106 HYPNUM. 



The character here given will show how closely this spe- 

 cies is allied to the preceding; and indeed, except in the! 

 smaller size and the somewhat narrower leaves, and theirs 

 more upright direction, we ean find no mark of distinction J 

 So also in the H. intricaium of authors, the specimens that! 

 x we have seen are smaller than in our H. velulinum, and the! 

 leaves less broad. Hedwig mentions a difference in the an-J 

 nulus, which we have, not been able to verify. 



39. H. ruscifolium ; stems variously branched, leaves loosely! 

 imbricated, subpatent, broadly ovate, acute, serrated, con-I 

 cave, their nerve reaching nearly to the summit \ capsule! 

 ovate, cernuous; lid rostrate. (TAB. XXVI.)

HAB. Upon wood and stones in pools and rivers. 



The stems often exceed a span in length, and the leaves! 

 in certain situations attain a greater size than in any BriJ 

 tish species of Hypnum. 



40. H. striatum ; stems variously branched ; leaves patent, cor J 

 dato-acuminate, serrated, striated ; nerve reaching beyoncH 

 the middle ; capsule oblongo-ovate, cernuous ; fruitstalkl 

 smooth; lid rostrate. (TAB. XXVJ.)

This species comes near in habit to H. rutalulum ; but! 

 is a larger and more robust plant, with leaves more patent ;| 

 broader and more decidedly striated, with a shorter point! 

 and longer nerve ; the fruitstalks are smooth, and the lidl 

 rostrate, 



41. H. confertum; stems variously branched; leaves erectoj 

 patent, ovate, acuminated, concave, serrated, their nerve! 

 reaching half way ; capsule ovate, cernuous ; fruitstalkl 

 smooth; lid rostrate. (TAB. XXVI.)

HAB. Trunks of trees, old rails, and on banks. 



We have compared this with the Pennsylvanian H. ser-\ 

 ridatum of Hedwig, and cannot find even the slight diffe-i 

 rences which Mohr has noticed. A small variety^ growing; 

 on trees, has the leaves occasionally subsecuncU
