Han. Tasmania, Lawrence. 
From O. leptocarpum, B. and S., this species differs in the firmer plicate capsule and acute leaves; from O. Tas- 
manicum and O. speciosum, Nees, in the very much wider leaves, not patent or divergent from a suberect base, 
having elongated narrow cells, but uniform in their direction throughout their length, and composed of cells every- 
where minute and round. The cilia, like those of O. Tasmanicum, agree in substance, size, and colour with the 
teeth of the external peristome. The calyptra has not been seen. Mitten, l.c.—Prarg CLXXII. Fig. 5; 1, leaf; 
2, theca; 3, peristome : —all magnified.
