112 HANDBOOK OF BRITISH MOSSES. 



rated with two or occasionally three nerves, often more or less 

 combined, and reaching halfway up ; cells narrow; perichsetial 

 leaves large, serrate, their tips spreading ; fruitstalk even, 

 twisted when dry ; sporangium ovate, turgid, cernuous ; lid 

 conical, with an acute apex. 



Allied to the last, but distinguished by the conical lid, pli- 

 cate leaves, and less regular and frequent divisions. 



56. H. Oakesii, Sull. ; stem arched, distantly pinnato- 

 ramulose, clothed with branched, down-like paraphylla; leaves 

 subelliptic or ovato-oblong, concave, slightly plicate, with the 

 margin strongly reflexed, apiculate ; more or less serrate 

 above ; furnished with two nerves at the base, which are often 

 more or less combined ; fruitstalk even ; sporangium ovate, cer- 

 nuous; lid conical, with a short beak. Hook, fy IVils. t. Ivii. 



Found at present only on Hen Lawers. Bearing fruit in 

 autumn and early spring. 



Dioicous; forming green tufts. Stem red, with frequent 

 arched innovations, which are distantly pinnate, clothed with 

 repeatedly-branched down-like paraphylla ; leaves moderately 

 crowded, concave, roundish-elliptic, with an abrupt apex, or 

 ovate and more acuminate, more or less striate, minutely ser- 

 rate above; perichsetial leaves squarrose ; fruitstalk 1 inch 

 long, even ; sporangium short, ovate, cernuous ; lid conical, 

 with a short, straight, or curved beak. 



Of a brighter green than the last, and less divided ; the 

 margin of the leaves much reflected, and the lid longer. The 

 degree in which the leaves are serrated seems to vary much. 

 Schimper says they are more deeply serrated than in the last ; 

 Wilson figures them as coarsely serrated, though not so 

 strongly ; while in authentic specimens from Sommerfelt, I 

 find the serratures minute. The paraphylla are far more 

 deeply and intricately divided.
