HAB. Trees and rocks in mountainous countries. 



Sir James Smith, on the authority of Dillenius, has at*j 

 tributed to H. atro-virens a subulate lid : but the plant re- 

 ferred to in the Hist. Muse. t. 43. f. 67? is a very distinct 

 species from Virginia (not Patagonia, as mentioned by mis- 

 take in Engl. Botany). H.Jttamenlosum of Dickson dif- 

 fers in no particular from our plant, nor does the H. atte- 

 nuatum of the same author, as we have ascertained by an 

 examination of his own specimen in Mr. Turner's Herba- 

 rium. Equally authentic specimens, viz. from the younger 

 Hedwig, prove our plant to be the same as his Leskea in- 

 curvata, but we have preferred the older name given by our 

 countryman. We have been greatly inclined to add to our 

 synonyms H.Jkwiatile^ which accords so well in its foliage; 

 but that has more distantly placed leaves, and a longer cap- 

 sule. Our plant likewise bears no inconsiderable resem- 

 blance in many points to H.JHicinum ; it differs however 

 in being procumbent, in its loose and straggling ramifica- 

 tion^ more closely set, shorter, broader, more concave and 

 more obtuse leaves, with the margin more reflexed, quite 

 entire, the nerve broader, of the same colour as the leaf, 

 disappearing below the point : besides all which the texture 

 of the leaves is thicker and softer, with distinct cellules; 

 whereas in H.Jilicinum they are somewhat scariose. 



51. H. palustre*, leaves secund, ovate, somewhat acuminate, 

 concave, entire, margins incurved above ; nerve short, often 

 forked, sometimes obsolete ; capsule oblongo-ovate, cernu- 

 ous ; lid conical. (TAB. XXVI.)

HAB. Banks of rivers and standing waters, and on wet 

 rocks, abundant. 



Variable as is this species, we trust it will be found con- 

 stant to the above characters. The plant, or at least the 

 main stems, is usually upright, thickly crowded j the leaves 

 flaccid, varying from a deep lurid green, the most common
