the dry as in the moist state. Perichatial leaves deeply but un- 

 equally serrated. 



This interesting moss bears so strong a resemblance to H. ser- 

 pens, that, had I not been struck by its peculiar colour and re- 

 markably neat appearance, I might have passed it over for that 

 species. The characters above stated will suffice to show those 

 who have studied H. serpens that H. confervoides is widely differ- 

 ent from it in several essential particulars. 



80. Hypnum crassinervium, Tayl., Wils. On limestone rocks by 

 the Tees, near the foot of the High Force. 



81. — cupressiforme, L. Everywhere. 



82. — curvutum, Sw. Trees and rocks. 



83. — cuspidatum, L. Common. 



84. — denticulatum, L. Frequent in moist shady situations. 



85. — filicinum, L. Common, but rarely fructifying. 



86. — fluitans, L. In Hell Cleft. 



87. — incurvatum, Schrad. On stones at the base of the High 

 Force, on the Durham side of the Tees ; growing with Orthoti'ichum 

 rupestre. I had nearly passed this over for H. serpens, which it cer- 

 tainly much resembles, especially in the form of its capsules. It is 

 also not unlike //. populeum, with which species it grew intermixed. 



88. — loreum, L. Frequent. 



89. — liitescens, Huds. Limestone rocks in Ettersgill beck and 

 Hell Cleft. 



90. — molluscum, Hedw. Frequent. 



91. — mult iflor urn, Tayl. On trees in Egglestone Wood and Bal- 

 derdale. A Hypnum, which for the present I must consider a var. 

 of this, grows in the fissures of limestone rocks in Hell Cleft, at the 

 High Force, and other places ; it is remarkable for the reddish hue 

 of its foliage, in consequence of which I at first mistook it for Leskea 

 rufescens. The leaves are longer and narrower than in the usual 

 state of H. multiflorum, and when dry are striated. 



92. — myosuroides, Hedw. Common in rocky situations. 



93. — palustre, L. Wet rocks and on stones in streams, fructi- 

 fying copiously. 



94. — plumosum, L. On rocks in and near streams. 



95. — polymorphum, Hedw. By the Tees below Winch Bridge ; 

 barren. 



96. — populeum, Hedw. Walls and rocks. 



97. — prcelongum, Linn.^l 



98. — proliferum, L. >Everywhere common. 



99. — purum, L. J 



100. — rugulosum, Web. This has been found by Mr. Ihbotson on 

 the limestone above Falcon Clints ; but as I only searched the base 

 of those rocks, I did not observe it. 



101. — ruscifoUum, Neck. Streams, frequent. 



102. — rutabulum, L. Everywhere. 



103. — Schreberi, Willd. Heaths. 



104. — scorpioides, L. Bogs.
