Typical specimens of this species were found rather spar- 

 ingly in the deep woods near Castillo. Hemsley and Four- 

 nier {ibid.} both report it from Chontales, the latter under the 

 name A. striatum.

One specimen only was found in the deep woods near Cas- 

 tillo. It is almost typical, but the pinnules are rather large, 

 and scarcely hairy on the lower surface. The rachises, and 

 to some extent the stipe, are covered with closely appressed 

 brown hairs.
