" Musci AUeghanienses," no. 229, as " Sphagnoecetis commwiii, var. 

 2," growing on decayed logs; 0. Sphagyii, no. 228, as " S. communis, 

 var. 1 " — a dense luxuriant patch, on Sphagnum. 



I did not once gather 0. Sphagni verum in the Pyrenees, nor yet 

 in the Andes ; but 1 have si'en specimens from the Landes, near Dax, 

 and (as we have seen) it abounds in the great plain lying eastward of 

 the Andes ; whereas 0. denudatum is frequent in the lower Pyrenees, 

 and grows also in the Andes, at a moderate elevation ; all whicli seems 

 to show that 0. Spka/jni is a plant of the plains, and 0. denudatum of 

 the hills. Further evidence is needed to determine the range in alti- 

 tude of both species, in the temperate as well as in the torrid zone. I 

 cannot make out the existence of either farther south than lat. 6.\°, 

 viz., on Mount Campana. Both species are common in England, but 

 require more accurate discrimination before the localities can be quoted 

 with confidence. The range in climate of 0. Sphagni is obviously 

 very great, but not unlimited ; for it is quite as much at homo on the 

 equator, with a temperature ranging from 70" to 90° Fahr., as it is 

 herein lat 54" N., where the thermometer sometimes falls to zero, 

 a^ on Jan. 1, 1875 ; but becomes much scarcer beyond the parallel of 

 60" N.
