In fructiferous young plants only the spreading outer halfs of the 

 fertile fronds are soriferous, with the horns (which are normally simple 

 in the adult plants) not rarely elongated and slightly dichotomously 

 compound; the pendulous inner halfs then are sterile, with the sinus 

 between the primary fork-branches whether, or not provided with a more 

 or less produced central lobe which may grow out to a branch resembling 

 the lateral primary branches, so that the pendulous inner halfs become 

 apparently trichotomous.
