SECT. IV. ANTHOCERATEiE. 



Capsula (primaria) e substantia frondis exserta, nunquam 

 styligera ! 



General remarks on Anthoceros. 



Radiately frondose, estomatous. 



Essential points of Anthoceratious structure. 



Decided male flowers, of the ordinary acrogenous structure 

 with most evident dehiscence, enclosed in common apartments 

 in the frond. 



Female flower pre-existing, none,- but consequent on impreg- 

 nation ; the process of which consists in the application of 

 the fertilising matter to the upper surface of the frond, into 

 which it penetrates, causing the origin at particular or pro- 

 miscuous? spots of the young capsules, to carry in their 

 growth upwards up a calyptroid process formed from the sub- 

 stance of the frond. 



Capsules spirally 1-2, valvular with columella. 



ANTHOCEROS. 



Capsula sursum bivalvis, columella centrali libera instructa. 



Plantulae monoicae. Frondes varie lobatae. Antherae in 

 cavitatibus, frondis sursum ore lacero hiantibus contentae, 

 aggregatae, centrales evolutiones ; cellulis pulchre reticulatim 

 areolatse, apice dehiscentes. 



Capsulae sessiles, basin frondi immersae, involucro e frondis 

 substantia primo clauso demum apice lacero inferne cinctae, 

 subsemibivalves initio missa cellulosa (calyptra auctoribus 

 quibusdam pessime dicta) terminates. Sporula processibus 

 cellulosis immixta, convexo-trigona.
