inches in diameter, and were more or less spiny. The fronds 

 were from 4 to 5 feet long, with blackish-brown, scaly stipes. 

 Reported from Chontales by Fournier (doubtfully), and by 

 Hemsley. 



Genus ALSOPHILA Brown. 



1. A. PHEGOPTEROIDES Hook. PL XVII, FigS. 4, 5. 

 Hook, and Bak., Syn. Fil., p. 32. 



Rather common in the deep woods near Camp Menocal. 



The fronds are tufted, and 2 to 4 feet long. 



Hooker and Baker {ibidS) describe the Nicaraguan speci- 

 mens exactly. The species is well-defined and is not easily 

 confounded with any other. 



The species is new to Nicaragua and to the entire Central 

 American region. It is not reported in the Biologia Cent. Am. 



2. A. infesta Kze. PL xvii, Fig. 6.

Only sterile specimens were found growing in tufts in the 

 higher deep woods near Castillo. Some were somewhat 

 arborescent. The upper surface of the frond is very dark- 

 green. The stipes are short-hairy, and when fresh were 

 dark-brown. 



Hemsley lists it from Guatemala, the only other locality in 

 Central America from which it has been reported.
