DISTRIBUTION OF PLANTS. 



(No. 23); like A. serra. Two feet high; pinn. lobed, the lobes serrate; sori 



heading towards the apex of the nearest lobe. At the commencement of the forest on 



Mauna Ivea, at the saw-mill near Ililo. 

 nov. sp., (No. 24) ; habit of A. serra. Three feet high, strict ; segments longer 



than in the other species. Tauai. 

 (No. 25); like A. lucidum. Three to four feet high; frond pinnate, the pinn. 



minutely serrate, long-caudate. " Woods in the District of Puna," Brackenridge. 

 ? (No. 26) ; habit of Aspid. asplenioides. Tender and delicate ; frond tripinn. and 



incised ; indusium not made out. " Puna," Brackenridge. 

 (No. 27) ; a second species having the habit of Aspid. asplenioides. Large, four 



to five feet high ; frond bipinn., the pinn. pinnatifid ; indusium not made out. Upper 



portion of the forest on Mauna Kea, where the summits of the fronds were found 



blighted by frost ; growing also at Hilo, and in the District of Puna. 

 (No. 28; a congener? of No. 17 Feejee Islands). Habit of Adenophorus ; 



frond bipinn. ; the segments with rounded obtuse lobes, those next the rachis divided. 



" Puna, growing in tufts on the trunks of trees," Brackenridge. 

 (No. 29) ; a second species with recurved segments ; larger and longer ; frond 



long-caudate. " A graceful plant, frequent in certain situations in the Puna District," 



Brackenridge. 



; compare parsley-leaved sp. ; the stipe seeming more paleaceous ; rusty. Between 



the Great Crater and Mauna Roa. 



(No. 30) ; larger than parsley-leaved sp. ; sometimes viviparous; frond bipinn.; 



the segments broader, cuneate, lobulated. " Puna," rather rare, Brackenridge. 



(No. 31); habit of parsley-leaved sp., but multifid, and the lobes linear. On 



trunks of trees in the forest on Mauna Kea, at the elevation of 4000 feet; and appa- 

 rently the same species, larger, with broader segments and several sori, at the saw-mill 

 near Hilo. 



(No. 32); near parsley-leaved sp. ; pendent segments. In the mountain-defile 



across West Maui. 



? (No. 33) ; smooth ; sori extending close to the midrib. Hilo. 



? (No. 34) ; parallel sori ; stipe more woolly than in Hawaiian sp. (No. 33). 



" Mountains on the West side of the gap behind Honolulu," Brackenridge. 



Pinonia (No. 1). Ten to twenty feet high, and readily mistaken for a tree-fern; but the 

 real stem is very slender, edible, and does not become woody, the main portion of the 

 seeming trunk consisting of impacted fibrils that secure support by enveloping the up- 

 right stem of some neighboring woody plant; stipes smooth, but with quantities of 

 long soft gold-colored wool at base; sori marginal. Abounding in the Lower portion of 

 the forest on Mauna Kea; also on the mountains behind Honolulu. The downy wool 

 is collected in quantities, for stuffing pillows and similar economical purposes. 



? (No. 2) ; basal portion of the stipes rough, and bristly with long blackish hairs ; 



sori larger. In the forest on Mauna Kea. 



? (No. 3) ; perhaps a third species ?. The seeming trunk six feet high by two 



inches in diameter; under surface of the fronds green; no fructification. In the forest 

 on Mauna Kea, at the elevation of 3500 feet; growing also along the new lava-stream. 



Jungermania (No. 5). Between the Great Crater and Mauna Roa. 



(No. 6); a second species; larger leaves. "Environs of the Great Crater," 



Brackenridge.
