Cibotium pruinatum Mett. in Kuhn. Linnaea, 36:150. 1869. 



Along streams in wet woods, near the Wahiawa, Kauai, and 

 on Kaholuamano (2818). The three forms referred to this 

 species differ materially from each other, and also from the 

 brief description which this plant has received. They are all 

 distinctly wooly-hairy beneath. No. 2600 is nearest to C. 

 glaucum, but differs in its hairy under surface. It is necessary 

 to study these forms in their native woods, before the species 

 can be well understood. 



August to October (2590, 2600, 2818). 



DAVALLIA Smith, Mem. Acad. Turin. 5:414, pi. 9. 1793. 



Davallia speluncae (L.) Baker, Syn. Fil. Ed. 2, 100. 1874. 



Common in upper Pauoa, Oahu, at 1500 feet elevation, and in 

 gulches on the ridge west of the Hanapepe river, Kauai, at 

 3000 feet. Also above Waimea, Kauai. Hillebrand seems to 

 have been rather unfamiliar with the vegetation of such an 

 easily accessible place as the heights of Pauoa, for he says: 

 "Rare, found by me on the Waianae mountains, Oahu, and 

 near Hilo, Hawaii, only." 



April to July (2072 Oahu, 2650 Kauai). 



Davallia strigosa Swartz, Syn. Fil. 98.. 1806. 



Said to be a very common fern on all of the islands of the 

 Hawaiian group. In Pauoa, Oahu, it was found in sheltered 

 places on grassy slopos, under bushes (2012), and on the out- 

 skirts of the woods at about 1500 feet elevation, in much damper 

 situations (2327). On Kauai, a less hairy form was found in the 

 valley of the main tributary of the Hanapepe river, growing in 

 shade under trees (2480). 



Davallia strigosa Swartz, var. 



In open places near the edge of the forest above Waimea, 

 Kauai, growing in great profusion, is a form which differs from 

 the above by having a narrower leaf, narrower and more veiny 

 pinnae, pinnules and segments. 



September 10 (2803). 



Davallia teniiifolia Swartz, Schrader's Journ. 2 : 88. 1800. 



This plant is very common in the lower woods where the 

 timber is thin, and seems to prefer drier situations than many 

 of the other ferns. Collected in Pauoa, Oahu, and on Kaholu- 

 amano, Kauai. 



April to October (2328).
