H. scabriseta, Hook. Musc. Exot. t. 52, has the seta 
decidedly hispid, and may be truly distinct from H. Merkelit; 
but it is doubtful whether the latter moss, and H. micro- 
carpa, of Fl. Bras. are really different from H. depressa.

87. H. marginata, nov. sp. Caule fastigiatim ramoso, ramis 
brevibus subcompressis, foliis laxiusculis subpatentibus

nuissime binervibus, nervis supra medium desinentibus, 
capsula ovata cernua, operculo rostrato, calyptra carnosa

Except in the distinctly margined leaves, this moss bears 
a strong resemblance to H. Olfersianum, Fl. Bras, t. 3, f. 4.
