AFRO-INDIAN REGIONS.

The Hawaiian Islands are the most distant point on the Globe to 

 which Australian analogies extend ; and some of these are very 

 decided; as, the presence of Exocarjyus, of a lieteropliyUous Acacia, a 

 Doodia, and Epacridece. — New Zealand analogies are yet more inti- 

 mate and obvious ; in the presence of Edwardsia ?, Metrosideros, More- 

 Jotias, Myoporiim, and of an indigenous Draccena. Besides other forms 

 that occur throughout the Southern Hemisphere generally, or are 

 almost Antarctic ; as Nerfera, TJncinla, and Accena. 



Contrary to the state of things in Southern Polynesia, there are 

 American analogies upon the Hawaiian Islands ; one even within the 

 Lower or warm District ; the presence of Nama. On the mountains, 

 American analogies are more numerous: as, the presence of Gannera ; 

 of a Pteris resembling P. verticillata of the Peruvian Andes ; of Sisi/- 

 rincMum ; a Stema-lil-e Compos.; gen. Poa-IUce having the common 

 calyx enlarged, a red-tlowered Ruhus, and a yellow-flowered SanicvJa, 

 all three resembling Oregon species; besides Pliijllodegias, provided 

 that the Californian species prove congeneric. There are also on the 

 mountains, various general Northern and sub-Arctic forms. 



The following plants were found growing in the Inferior or warm 

 Region of the Hawaiian Islands; between the sea and the elevation 

 of 6700 feet on the mountains : 



(Nephroica) Ferrandiana, (No. 1); Cocculus of Gaudichaud. Seeds resembling those of 

 Menisp. Canadense; leaves ovate, acute. Tauai ; and at the elevation of four thousand 

 feet, in grassy places along the upper base of Mauna Roa.* 



Lepidium Owaihense, (compare No. 1 Paumotuan to Bellinghausen and Wake's coral- 

 islands). The leaves somewhat succulent. Tauai, Oahu, and elsewhere ; submaritime. 



Capparis nov. sp., (No. 2). Sometimes becoming a small tree, ten to iifteen feet high. 

 Oahu, Southeast coast of Hawaii, and elsewhere; keeping within a mile of the sea. 



Viola (No. 1). Normal, though becoming a shrub, upright, and one to two feet high ; 

 leaves ovate, cordate at base, long-pointed. On " Mauna Kaala," within the Leeward 

 portion of Oahu, Brackenridge. 



* The number of American and Mexican weeds is very striking ; some of them appa- 

 rently of Aboriginal introduction ; brought from the coast in ancient times by the 

 natives themselves, by Polynesian and Hawaiian navigators. 



Argemone (Mexicana ; compare United States and No. 1 Brazil); white-flowered. A 

 weed abundantly naturalized around Honolulu, and elsewhere; said to have been intro- 

 duced within the memory of resident Whites. 



Brassica oleracea, (bis Taheiti to Tongatabu, and No. 1 Europe) ; the cabbage. Abun- 

 dantly naturalized, especially in elevated situations ; having been introduced by trading 

 and colonial Whites. •
