Fructification of two kinds. Capsules, in an early stage, co- 

 vered with a calyptra, tipped with a style, which bursts trans- 

 versely and regularly and rises up with the mostly pedunculated 

 and operculated capsule. Operculum or lid deciduous in most 

 instances; month of the capsule furnished with a single or dou- 

 ble fringe ; containing seeds surrounding a columella, destitute 

 of spiral filaments : and sphserical pedicellated reticulated 

 lodies, concealed for the most part in peculiarly shaped leaves, 

 and which have been considered anthers. 



Plants of small size, of a more or less compactly cellular structure, 

 readily reviving by the application of moisture after being dry, 

 bearing leaves which are very rarely indeed divided, oftennerved, 

 entire or toothed, or serrated at the margin.
