flexed on the borders in the upper part, obtusely pointed, soft,

 oblong or subcylindrical, reddish at the orjfice ; lid subulate- 

 rostrate ; teeth linear-lanceolate, entire at the minutely jjunc-

 longer and narrower capsule, the compound annulus, the entire teeth, etc. 



15. OREO WEISIA, Schimp. 

 Plants pulvinate. Leaves soft, coarsely papillose and minutely 

 serrulate above ; basilar areolation hyaline, the upjjer chloro- 

 phyllose. Perichaetiuin not sheathing. Capsule more or less 

 curved. Inflorescence and jDeristome of Dicrmioweisia. 



1. O. serrulata, Schimp. Densely pulvinate-cespitose ; 

 plants radiculose below : leaves crowded, narrowly lanceolate, 

 enlarged and concave to the middle, the perichaetial longer, all 

 flexuous, open or incurved, carinate above, costate to below the 

 somewhat obtuse apex : capsule of thick texture, oblong, short- 

 necked ; pedicel whitish ; lid with a short blunt inclined beak ;

16. RHABDO WEISIA, Bruch & Schimp. (PI. 1.) 

 Plants small, dichotomous, densely aggregate. Leaves long, 



narrow, crispate when diy, minutely papillose on both faces ; 



areolation quadrate, chlorophyllose in the upper part, longer, 



hexagonal and hyaline near the base. Inflorescence monoecious. 



Capsule 8-striate, 8-costate when dry. Lid long-subulate, beaked. 



Teeth of the peristome linear-subulate, enlarged at base.
