latioribus, theca in pedunculo gracili rubro horizontal pendulave cla-

Intermediate in size between B. alpinum, Linn., and B. Sauteri, 

 B. et S., but most nearly allied to the former, from which it is 

 distinguished by its smaller size, short densely tufted stems, and 

 the form and substance of the leaves. In all the specimens yet 

 examined there has been no trace of internal peristome. 



B. obovatum, sp. nov. Dioicum, foliis patentibus obovatis rigidis nervo 

 crasso breviter excurrente mucronatis, margine crasso tereti superne 

 parce indistincte denticulato, cellulis fere omnibus conformibus utriculo 

 repletis basi nee oblongis nee rectangularibus, theca in pedunculo 

 elongato clavato-cylindracea pendula, operculo conico, peristomio nor- 

 mali. 

 Hab. Madeira, near Funchal, on the earth, 1858, Johnson. 

 Like B. Donianum, Grev., in size and habit, but with leaves 

 twice as wide, having a firm terete margin, and cells much smaller ; 

 in the same particulars it differs from B. capillar e, Hedw., which 

 is also found in Madeira.

 foliis quadrifariis compressis planis, seriebus dorsalibus divergentibus

Hab. Madeira, Joao Gomez Ravine, about springs, Johnson. 



The specimens of this fine moss are too fragmentary to give a 

 good idea of its habit ; it appears to be prostrate, but not rooting. 

 Some of the specimens are more than 2 inches long, and produce 

 irregular branches resembling the main stem ; others have nume- 

 rous short branches with uniform small oval obtuse leaves, still 

 retaining, however, the quadrifarious arrangement ; but in both 

 cases the branches are confined to one side of the stem. The 

 leaves are pale glaucous green, and so inserted as to leave the stem 

 continuously visible along the dorsal side ; the arrangement in
