MONMOUTHSHIKE CRYPTOGAMS. 

 By the Rev. H. P. Reader, B.A. 



The following notes on the Cryptogamic Flora of the neigh- 

 hourhood of Usk, Monmouthshire (species of universal distrihution 

 being omitted), were made during a short visit there towards the 

 end of January last. Amongst Mosses I observed : — 



Phascum nitidiun, Hedw. — On moist earth, sparingly. 



P. subulatwn, L. — Frequent on dry banks. 



Weissia cirrhata, Hedw. — Not plentiful. 



Tortilla rigida, Schultz. — On wall tops, sparingly. 



T.faUax, Hedw. — In one locality, abundant. 



Cinclidotusfontinaloides, P. Beauv. — On stones, often submerged, 

 in the river Usk. 



Schistidium apocarjnun, Br. & Schimp., var. riviilare. — In 

 similar situations with the preceding. 



Pogoiiatum nanum, Brid. — On shady banks. 



Polytrichiun jiiniperinum , Hedw. — On wall tops. 



Aidacomnion palustre, Schw. — Plentiful in a swamp near Clytha. 



Milium cuspidatum, Hedw. — Shady banks. 



M. jnmctatum, Hedw. — Wet places near Clytha (in fruit). 



Fissidens bruoides, Hedw. — Abundant at the roots of trees. 



Anomodon viticulosus, Hook. & Tayl. — On walls. 



Hypniim vehuimun, Dill. — One of the commonest Hypna. 



H. striatum, Hedw. — Fine fruiting specimens in woods by the 

 Usk. 



H. speciosum, Brid. — On wet rocks at Clytha. 



H. alopecurum, Dill. — Large and abundant, but no fertile plants 

 observed. 



H. cordifolium, Swartz. — In a swamp with Aidacomnion. 



Amongst Jungermanniacem, none were more plentiful than J. 

 asplenioides, Hook. — very fine and characteristic of the Flora. I 

 saw no traces of fruit, which, indeed, I have only found (and that 

 very rarely) in woods on the Cotteswolds. 



J. platijphijUa, Hook. — The dark green layers formed by this 

 species are most remarkable on the walls of Raglan Castle. 



The Piicciacece were represented by Pi. t/lauca and R. fluitans. 

 The former I met with abundantly in turnip -fields on heavy soil, 

 also on hedge-banks : the latter on the surface of a pool near 

 Clytha. 



liamaiina fariiiacea, L. — This common lichen, which rarely 

 occurs in fruit, I found in that condition at Raglan. 



Lecidea rubella, Ehrli. — On old elms, not infrequent. 



Graphis scripta, Ach., and G. elegans, Sm. — I collected very 

 handsome forms of these two species.
