450 ON THE NEW SPECIES OF MUSCI. 



Barbala irnsqualifolia. — Foliis ovato-lanceolatis obtusis 

 margine revolutis, peristomii dentibus bis contortis.— (Tab. 

 XV. D). 



Barbula replicata. — Foliis lanceolato-subulatis obtusiuscu- 

 lis brevissime mucronulatis siccitate contortis. — (Tab. XV. 

 C.) — Leaves narrower and longer than in the last. 



Barbula rectifolia, is Barbula gracilis (Schwaegr.), var. seta 

 longiori. 



Barbula erythrodonta, foliis lanceolatis acuminatis carinatis 

 raarginatis. — (Tab. XV. F.) — A very remarkable Moss, with 

 much of the habit of Leptotheca speciosa (Hook, et Wils.) — 

 The teeth of the peristome united below into a short tube. 



Barbula torquata, allied to Tortula unguiculata, but the 

 leaves more acute. When dry it resembles B. replicata, to 

 which it is also allied. 



Barbula crassinervia, is Tortula recurvata, Hook. Muse. 

 Exot. t. 130, var. seta breviori. — A specimen from the Cape, 

 (Mund, n. 30), is still smaller, and intermediate between this 

 and T. parvula (Hook, et Grev.), which does not appear to 

 be a distinct species. All these have certainly the peristome 

 of Tortula, but are probably only a more developed state of 

 Desmatodon nervosus, (Br. et Sch.) — The leaves and inflo- 

 rescence are exactly the same. 



Barbula rufiseta, is Tortula Australasia, (Hook, et Grev.), 

 which may be only a state of Tortula vinealis, (Bridel).— I n 

 this Moss the peristome is very slightly twisted, and ap- 

 proaches very closely to Trichostomum in its structure. 



Bryum pungens, B. inmquale, and B. multicaule. — These 

 three are most closely allied, the two latter especially seem to 

 belong to the same species. In B. pungens the leaves are more 

 acuminated and less crowded, but no essential difference is 

 perceptible. The nerve of the leaf in all three ceases below 

 the apex. 



Bryum tenuissimum, is Scbistidium pulchellum (Hook, et 

 Wils.), but not a Schistidium as now denned by Bruch and 

 Schimper. For this and the allied species, S. arcuatum, the 

 new generic name, Eccremidium, is proposed for a genus cha-
