Pylaisia seems to be favored by most botanists in spite of 

 technical objections, so Pylaisiella is dropped in this edition.

ENTODON.* 



The Entodons have erect symmetric capsules, ecostate, very 

 concave leaves and a beautiful glossy yellow-green color that 

 enables one to recognize them without much trouble. The ma- 

 jority of the species are flattened, but have the appearance of 

 being pressed flat instead of having the leaves apparently two- 

 ranked as in Plagiothecium. 



E. SEDUCTRIX (Hedw.) C. Muell., the Round-stemmed Ento- 

 don, is probably the most common species in the southern portion 

 of our range. The stems and branches are round and julaceous 

 with closely imbricated leaves. It grows on rotten wood, soil, 

 moist rocks, bark of trees, etc. 



E. CLADORRHIZANS (Hedw.) C. Muell., the Flat-stemmed En- 

 todon, is nearly always found on decayed wood, rarely on soil 

 rich in humus. Its strongly flattened stem and branches easily 

 distinguish it from the Round-stemmed Entodon. This charac- 

 ter, together with the peculiar color characteristic of the genus, 

 will differentiate it from species belonging to other genera. 

 There are a number of other American species of Entodon that 

 resemble the Flat-stemmed Entodon, but they are rare and not 

 likely to be met with. The leaves of both species are very con- 

 cave, but those of the Flat-stemmed Entodon are larger. Both 

 species mature their capsules in autumn or early winter.
