So sportive are the forms of the pinnse in many of the species of this genus, that it is difficult to 

 characterize them in words. We have given the present plant under the name by which we received 

 it from the Honourable the East India Company : at the same time we must observe that it comes 

 very near to the Lhidsaa flabellata of Dryander, in the third volume of the Transactions of the 

 Linnean Society, p. 41. t. 8. f. 2. That species, however, difFers from ours, in being more decidedly 

 bipinnate, in having most of the pinnse larger, regularly flabelliform, and in the apices of the fronds 

 and compound pinnae being obtuse.
