The genera present a wonderful variety in the reproductive organs, but in almost 

 all the existence of pistillids and antherids has been demonstrated, and in most 

 m the development of the spore-cases from the so-called pistillids has been traced. 

 In tlm>e in which the plants most resemble Mosses (Bryacea?) in vegetation, as in 

 Jungermanriise, the pistillids are very like those of Mosses; this is also the case in 

 MiK-hantia; but in Pellia, Anthoceros, and other genera, the rudiment of the spore- 

 case bears a striking resemblance to the so-called ovules of Ferns, Rhizocarps, &c, 

 occurring upon the expanded fronds the same way as those bodies do upon the pro- 

 embryOB of the said families. In all cases the physiological stages are analogous to 

 those nf Mosses; since the pistillids produced upon the fronds or leaf-bearing stems 

 developed directly from the spores, go on to produce a spore-case alone, in which 

 the now spores are developed, without the intervention of the stage of existence pre- 

 Bented by the pro-embryo of Ferns and Horsetails (Equisetacese), where the pistillids 

 and antherids occur upon a temporary frond, and the former give origin to the 

 regular stem and leaves of the plant. — Henfrey.
