DISTRIBUTION OF PLANTS. 



(No. 17). Epidendric " on the trunks of trees," but no rhizoma; frond delicate, 



four inches to a foot high, and simply pinnatifid. "Puna," Brackenridge. — Perhaps 

 the small pinnate species which grows on trunks on the mountains behind Honolulu. 



■ — ' nov. sp., (No. 18). Frond pinnate, devoid of black midrib; the segments puberu- 



lous, serrulate, and more horizontal. On trunks of trees, on the mountains behind 

 Honolulu. 



• ? (No. 19) ; paleje all over ; fr. as in small pinnate sp. ; but frond three feet high, 



tripinn., and the segments large, broad, and dentate. " On the mountains West of the 

 gap behind Honolulu," Brackenridge. 



? (No. 20) ; same habit as the last. Three to four feet high ; frond bipinn. ; fr. on 



the margin, so that visible on both sides of the frond; segments serrate, incurved. "On 

 the mountains West of the gap behind Honolulu," Brackenridge. 



? nov. sp., (No. 21). Delicate, tender, eight to ten inches high ; frond bipinn., 



the segments broad ; handsome fructification. Found by 3Ir. llich " on Hawaii," pro- 

 bably on the Western side of Mauna Hoa. 



? (No. 22). Frond large, three to four feet high, bipinn.; the segments broad, 



and dentate ; sori few. On the mountains behind Honolulu ; rare. 



? (No. 23); seeming distinct from Oahu sp., and more hairy stipe and upper side 



of the rachis. Habit of Thelypteris, but no indusium; frond pinn., the pinn. serrate. 

 Two and a half miles from the Great Crater, towards Mauna Roa. 



Doodia Kunthiana, Gaud. (No. 2; compare No. 1 Feejee Islands). On the mountains 

 behind Honolulu. 



Cyathea (No. 5). A tree-fern ; the trunk six feet or more high. On the mountains 

 behind Honolulu, at the elevation of fifteen hundred feet; by no means rare. 



Vittaria ; compare (No. 1) Taheiti (to the Feejee Islands). Puna, and elsewhere; fre- 

 quent. 



Pteris; compare (No. 1 Taheiti to the Feejee Islands, and) P. aquilina; under surface 

 tomentose. Tauai, Hawaii, and on the mountains behind Honolulu. 



; compare (No. 10) Feejee Islands. Frond pinnate, the lower segments ternate. 



Tauai. 



(No. 13). Three to five feet high; stipe white, and smooth; frond bipinn., the 



pinn. entire, somewhat incurved. Tauai; Puna; and apparently the same species, on 

 Mauna Kea. 



(No. 14); near P. alata, but not alate. On the Mauna Kaala ridge; and at the 



upper margin of the forest on Mauna Kea. 



(No. 15); segments wider than in the P. pedata of Puna. Oahu. 



Thelypteris (No. 8). Large ; frond pinnate, the pinn. dentate. Pahuhali, and elsewhere; 



frequent. 



? (No. 9) ; bipinn., and the pinn. deeply incised. Banks of stream, in the upper 



portion of the forest on Mauna Kea, at the elevation of about 4500 feet. 



— • (No. 10); frond pinnate, the pinn. dentate; sori near the margin. Frequent in 



wet ground ; in the valley behind Honolulu, and also around Hilo. 



(No. 11) ; fr. along the margin. On the mountains behind Honolulu. 



Nephrodium (compare No. 1 Metia to the Feejee Islands) ; near N. exaltatum ; three to 

 five feet high, and entirely smooth. Abounding in the lower portion of the forest on 

 Mauna Kea. — The same species apparently, having the stipe pubescent above. 



' ; perhaps distinct, the segments shorter. In the mountain-defile across West Maui.
