The greater part of the specimens enumerated belong to the form called flexuosa, 
which Fournier retains as a distinct species; and Eaton (Proc. Am. Acad. xviii. p. 187) 
says that in well-developed fronds the zigzag habit is very conspicuous, and it is, 
perhaps, as well to keep the two (7. e. P. cordata and P. flexuosa) apart.
