 y. S. Am., especially on the Andes. I am a little doubtful about some of the S. Am. 

 specimens, which I refer here, and which are smaller and more robust, and rarely, if at 

 all, bipinnate ; especially a " W. crenata and W. canescens," of Mandon, from Bolivia, 

 alt. 2,700-3,800 metres, "Cistopteris vestita, Pr.,"from Brazil, and an unnamed plant from 

 Venezuela, Funck & Schlim, n. 981 : the peculiarities may, however, arise from great 

 elevation or other circumstances.
