This is Dr. Best's determination of the moss issued as nos. 

 55 and 55a of my N. Am. Musci Pleurocarpi, confirmed by J. 

 Cardot and Dr. E. Levier. It is monoicous, hence is not P. syl- 

 vaticum. It is too strongly differentiated from P. denticulatum to 

 be with propriety included under that species, although I was at 

 one time inclined to place it under forma propagulifera Ruthe, 

 because of the numerous protonema-like propagula borne on the 

 base of the midribs of the leaves. A very striking character of 

 this plant is the folding together of the leaf at the base to sheathe 

 the leaf next above. 



Plagiothecium striatellum (Brid.) Lindb. Common in swamps, 

 but having spreading leaves like a Campylium, 



Raphidostegium admistum (Sulliv.). Hypnum admistum
