NATURAL HISTORY BULLETIN. 



Fine typical specimens of this variety were secured. The 

 pinnee vary from three to five in number, in well-developed 

 specimens, but young sterile fronds are simple, and vary 

 from ovate-cordate to hastately three-lobed. The bases of 

 the pinnas vary from somewhat acute through truncate to 

 cordate. Found rather sparingly in the rich soil of higher 

 deep woods near Castillo. 



Fournier (/did.) reports A. dolosum from Chontales. 



Whether he includes var. wilsotii or not has not been deter- 

 mined. Hemsley (ibid.) likewise reports A. dolosum (of which 

 ivihoni is given as a synonym) from Chontales.

A fine series of typical specimens was collected near Castillo. 

 The sterile fronds are mostly shorter, and much broader than 

 the fertile fronds, and are more or less glaucous on the lower 

 surface, especially when young. Linear -lanceolate dark- 

 brown scales (see figure) are scattered on the short stipe and on 

 both sides of the mid-rib near the base, being much denser on 

 the stipe and gradually diminishing in size and number upward.
