132 HANDBOOK OF BRITISH MOSSES. 



faintly two-nerved ; cells very narrow ; fruitstalk smooth ; spo- 

 rangium elliptic,, sometimes cernuous, more frequently pendu- 

 lous as in Bryum ; lid conical, with a short beak or apiculus. 



Distinguished at once from H. denticulatum by its glossy 

 foliage, much narrower cells, rostrate beak, etc., and indeed 

 having more the habit of some forms of H. cupressiforme. 

 Received originally from Nootka. I do not find any notice of 

 it in Schimper's ' Synopsis/ 



85. H. undulatum, L. ; dioicous; stem prostrate, prolife- 

 rous, branches mostly simple, complanate ; leaves imbricated, 

 ovato-oblong, apiculate, undulated transversely, with two short 

 nerves at the base ; sporangium cylindrical, cernuous, striated 

 when dry; lid shortly rostrate. Hook, fy Wils. t. xxiv. ; Eng. 

 Bot. t. 1181. ; (Plate 12, fig. 4) ; Moug. 8f Nest. n. 45. 



In woods and dry heathy places, especially in subalpine dis- 

 tricts. Bearing fruit in spring and summer. 



Forming whitish-green irregular tufts of various lengths, 

 often amongst other Mosses. Stem slightly divided, sending 

 out innovations clothed with small leaves ; branches mostly 

 simple, complanate, leaves ovato-oblong, attenuated upwards 

 but not acuminate, entire, faintly two-nerved at the base; 

 cells narrow, broader at the base; fruitstalk 2 inches long; 

 sporangium cylindrical, curved, striate when dry, cernuous ; 

 lid with a short beak. 



One of the finest of our Mosses, and most distinct. Hyp- 

 num micanSjWils., characterized by its dioicous inflorescence, 

 prostrate, slender, filiform, sparingly branched stems, spread- 

 ing, shining, subsecund, roundish, apiculate, concave, serru- 

 late, obscurely two-nerved leaves, is of very doubtful affinity 

 in consequence of the female fruit being unknown. The 

 patches are of a pale yellowish-green ; the cells about as large 

 as in H. denticulatum, with the exception of those at the angles,
