Family BARTRAMIACEAE 



A FAMILY containing only a few genera, two of which 

 are common in most localities. A third occurs only in 

 limestone regions. 



32. PLAGIOPUS Brid. (Pla-gi-o-pus) 



A genus containing only three species. Name de- 

 rived from the Greek for " oblique " and *' stalk," 

 referring to the way the seta joins the capsule. 



Plagiopus Oederi (Gunn.) Limpr. {Bartramia Oederi 

 (Gunn.) Schwaegr.) is found in mountainous and hilly 

 woods of limestone regions growing on rocks 

 or soil; not common; fruit not common. 



In order to recognize Plagiopus without the 

 use of a compound microscope, the student 

 needs to be familiar with Bartramia pomi- 

 formis, the following species, as the plants ^!^Jj^^"^ 

 are best described by comparison. 



The general characters of stems, leaves, and capsule 

 are similar to those of Bartramia pomiformis, but the 

 stems are more slender, usually 1-2 inches long, the 

 leaves shorter and less crowded, and the capsule smaller. 



Range, Canada and the northern United States, south in 

 the East to North Carolina; Europe; Asia.
