Phymatodes -percussum Cav., — Bom. et. Ch., Fil., p. 232. 



Common on trunks of trees in partial clearings near Castillo. 

 Specimens were also collected on a tile roof in the village of 

 Castillo. In tine fruit. The fronds vary from 3 to 10 inches 

 in length, and from 3§ to 1 inch in width. The smaller forms 

 are almost sessile, or with very short stipes, and the fruit is 

 restricted in most of them to the terminal half of the frond. 

 The larger specimens have stipes quite 2 inches long, and the 

 sori in some of them extend nearly to the base. 



The sterile fronds are shorter and broader. Free veinlets 

 occur in some of the areola?. 



Reported from Chontales by Fournier (as PIcopcItis), and 

 by Hemslev.
