Salpiclihrna volubile Smith, Ferns, Brit, and For., p. 209. 



The vine-like fronds of this splendid fern often climb in 

 clusters to a height much exceeding 25 feet. As only the 

 uppermost pinnae were fruiting it was exceedingly difficult to 

 secure fertile specimens, only two of which are in the collec- 

 tion. The specimens which were observed were typical, but 

 alternate pinna? were not rare. 



Common in deep woods near Castillo and Camp Menocal. 



Not heretofore reported from Nicaragua.

A. crenulatum Presl, Tent. Pter., p. 106. 



Common on trees in deep woods near Castillo and near 

 Camp Seven. The fronds were tufted, from short scaly 

 clustered rootstocks. The specimens are typical, but some 

 of them form obtuse lobes toward the apex of the frond. 



Hemsley and Fournier both report it from Chontales.
