Hab. Island of Madeira, near St. Anna: in woods. Sandwich 

 Islands, on East Maui : on the margin of a crater. 



In many of our specimens, from both localities, a small scaly bulb 

 is present on the stipe, a short distance below the inferior pair of 

 pinnae, from which spring one or two fronds : by a declination of the 

 stipe, these bulbs throw out roots into the ground, and a new plant 

 is thus formed. The plants from the two countries are in all respects 

 similar : that figured is from the Sandwich Islands.
