155. Trichostomnm fiewicaule, B.».ndS. (Didymodon, 5nc?.) Abun- 

 dant, both on the limestone and basalt. This is a moss which I had 

 concluded from previous observation to be confined exclusively to

 T.y Near streams.

158. — fasciculare, Schrad. Frequent on rocks and stones. 



159. — heterostichum, Hedw. Rocks and walls. 



160. — lanuginosum, Hedw. Abundant. Among the mountains 

 the rocks and stones are frequently quite hoary with this moss.

162. Weissia acuta, Hedw. Plentiful on basaltic rocks by the 

 Tees at Winch Bridge and other places.

3. — asplenioides, L. Frequent in the low grounds ; scarcely 

 ascending to the subalpine regions. 



4. — Bantriensis, Hook. MSS. Caule erecto vel adseendente, 

 subramoso ; foliis ovato-rotundatis, obtuse emarginatis, peri- 

 chsetialibus conformibus ; stipulis parvulis, lanceolato-subulatis, 

 integerrimis, basi 1-2 dentatis, bifidis, vel laciniatis ; fructu ter- 

 minali, calycibus subcylindricis, ore angustiori tubulato ciliato.

 Synops. p. 16. Suppl. tab. 3. 



On sandy deposits by the Tees and its tributary streams ; in the 



* I should have scrupled to retain Hooker's specific name, had it not 

 been already published by Llndenberg and Nees in the * Species Hepathi- 

 carum ' (as I am informed by Dr. Taylor) ; although these authors appear 

 to have been unacquainted with the plant, and to have presumed on its 

 being distinct merely from Hooker's brief account of it.
