 Aspidium truncatum Gaud. Bot. Voy. Uranie 333, pi. 10. 1830.

Collected at elevations of from 3000 to 4000 feet, on Kauai. 

 On the ridge west of the Hanapepe river it was found growing

 Waimea it was more plentiful in deep woods along streams, 

 and was also of a much more luxuriant growth.

 lateral margins slightly recurved; veins free, producing a 

 branch on either side near the base of the pinnule, each of 

 which bears a short linear sorus which stands on the pinnule 

 half way from the main vein to the margin; sporangia short 

 stalked, 12 to 15 in a sorus.
