158 SYNOPSIS OF THE FLORA OF COLORADO. 



striata sicca plicato-striata, apophysata ; peristomio nullo ; calyptra 

 longiori fusca, apice rugosa. 



This form is referable, by its leaves and the ribbed capsule, to E. rhab- 

 docarpa: by the absence of peristome to E. vulgar-is, and by the apoph- 

 ysate capsule to E. apophysata, IS. & H. It is apparently a new spe- 

 cies. The specimens, however, are too few and incomplete for a satis- 

 factory diagnosis.
