83. LEPTOBRYUM, Schimp. 

 Plants slender, radiculose at base. Leaves narrow, flexuous, 

 subulate, glossy; areolation (as in Webera) linear-rhomboidal 

 above, the lower looser, rectangular-hexagonal. Flowers bisex- 

 ual. Calyptra very small. Capsule inclined or pendent. Lid 

 mamillate. Peristome double ; articulations of the intermediate 

 cilia appendiculate. Sj^orangium smaller than in Brywn. 



1. L. pyriforme, Schimp. Plants loosely cespitose, soft, 

 green, glossy; stem short: lower leaves distant, narrowly 

 lanceolate, the upper tufted, much longer, lanceolate-subulate, 

 more or less serrate toward the apex ; basilar areolation some- 

 what broader than the upper ; costa excurrent : capsule oval- 

 globose, long-necked, yellowish brown, glossy; pedicel long and 

 slender ; lid apiculate from a conical base ; annulus large, —

Stems slender. Leaves lanceolate, glossy; areolation rhom- 



boidal-hexagonal, narrow, more or less linear. 



The areolation of the glossy leaves and a more slender costa are the 

 essential characters separating this genus from Bryum.
