Between Yilla Kica and Escoba (418). January. 



The only tree fern that I met with in Paraguay, though there 

 must be other species. The stem is l-lj m. high, and 1-12 cm.

This was first determined as A. armata, Presl., and so distri- 

 buted. We are indebted to Mr. J. G. Baker for the correction.
