short spike of fructification, — This curious little genus is the 

 link uniting Lynopodmm with OpMoglossimif having the pedun- 

 culate spike of O, Sergicmvm, with the fructification of a 

 lAfcopodmm,

Spore-cases (antheridia) one-celled, two-valved, opening by a 

 transverse vertical cleft, renifonn; sessile and solitary in the axils 

 of the leaves, or of bracts collected into spikes of fructification. 

 Spores numerous minute, globosely-tetrahedral. 



Moss-like terrestrial or epiphytal plants, with leafy stems, 

 simple or branched, erect or pendulous ; the leaves nearly uni- 

 form, and disposed in from eight to sixteen, rarely in about four 

 rowsj on the stems ; the fructification sometimes occupying the 

 axils of the upper leaves, sometimes those of bracts coEected into 

 terminal or lateral sessile or pedunculate cone-like cylindrical 

 spikes. — This genus differs from SelagineUa, in having but one 

 kind of sporO'case, that called an ontheridiMm; it also differs 

 in having the leaves nearly uniform, and usually disposed in many 

 rows equally around the stem.
