at the apex of the stems ; stem leaves short, 3-5 mm. long, 

 slightly falcate at the tips of the branches, tubular with incurved, 

 entire margms ; vein more than one-third of the width of the base 

 of leaf excurrent with a few teeth at apex ; basal cells thin, hyaline 

 to the vein, not colored. 



Plants sterile and much less rigid than is usual in this genus ; 

 their alliance was not indicated nor determined. 



Cauipylopus sp. undetermined. Yungas, 6000 ft. (31 16). 



Plants fragmentary and broken. Stems 2-3 cm. high, prolifer- 

 ous with fasciculate branches at apex, branches often 15 mm. long 

 with the leaves crowded at the summit ; leaves curled and twisted 

 when dry, 3-5 mm. long, blade narrow, forming a serrate border 

 of one row of cells almost to the apex ; vein papillose on the back ; 

 cells enlarged at base, brown at angles; leaves of the branches 

 shorter, often entire, and radiculose at base, perichetial leaves very 

 long pointed, costate, entire, or scarcely serrulate ; cells much en- 

 larged at base, brown, upper oblong ; antheridia in heads matted 

 with brown radicles; pedicels several in the same head, 8-10 mm. 

 long, curved, becoming erect where dry; capsules 1.5 mm. long, 

 ovoid, not ribbed when dry ; peristome red, lid not seen. 



These specimens are closely allied to C. annotiniis Mitt., and 

 C. dracJiypJiylhis Mitt., and C. niulticapsularis Sch., from all of 

 which they differ in the leaves and the smooth walls of the cap- 

 sules when dry. 



Grimmia nano-globosa C. M. n. sp. Mapiri, 5000 ft. (3195). 



Plants pulvinate in gray cushions, stems 5-8 mm. high ; leaves 

 crowded with a long, rough, white hair-point, blade carinate, cells 

 small, almost quadrate, sinuous, basal ones elongated. Dioe- 

 cious (?). Perichetial leaves with a long sheathing base, the white 

 tip reaching the lid of the capsule. Pedicel erect, straight, 3-4 mm. 

 long; calyptra lobate-mitrate, capsules 1-1.5 mm. long, lid with a 

 straight beak, .5 mm. long; annulus narrow, of several single 

 rows of cells falling in fragments with the lid; peristome red; 

 teeth short, papillose; spores smooth, .ooB-.Oio mm. 



A smaller species than either G. ovata Web. & M., or G. longi- 

 rostris Hook. 



Compared at Kew with Matthews' Peruvian specimens labelled 

 G. ovata and illustrated by W. Wilson. The Bolivian specimens 

 are smaller.
