Pteris decipiens Hook. Sp. Fil. 2:209. 1858. 



The first specimens of this fern were found at 1200 feet, 

 growing in crevices of moist rocks, at the Pali, Oahu, which is 

 probably the original station, as the type came from Oahu. 

 Later it was noticed at the foot of Hanapepe falls, Kauai, and 

 very handsome specimens were obtained in a ravine above 

 Waimea, where it grew on a rock shaded by Kukui trees. It 

 is an endemic species. 



March to October (1990). 



Pteris decora (Brack) Hook. Sp. Fil. 2:210. 1858. 



Dryopteris decora Brack. Bot. U. S. Expl. Expert. 16: 103, pi. 13, 

 f. 1. 1854. 



On exposed rocks below the forests, on the ridge west of the 

 Hanapepe river, and above Waimea, Kauai, both stations at ele- 

 vations of about 2000 feet. Professor Underwood says, " It is 

 doubtful if this species can be maintained as a Pteris." 1 I cer- 

 tainly had no idea that it was such when the specimens were 

 collected. It has been found only on the Hawaiian group. 



Pteris exeelsa Gaud. Bot. Voy. Uranie, 388. 1830. 



A line large fern, which grows in company with Davallia spe- 

 luncae and Asplenhim aspidioides, in damp gulches at eleva- 

 tions of about 3000 feet, on the island of Kauai. 



July 31 (2649). 



Pteris irregularis Kaulf. Enum. Fil. 189. 1824. 



Collected in dry open places on the margin of the woods 

 above Waimea, Kauai, at elevations of 3000 to 4000 feet. A 

 handsome species growing in clumps. 



August 31 (2782). 



Pteris regularis E. Bailey, Hawaiian Ferns, 26. 1883. 



A species of apparently local distribution, found in wet 

 gulches along streams. It was collected in Kalihi valley, Oahu, 

 at about 1200 feet elevation, and was also seen in Pauoa and from 

 the island of Kauai. Professor Underwood says: " A species 

 well characterized in Mr. Bailey's too modest pamphlet."
