Acrostichum, belonging to the division of Linnzeus, with simple 
fronds, which differs entirely from the Calaguala, the Puntu- 
puntu, and all the other roots which are not species of the same 
_ genus. All others who have treated of the Calaguala have dif- 
fered in the description which they have given of it; a proof 
that they have spoken solely from information regarding the ge- 
nuine Calaguala, and this information is very doubtful, or appli- 
‘cable to various species of Polypodium. 
Although the Indian words Cchallahuala, or Calaguala, as it 
is now written, and Huacsaro, are familiar only to a few per- 
sons, and those Aimericans, I have thought proper to adopt the 
first as the trivial name of the Polypodium, and the second as 
that of the Acrostichum ; naming the former species Polypodium. 
Calaguala, and the latter, Acrostichum Huacsaro, it appearing 
that these Indian words originate from concurrent indications in 
the plants themselves, as I have before shown.
