Dioicous and pseudautoicous ; in lax spreading yellow-green glossy 

 tufts. Stem depressed, irregularly pinnate, branches erect or patent, 

 straight, pointed, lowest leaves distant, ovate at base, suddenly narrowed 

 into a recurved subula, entire, nerveless. Leaves imbricated, elongate 

 lanceolate, acuminate, 4-plicate, margin narrowly recurved in lower half 

 and faintly serrate at point, nerved for J; cells linear, about 12 times 

 long as broad, shorter and laxer in basal angles. Perichaetial bracts 

 spreading at points, innermost erose above, suddenly subulate, with a 

 weak nerve, seta purple, rough, capsule cernuous, cylindraceous, gibbous, 

 pale brown, lid conic, obliquely rostellate ; teeth orange, lineal-subulate , 

 cilia two.

Very like the next species in the form and structure of leaf, but of 

 different habit ; the plant is taller with longer and straighter branches, and 

 it has not the brilliant shining gloss of H. sevicemn.
