Mr. Brown in his admirable Prodromus Florce Novce Hollandice, mentions that this plant is liable 



great variation both 



gard to the number of pinnae, of which the fructifying appendage 



composed, and to the roughnes 



of the frond. Sir James Smith, too, mentions an Otaheitan 



variety, or, as he is inclined to think, a distinct species, which he would call S. fastigiata, having 

 " the segments of its fertile fronds level-topped and exceedingly numerous, the appendages uniformly 

 four pair, as nearly as possible, in each spike, all of them erect and parallel, not divaricated 



the spikes recurved

We have received what we consider to be the same plant, from the E 



India Company, named by Dr. Wallich S. dichotoma : but here the appendages are not one-fourth 



the size of those we have figured
