In what has been considered the normal state of this 
plant, the sterile fronds alone exhibit, and very indistinctly, 
serratures; the fertile fronds none. But beautiful specimens 
before us of this species (some of them 18 inches long), 
in full fructification, have the segments so strongly serrated 
that I at first looked upon this as a new species, and it 
certainly is that state of Cheilanthes intramarginalis^ which 
Martens and Galeotti published as distinct from that species 
under the name of Pteris fallax. It is a satisfaction to us to 
find that Mettenius in his recent work on the Genus Cheilan- 
thesy agrees with us in referring the plant to Cheilanthes^ rather 
than to Pteris, or Allosorus, or Pellcea, or Casseheera, or 
Platyloma, in which several genera it has been placed according 
to the respective views of authors who have written upon it.
