DISTRIBUTION OP PLANTS. 



? (No. 4) ; or compare Cyperus. A foot high ; striate swelling glumes. Frequent 



in the sands of the low Lsthnius on Maui. 

 Digitaria (No. 4 J compare Taheiti and the Feejee Islands). Decumbent, and entirely 



smooth ; growing on the new lava-stream. — And apparently the same species around 



Honolulu, like D. sanguinale, but very small and smooth. 

 Panicum (No. 4); normal. Environs of the Great Crater, from the elevation of 3000 



feet to 5000 on Mauna lloa. 

 nov. sp., (No. 5); near P. capillare. Growing in tufts; the sheaths somewhat 



hairy. Frequent in the environs of the Great Crater, as far as the elevation of 5000 



feet on Mauna Roa. — Apparently the same species, tall with pointed glumes, in the 



sands of the low isthmus on Maui. 



• (No. 6) ; perhaps not distinct from the Mauna Roa sp. ; but smooth-leaved. Tauai. 



(No. 7) ; compare P. capillare. Softly pubescent, and only four to eight inches 



high. Frequent in the sands of the low isthmus on Maui. 

 (Gen. near Panicum, No. 1) ; like a normal Panicum, but the third calyx-glume not 



found. Leaves short and rigid, with a white cartilaginous margin. Frequent on 



approaching the Great Crater. 

 ( ?, No. 2); the third calyx-glume not seen. Florets softly pubescent, together 



with the whole plant; which is niulticaul and dichotomously branching, forming sin- 

 gular matted bunches. Maritime ; growing on the Southeast coast of Hawaii; and 



apparently the same species, in the sands of the low isthmus on Maui. 

 Gen. Panicoid, (No. 1). Habit of Agrostis, niulticaul; long hairs on florets. On the flanks 



of Mauna Roa, at the elevation of 5000 feet ; rare. 

 (No. 2) ; a congener of Mauna Roa sp. ; hairy florets. Abounding in the sands 



of the low isthmus on Maui 

 ; the florets hairy, and seeming larger than in the last. Lahaina, on the Leeward 



side of West Maui. — Perhaps the same species in the mountain-defile across West Maui, 



the leaves sijiooth. 



Orthopogon ; compare (No. 1 Taheiti to the Feejee Islands). Frequent in woods; on 

 the mountains behind Honolulu, in the Puna District on Hawaii, and elsewhere. 



Cynodon dactylon, (bis Brazil, Peru, and No. 1 Taheiti to Tongatabu). On the sea-shore 

 of Oahu, and of the other islands. According to colonial Whites, this grass " forms 

 fine lawns." 



Eragrostis (No. 1). Three feet or more high; growing in tufts. Occupying tracts. 



Rhapis aeicularis, (No. 1, bis Taheiti to the Feejee Islands). Naturalized on Oahu, in the 

 District of Puna, and throughout the Group; in many places abundant, so as to be 

 annoying to the traveller; introduced, unintentionally, by aboriginal settlers. 



Bambos (bis Taheiti and No. 1 Samoa to the Feejee Islands) ; the leaves seeming less 

 rough than in Feejeean. " A brake near Pahuhali, and slender naked stems inter- 

 mingled, eight or ten feet high and full of fascicles of bulbs ?," Brackenridge. 



Saccharum oiEcinale, (No. 1, bis Metia to the Feejee Islands). Abundantly cultivated ; 

 having been introduced by aboriginal settlers. Other varieties, including some stocks 

 " from Taheiti," afterwards brought here by colonial Whites. 



Marsilea (No. 2; compare No. 1 Taheiti to the Feejee Islands). Growing in wet ground, 

 on Oahu and elsewhere; (perhaps indigenous).
