Plagiobryum Zierii (Dicks.) Lindb. Forty-mile Cr., 

 mixed with Br yum arcticum. Near Head of Macdonald 

 Lake, Aug. 7. The neck of the capsule is often not longer 

 than sporangium. It is a larger species than demissum with 

 costa of perichaetial leaves mostly entering point but usually 

 hardly excurrent. P. demissum has a stout, red costa dis- 

 tinctly excurrent in the upper leaves (317). 



Pohlia longicolla alpina (H & H.) Hueben. Neihart, 

 Belt Mts., on rocks, 5,000 ft., Sept. This variety has a 

 shorter neck to the capsule than the type. The species is 

 credited to the Cascade Mts., collected by Lyall. I have 

 seen no other records and no American specimens except 

 these from Neihart. The plant is a glossy species somewhat 

 like cruda but may be distinguished from that by the erect, 

 not spreading or reflexed leaves, which are more lanceolate 

 in outline, with much shorter basal cells, those in the angles 

 being very short rectangular to almost square. From nutans 

 it may be known by the less perfect peristone, thinner walls 

 of leaf-cells and by the single row of nearly square, not 

 transversely elongated cells about mouth of capsule with 

 margin of irregular outline (186).
