xxxii. ; Grev. Sc. Crypt. Fl. t. 203. 



On exposed alpine rocks. Ireland, Scotland, and England. 

 Bearing fruit in autumn. 



Forming large dense cushions. Stems easily separating as 

 in the last species; margin of leaves recurved; sporangium 

 with eight obscure furrows or quite even ; veil lobed at the 

 base ; teeth bifid, recurved when dry ; leaf-cells as in the last, 

 except that those at the angles are very large. 



11. G. orbicularis, Br. 8f Schimp. ; monoicous; densely
