208 Dr. T. Taylor on two new species of British Musci. 



XXXIV. — On two new species of British Musci. By Thomas 

 Taylor, M.D., Dunkerron, Kenmare. Communicated 

 by William Gourlie, Jun.* 



Trichostomum saxatile, MSS. 



Specific character. — Caule subramoso, abbreviate, erecto, conferto ; 



foliis ovato-laixceolatis, concavis, margine reflexis, integerrimis, 



epiliferis, apice obtusiusculis, nervo sub summo apice evanescente; 



peristomii dentibus brevibus, laciniis alternatim angustioribus, 



operculo suberecto, calyptra hinc fissa. 

 Hab. In locis montosis, saxa majora coronans. Comitatus Kerriensis, 



Hibernise. 



Caules I — I unciales, aggregati, innovationibus binis. Folia flavo- 

 virescentia, anni prseteriti fuscescentia, nunquam, uti multis conge- 

 neribus solenne, in acumen elongatum producta. Capsula oblonga 

 aut obovata. Peristomium breve, trabeculis dentium lacinias vix 

 jungentibus. Operculi rostrum inclinatum. Calyptra fissura unica 

 cseteris altior ; unde genus vix firmum. 



This plant, in the ' Flora Hibernica,' has been referred to a 

 variety of Trichostomum fasciculare, Schrader, growing on 

 stones at Carig Mountain. Subsequent careful examination 

 of better specimens shows it to be very distinct in the want 

 of fascicled branches, but especially by the short peristome, 

 whose teeth are united at their bases by a pale membrane 

 rising above the mouth of the capsule. The inclined rostrum 

 of the lid and nearly dimidiate calyptra are unusual in the 

 genus. 



BrYUM RECURVIFOLIUM, MSS. 



Spec. char. — Caule erecto, subsimplici, subflexuoso ; foliis oblongo- 



ovatis, acutis, laxis, ex amplexante basi recurvantibus, margini- 



bus flexuosis, minutissime serrulatis. 

 Apud montem Knockavohila, prope Dunkerron in Comitatu Kerri- 



ensi, Hibernise. Anno 1842. 



Habitus Dicrani squarrosi, Schrader, 2 — 4 uncialis, inter Hypna 

 aliosve muscos adscendens, vix csespitosa, luteo-viridis. Caules 

 saepius duos surculos annotinos erigentes, atque ex eodem puncto 

 radices setaceas, purpureo-nigricantes paucas demittentes. Folia 

 canaliculata, subdistantia squarrosa, caulis apicem versus conferta 

 atque majora, dense cellulosa, nervo valido pallidiori in cuspidem 

 brevem excurrente ; marginibus pallidis minutissime celluloso-ser- 

 rulatis. 



Although the fructification is not known, yet there can be 

 little hesitation in referi'ing this remarkable species to the 

 genus Bryum. With the habit of Dicranum squarrosum, 

 Schrad., it has the structure of Bryum cuspidatum, Schreber. 

 A very small quantity, and only in one spot, has hitherto 

 been found.
