This is indeed a variable moss, as one of its names implies, and no 

 doubt the last species has often been confounded with it. The excurrent 

 nerve varies in the length of the point, but there is always a certain tapering 

 upward of the lamina, this, with the minute opake areolation and plane 

 margins, best distinguish it. Mr. Mitten distributed specimens of the 

 Var. (3. as Barbula paludosa SCHWAEGR. (i8n) = Tortula crocea BRID. (1806), but 

 it does not belong to that species, for although having much external resem- 

 blance to it, it may be noted that Barbula crocea has shorter, straighter and 

 more erect leaves, suddenly pointed, the nerve only forming a short apiculus, 

 the areolation of the upper part is also smaller and more indistinct, and the 

 margin towards the apex has several irregular teeth. 



17. MOLLIA LUTESCENS Lindb. 



Dioicous ; resembling M. brachydontia, but with longer ligulate 

 leaves, aristate with the terete excurrent nerve, the cells all pellucid 

 and pulvinate. (T. XXXVIII, C.) 



SYN. Mollia lutescens LINDB. MSS. 



Dioicous ; in small lax incoherent tufts, yellowish green above, 

 rufescent below. Leaves accrescent upward, erecto-patent when moist, 

 crispate when dry, very long, narrow and ligulate, scarcely concave, 

 suddenly pointed and aristate with the excurrent nerve ; basal cells 

 narrowly rectangular, pellucid, upper all pellucid, very distinct and 

 with chlorophyl, not papillose, but pulvinate in outline.
