Asplenium sphenotomiim Hillebr. Fl. Haw. Is. 599. 1888. 



In the woods of Kaholuamano, above Waimea, Kauai, at 4000 

 feet elevation, growing on the ground and on trees. A hand- 

 some fern, more plentiful in deep wet woods, than in the dry- 

 outer forest. 



September (2765). 



Asplenium vexans Underw. n. sp. 



Rootstock stout, ascending or erect, covered with the thickly- 

 placed bases of the fallen petioles; petioles about 25 cm. long, 

 with a dense tuft of dark brown scales at the base, smooth and 

 pale brown above; leaves membranous, triangnlar-ovate, about 

 30 cm. long, 20 cm. wide at the base, triquadripinnatifid; pin- 

 nae about 14 pairs, the lower widest in the middle, the upper 

 wider at base, all provided with a winged rachis; pinnules 2 to 

 3 cm. long, oblong- lanceolate, cut almost to the base into decur- 

 rent segments which in the larger pinnules are cut into 3 or 4 

 acute divisions, or in the smaller are entire or 2 to 3 toothed at 

 the apex; veins forked, single in each tooth; sori 4 to 6 to each 

 pinnule mostly confined to its upper half. 



On the ground, on Tantalus, and above Pauoa and Manoa, 

 Oahu, in damp woods under larger ferns. 



Allied to A. cicutarium in texture and habit. It bears a close 

 resemblance to A. scandicinum, and was probably confounded 

 with that plant by Hillebrand.

CIB0T1UM Kaulf. Berl. Jahrb. der Ph. 1820. 



Cibotium Chamissoi Kaulf. Enum. Fil. 230, pi 1, f. H. 1824.

 Manoa, Oahu, at 2000 feet elevation.

Cibotium menziesii Hook. Sp. Fil. 1 : 84. PI. 29 c. 1846. 



Common in damp woods along the Wahiawa, Kauai, at 2000 

 to 2500 feet elevation, and on Kahaluamano above Waimea. 

 This species is easily distinguished from the others by the long 

 brown hair on the stipes, and to an observant person the whole 

 plant presents a different appearance from any of the other 

 species.
