DISTRIBUTION OF PLANTS. 



nov. sp., (No. 8). Stems very short, hardly rising above the leaves; the leaves 



ciliate with long bristles. In a bog, on the tabular summit of Tauai. 



Nov. gen. Poac, (No. 1); calyx-glumes as long as the spikelet, which consists of about 

 eight florets; the florets scarious on the margin, and pointed. On Mauna Roa, from 

 the elevation of 3800 to 5000 feet. On Mauna Haleakala, from the elevation of 2.500 

 to 5500 feet. 



— (No. 2) ; perhaps not distinct, but apparently leafy at base, and tufts of hairs at 



the mouth of the sheaths; spikelets of three to four florets; habit of Agrostis. In the 

 environs of the Great Crater. 



Agrostis (No. 1); awned ; the panicle coarctate. On 3Iauna Roa, from the elevation of 

 9500 to 11,800 feet, " to within a mile of the 2d Station," Brackenridge. On Mauna 

 Kea, at the elevation of 13,000 feet. On Mauna Haleakala, at the elevation of 9500 

 feet, but the leaves seeming narrower. 



(No. 2); resembling the last, but no awns; leaves narrow, almost capillary; pani- 

 cle coarctate. Growing in tufts ; at the elevation of 5000 to GoOO feet on jMauna Roa. 

 In the pastoral district on Mauna Kea, to the elevation of 9000 feet. 



(No. 3) ; apparently a third species. Same habit, but taller, and the florets 



larger; awned; and the panicle coarctate. On iMauna Roa, from the elevation of 5000 

 to 6700 feet ; in a second specimen, the awns not made out. 



(dalamagrostis?. No. 1 ; recorded as) Arundoid?; the corolla awned, and hairs at the base. 

 Along the upper margin of the forest on the North flank of 31auna Haleakala, at the 

 elevation of 6700 feet. 



Aira (No. 1) ; compare A. flexuosa, but the awns very short or wanting ; leaves mostly I'adi- 

 cal, upright, and closely involute. On Mauna Roa, at the elevation of 6500 feet; rare. 



(No. 2) ; three feet high, growing in tufts. In the pastoral district on Mauna 



Kea, from the elevation of MlOO to 10,000 feet. On Mauna Haleakala, from the 

 elevation of 8000 to 9500 feet. — And apparently the same species, the leaves narrow, 

 at the base of Mauna Kea near Hilo. 



Trisetum (No. 1) ; like T. subspicatum, but much larger; growing in tufts. On Mauna 

 Roa, from the elevation of 5000 to at least 670U feet. On Mauna Kea, from the eleva- 

 tion of 8000 to 13,000 feet. On Mauna Haleakala, from the elevation of 5500 feet to 

 10,200, to within a few yards horizontally of the summit. 



Greenioid ? (No. 1). Multicaul ; panicle coarctate; corolla or seed, long-awned. Fre- 

 quent in the environs of the Great Crater. 



Lycopodium (No. 15); like L. clavatum. Creeping; spikes three together. In cracks 

 of the lava-surfiice, at the elevation of 0500 feet on Mauna Roa; rare. Apparently 

 the same species on Mauna Kea, at the elevation of 9500 feet ; on Mauna Haleakala, 

 to the elevation of 8000 feet; and specimens bearing four spikes, found by Rich and 

 Brackenridge on the "North flank of Mauna Kaala." 



nov. sp., (No. 16) ; habit of N. Amer. sp. ; fruit sessile. On the face of a rock 



on the North flank of Mauna Haleakala, at the elevation of about 7700 feet. 



nov. sp., (No. 17) ; habit of the last; smaller leaves. On the face of the same 



rock on the North flank of Mauna Haleakala, at the elevation of 7700 feet. Apparently 

 the same species, growing on the tabular summit of Tauai. 



Ophioglossum (compare No. 2 Samoa). Normal ; and like O. vulgatum of Europe. On 

 Mauna Haleakala; and on the tabular summit of Tauai. 



Acrostichum (No. 12) ; frond lanceolate, paleaceous. On Mauna Roa, growing in cracks
